Question

what are the electron configuration for the following elements: sodium, boron, carbon, and oxygen.

Answer 1

Answer:

sodium 2,8,1

boron 2,3

carbon 2,4

oxygen 2,6

Answer 2

Answer:

The electronic configuration of given elements are -

Sodium : 1s2 2s2 2p6 3s1

Boron : 1s2 2s2 2p1

Carbon : 1s2 2s2 2p2

Oxygen : 1s2 2s2 2p4

Explanation:

The electronic configuration is the distribution or arrangement of electrons of an element or its ionic or molecular form in its atomic or molecular orbital. The electrons get filled up in orbitals according to their energy levels.

• Sodium (Na) is made up of 11 electrons , hence the electronic configuration is 1s2 2s2 2p6 3s1.

• Boron (B) - is made up of 5 electrons, hence the electronic configuration is 1s2 2s2 2p1
• Carbon (C) - is made up of 6 electrons, hence the electronic configuration is 1s2 2s2 2p2
• Oxygen (O) - is made up of 8 electrons, hence the electronic configuration is 1s2 2s2 2p4
