Binding Energy Carbon

Introduction to binding energy of carbon:

To begin with a discussion on binding energy of carbon, let us begin with the atom of carbon. Carbon atom has six electrons, six neutrons and six protons. A carbon atom combines with another carbon atom by forming a bond between them. These bonds are necessary for the existence of carbon molecule and for different chemical reactions. It is one of the elements, which is fond the most naturally. The quantity of energy that is required to haul the proton and neutron apart considerably is known as binding energy. Let us study carbon’s binding energy in detail. Having problem with Atomic Mass Carbon keep reading my upcoming posts, i will try to help you.

Description of Binding Energy of Carbon

The distance between the centers of the atoms bonded together is called as the bond length. Bond order is the electron pair number. These electron pairs are shared between the atoms for forming bonds. In case of carbon-carbon bond, the bond order is 2. In order to break the bond between the carbon-carbon bonds, the binding energy between the two atoms needs to be countered. The energy required to break the bond is called bond dissociation energy or bond energy. Generally the bond lengths between the atoms of a particular element remain the same. As the lengths are the same, the bond energy also remains the same.

Studies shows that the shorter the bond length, the higher the binding energy.  The following is a table of different substances, including carbon. Please express your views of this topic Basic Physics Formulas by commenting on blog.

The table gives a comparison of the bond lengths and binding energies of the different elements and molecules of compounds.

Conclusion for Carbon’s Binding Energy

From the discussion made on binding energy of carbon, binding energy of carbon can also be defined as the enthalpy change on a reaction to break the bonds. The binding energy between the carbon atoms exists due to the C-C bond. These are covalent bonds which are formed by equal sharing of electrons.

Marie Curie Radioactivity

Introduction to Marie Curie radioactivity

The study of nuclear physics began when Becquerel discovered radioactivity in 1869, just one year after the discovery of X-rays. He found that accidentally, that an ore containing uranium emits an invisible radiation that can penetrate a black paper wrapper and expose a photographic plate. The rays are called as radioactive rays. Madam Marie Curie and her husband Pierre Curie conducted the most significant investigation in the field of radioactivity. After several years of careful and the laborious chemical separation process on tons of pitchblende, a radioactive ore, the Marie Curie reported the discovery of two previously unknown elements, both of them were radioactive. These were named polonium and radium. Madam Marie Curie was awarded Nobel Prize in 1903 for the discovery of radium. I like to share this Curie Law with you all through my article.

Marie Curie Radioactivity

Radioactivity is the spontaneous phenomenon exhibited by the heavy elements only. It is the property of the heavy elements, which disintegrates itself without being forces by any external agent. The total number of radioactive elements known at present is about 40. The natural elements with atomic number more than 82 are all radioactive, for example, Radium, Thorium, Actinium, Polonium etc. The phenomenon of radioactivity is not affected by pressure, temperature, chemical changes etc. The electrons orbiting around the nucleus are not responsible for the phenomenon of radioactivity.

Laws of Marie Curie Radioactivity

The laws of Marie Curie radioactivity are as follows:

(i) Radioactivity is a spontaneous process, which does not depend upon external factors like temperature, pressure etc.

(ii) During disintegration of an atom, either an alpha particle or a beta particle is emitted. Both of these particles are never emitted simultaneously. At a time, an atom will not emit more than one alpha particle or more than one beta particle.

(iii) The emission of alpha particle from an atom will change it into a new atom whose mass number is reduced by 4 and the atomic number be reduced by 2.

(iv) The emission of beta particle from an atom will change it into a new atom whose mass number remains same and the atomic number be increased by 1.

Drift velocity

The drift velocity that a particle such as an electron attains due to an electric field. Also see the velocity definition.Also see the given link to know about average velocity.

Since current is proportional to drift velocity, which is, in turn, proportional to the magnitude of an external electric field, Ohm's law can be explained in terms of drift velocity.
Drift velocity is expressed in the following equations: , where J_drift is the current density, σ is charge density in units c/m³, and v_avg is the average velocity of the carriers (drift velocity).

Example:Calculate the drift velocity of electrons in a metal conductor of area of cross-section lO^Wfor a current of 20A. Assume that there are 8-4 x 10²⁸ electrons per cubic metre; Charge on the electron = 1-6 x 10~¹⁹C.
Solution
We know that
I = n₀ev_dA; Drift Velocity v =——

U.S. navy veteran scam

The man who once rubbed shoulders with GOP political luminaries is  wanted by Ohio state authorities who say the $100 million he raised in the name of a charity for U.S. Navy veterans cannot be located.

He used the names Bobby Thompson and Ronnie Brittain, but authorities said that both were stolen identities. The U.S. Navy Veterans Association,his charity, ran its national headquarters in Washington, D.C., out of a post office box at a UPS store.
Ohio Attorney General Richard Cordray blamed that this alleged con artist had done "in the charitable sphere what Bernie Madoff did in the investment sphere. It's shocking and discouraging and to think so many people wanted to give to veterans and in fact they were giving to this man and his sham organization."

Thompson collected around $100 million over the past decade from donors who thought they were contributing to a legitimate veterans service organization, according to Cordray, and 99 percent of the funds are now unaccounted for. He donated to mostly Republican prominent politicians, more than $200,000 to.

To know about the meaning of scam, you can refer to tutorvista scam definition.Here, you will find information about what exactly is scam about.

Paid survey scam

Most of us get easily hooked on earning money using survey sites. Paid survey sites may pay you a pittance for completing surveys. Most sites look very organized and professional but these are most likely to be scams. Here is what you need to know about Paid Survey Scams

1)You should not have to pay a registration fee or membership fee to take a survey

2) Never give your credit card number when you make payments

3)Even though the site specifies that the payment is a one time fee, there is no guarantee that it is; victims warn that they were repeatedly charged membership fees. There are some scam sites though that offers a money back guarantee.

4)If you get a genuine paid survey site, then it a great work at home job.

5) Testimonies are not always true. They could be bogus stories that are used to lure victims.

6)Check out what the forums say about paid survey scams.

7) Even though the website looks genuine it could be a scam.

There is proof that some one really got paid. The cheque is featured with a very attractive amount. This alone does not prove that paid surveys are scam free.

The information you provide to paid survey scam sites are sold to other scammers.

- Check out the paid survey site and make sure that it's not a scam. Perform a 'whois' to check the credentials of the site

- Check the Better Businesses Bureau, if a complaint has been logged against the survey site.

- Never trust sites that are trying to prove that they are a genuine site and talk about scams. These paid survey sites generally turn out to be scams.

- The paid surveys which are scams say they pay between $ 50 - $ 60 per survey.

- A trick that paid survey scammers use is once you complete a couple of surveys they entice you to take on higher paying surveys. But in order to do this you need to provide personal information such as you likes and dislikes, your financial burdens, your personal assets and so on.

- Genuine Paid Surveys sites do not ask for registration and membership fees.

- Check the surveys out; some of them are not even realistic. These sites are scams

- Communicate with people who work from homes, especially those who work with surveys.

- If you find the right survey site stick to it. Those sites that promise huge fees maybe a scam.
