Question

write the electronic configuration of 12 Mg​

Answer 1

Explanation:

the Magnesium electron configuration will be 1s² 2s² 2p6 3s².

or

ANSWER

Magnesium has atomic number 12. It will be distributed in K, L, M shell in the following way:

K shell can accommodate a maximum of 2 electrons.

L shell can accommodate a maximum of 8 electrons and

M shell will accommodate 2 electrons

So the configuration becomes 2,8,2.

hope it's helpful

Answer 2

Electronic configuration of Magnesium is 1s² 2s² 2p⁶ 3s².

1. Magnesium is a metallic element found in periodic table. It belongs to s block elements with specific presence in alkaline earth metals.
2. They form basic oxides.
3. It belongs to period 3 and thus have three shells of electron.
4. Loss of two electrons results in formation of ionic form of magnesium.
5. Nearest noble gas to magnesium is Neon.
