Answer:
The electron configuration of a Ca2+ ion is 1s22s22p63s23p6
Explanation:
Answer:
1s², 2s², 2p⁶, 3s², 3p⁶
Explanation:
The general configuration for a regular Calcium atom is :
1s², 2s², 2p⁶, 3s², 3p⁶, 4s²
But it mentions it is a Ca²⁺ ion.
This means it has lost 2 electrons.
Therefore, the configuration is :
1s², 2s², 2p⁶, 3s², 3p⁶
