Question

You are given an element 16X8. Find out
a. Number of protons, electrons and neutrons in X.
b. Valency of X.
c. Write the name of element X.

Answer 1

a. Number of protons= 8

   Number of electrons= 8

   Number of neutrons= 8

b. Valency of X= 6

c. Element X is Oxygen.

Answer 2

You are given an element $^{16}X_{8}$. Find out

a. Number of protons are 8, electrons are 8 and neutrons are also 8 in X.

b. Valency of X is 2.

c. The name of element X is oxygen.

Explanation:

• When an element is represented in the form of $^{a}X_{b}$. Then "a" represents the atomic mass of the element, that is, sum of total number of protons and neutrons present in it.

• Whereas "b" represents the atomic number of the atom, that is, total number of protons present in it. For example, the element $^{16}X_{8}$ has atomic mass 16 and atomic number 8.

• This means that this element contains 8 protons, 8 electrons and 8 neutrons. Valency is the tendency of an atom to gain or lose electrons in order to complete its octet.

Hence, the valency of $^{16}X_{8}$ is 2. Name of this element is oxygen.
