Question

Write the electronic configuration of the atom.If the number of electrons in an atom is 12 and the number of the proton is also 12.

Answer 1

Answer:

2 8 2 and it is magnesium mark me brainliest

Answer 2

Answer:

2, 8, 2 K, L, M shell

or

1s2 2s2 2p6 3s2

Explanation:

no. of electrons = atomic no. of  that element

that is a magnesium atom, which has atomic no. 12

no of protons = no. of electrons  means that the atom in neutral

so the electronic configuration is

2,8,2 in K, L, M shells

or

1s2 2s2 2p6 3s2
