Question

What is electron protron neutron in Na?

Answer 1

`11` protons, `11` electrons, and `12` neutrons.

Explanation:

On the periodic table, `Na` is sodium, and is element number `11`. Therefore, it has `11` protons. Since it is a neutral element, it will also have `11` electrons.

Also, sodium has an atomic mass of `23` amu, and so it means that it has a total of `23` neutrons and protons.

There are `11` protons, and so there'll be `23-11=12` neutrons.
