Question

Is that right the mass number of zinc is 98 and the atomic number is 30

Answer 1

Given, the number of the protons in zinc, Z=30

The atomic mass number, A=68

The atomic mass number is given by the sum of the number of protons and neutrons.

The symbol of an element is written as,

`^{mass\text{ number}}_{atomic\text{ number}}El`

Thu the symbol of zinc is,

`^(68)_(30)Zn`
