Answer 1

Answer:

Explanation:

Proton is the positively charged particle present in atoms of all the elements.

Hydrogen only has one electron and therefore has a configuration of 1s1. In order to fill it's energy level it only needs one more electron obtain a full outershell (1s2). This is why we only put two electrons on Hydrogen atoms when drawing Lewis structures.

A proton is about 1835 times more massive than an electron. If you are asking about their physical dimensions - no one knows. Scientists currently do not know how small electrons are.
