Electronic Configuration of First 30 Elements with Atomic Numbers.

Atomic Number Name of the Element Electronic Configuration

4 Beryllium (Be) [He] 2s2

5 Boron (B) [He] 2s2 2p1

6 Carbon (C) [He] 2s2 2p2

7 Nitrogen (N) [He] 2s2 2p3

(3) Explanation: There are two properties that can be used to identify an element: the atomic number or the number of protons in an atom. The number of neutrons and number of electrons are frequently equal to the number of protons, but can vary depending on the atom in question.
