pretty sure it's [H] 2s(little2) 2p(little1)
Boron has the electronic configuration:- 1s2, 2s2, 2p1
[He] 2s2 2p1
The electron dot formula for a monoatomic hydrogen is (H.). However, elemental hydrogen is diatomic, so most hydrogen atoms would be found as (H:H). Please note the parentheses above are for clarification and are not part of the electron dot diagram.
The electron-dot structure of sodium atom is 'Na-dot' or 'Na.' One dot is one valence electron.

It is K with one dot so: K . The reasoning behind this is that you put the highest energy level on the dot notation. Electron Configuration notation for Potassium is: 1s2; 2s2, 2p6; 3s2, 3p6, 4s1. It is also in the third row, so that is why it moves up to the fourth energy level.
Elctrons give off forms of light, which appear as dots. Using these dots use 4.7x10^5.
