H → 1s¹
He → 1s²
Li → 1s² 2s¹
Be → 1s² 2s²
B → 1s² 2s² 2p¹
C → 1s² 2s² 2p²
N → 1s² 2s² 2p³
O → 1s² 2s² 2p⁴
F → 1s² 2s² 2p⁵
Ne → 1s² 2s² 2p⁶
Elements are named according to there atomic number in the periodic table.
The number of electron in an electronically neutral atom is equals to the number of protons.
The number of protons is also the atomic number of that element.
