Consider an imaginary ion ${}_{22}^{48}X^{3 -}$ . The nucleus contains ' $a$ ' $%$ more neutrons than the number of electrons in the ion. The value of ' $a$ ' is

Answer:

Solution:

${{}_{22}^{48}X}^{3 -}$
In an atomic representation ${}_{Z}^{A}X$
Z is atomic number = 22
A is atomic mass number = 48.
No. of protons $= Z = 22$
No. of neutrons $= A - Z = 48 - 22 = 26$
No. of electrons $= P - charge = 22 + 3 = 25$
$%$ of extra neutrons than electrons $= \frac{26 - 25}{25} \times 100 = 4 % = a %$
So, the value of a=4.
