Question

1. how many electrons will the following atom have: Na*

2.when you change the number of protons in an atom it becomes an?

Answer 1

Na is in group 1, when it becomes ionized is assumes the electron configuration of a noble gas (as this makes it stable), the closest noble gas is Ne. Na it loses 1 electron to achieve Ne's electron config and becomes the cation \(Na^+\).

Answer 2

when you change the number of protons in an atom you change the identity of said atom
