Question

The table lists the number of protons, electrons, and neutrons in a certain radioactive nuclide. Electrons Protons Neutrons 11 11 13 Which is the symbol of this radioactive nuclide?

Answer 1

A is the answer, which is 24/ 11 Na

Answer 2

Explanation:

It is given that number of electrons is 11.

Number of protons is 11.

Number of neutrons is 11.

It is known that when an atom is neutral then the number of protons equals number of electrons. Also, atomic number means number of protons an atom holds.

Whereas mass number equals number of protons + number of neutrons. Thus, mass number of given atom is 11 + 13 = 24.

The symbol for this element will be as follows $^{24}_{11}X$. This atom sodium has atomic number 11 and mass number 24.

Therefore, symbol of this radioactive nuclide is as follows $^{24}_{11}Na$.
