Question

$(\sqrt{3 \div 2} )2$
​

Answer 1

The atomic number and mass number of sodium are 11 and 23 respectively.

This suggests that number of proton in sodium =11 and number of nucleons i.e. proton and neutrons in sodium =23. Thus, number of neutrons =12 and also Since no. of protons = no. of electrons =11

So, they are similar.
