What is the correct electron configuration for Ca?

Answer 1

Long-hand version: 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 Short-hand version: [Ar] 4s^2 Note: The "^" symbol means the the following number is in the form of a superscript.

Answer 2

20Ca2: 1s2 2s2 2p6 3s2 3p5 3d1

maybe 20Ca2: 1s2 2s2 2p6 3s2 3p5 3d1

Answer 3

Calcium has the atomic number 20 and is part of Group II. This means that the electron configuration is [Ar] 4s2.

Answer 4

The electron configuration of the cation Ca2+ is 1s22s22p63s23p6.

Answer 5

Any element has electrons equivalent to the atomic number of the element. So 20 electrons in 20Ca.

Answer 6

The electronic configuration of the element with atomic number 20 (calcium) is [Ar]4s2.

Answer 7

The electronic configuration of the element with atomic number 20 (calcium) is [Ar]4s2.

Answer 8

2 8 8

Answer 9

[Ar]
