The electric charge of macroscopic bodies is actually a surplus or defieciency of electrons. Why not protons?

Text Solution

AI Generated Solution

To understand why the electric charge of macroscopic bodies is attributed to the surplus or deficiency of electrons rather than protons, we can break down the explanation into a series of logical steps. ### Step-by-Step Solution: 1. **Understanding Atomic Structure**: - An atom consists of a nucleus containing protons and neutrons, with electrons orbiting around the nucleus. Protons carry a positive charge, while electrons carry a negative charge. 2. **Charge Imbalance**: ...

(a) Explain the meaning of the statement ‘electric charge of a body is quantised’. (b) Why can one ignore quantisation of electric charge when dealing with macroscopic i.e., large scale charges?

Assertion : When bodies are charged through friction, there is a transfer of electric charge from one body to another, but no creation or destruction of charge. Reason : This follows from conservation of electric charges.

Which of the following is correct regarding electric charge ? (i) If a body is having positivr charge i.e. shortage of electrons (ii) If a body is having negative charge i.e. excess of electrons (iii) Minimum possible charge = +- 1.6 xx 10^(-19) C (iv) Charge is quantised i.e. Q = +- n e , where n = 1 , 2, 3, 4 ....

J.C. Slater proposed an empirical constant that represents the cumulative extent to which the other electrons of an atom shield (or screen) any particular electron from the nuclear charge. Thus, slater's screening contant sigma is as : Z^(**)=Z-sigma Here, Z is the atomic number of the atom, and hence is equal to the actual number of protons in the atom. the parameter Z^(**) is the effective nuclear charge, which according to is smaller than Z, since the electron in question is screened (shielded) from Z by an amount sigma . Conversely, an electron that is well shielded from the nuclear charge Z experiences a small effective nuclear charge Z^(**) . The value of sigma for any one electron in a given electron configuration (i.e., in the presence of the other electrons of the atom in question) is calculated using a set of empirical rules developed by slater. according to these rules, the value of sigma for the electron in question is the cumulative total provided by the various other electrons of the atom. Q. Which of the following statement is correct?

In Millikan's experiment, static electric charge on the medias has been obtained by shining X-rays. if the static electric charge on the oil drop is -1.282 xx 10^(-18)C . Calculate the number of electrons present in it.

Assertion : Millikan's experiment established that electric charge is quantised. Reason : From this experiment mass of the electron could not be determined.
