Question

what is the electronic configuration of scandium​

Answer 1

Explanation:

Ar 3d¹ 4s²

Atomic number: 21

Symbol: Sc

Atomic mass: 44.955912 u

Answer 2

Ar 3d¹ 4s²

Atomic number: 21

Symbol: Sc

Atomic mass: 44.955912 u

Atomic number of Scandium -21

Configuration:: 1s² 2s² 2p6 3s² 3p6 4s² 3d¹

In shell 1=1s²=2

In shell 2=2s²+2p6=2+6=8

In shell 3=3s²+3p6+3d¹=2+6+1=9

In shell 4=4s²=2

Therefore,. 2, 8, 9, 1
