You're talking about calcium right?

Ca = 1s2, 2s2, 2p6, 3s2, 3p6, 4s2

Ca+2 = 1s2, 2s2, 2p6, 3s2, 3p6

(18 ions)

Answer: The ion formed is
Z^(2+)

Step-by-step explanation:

An ion is formed when an atom looses or gains electron.

  • When an atom looses electrons, it will form a positive ion known as cation.
  • When an atom gains electrons, it will form a negative ion known as anion.

We are given:

Atomic number of element Z = 20

The electronic configuration of neutral atom =
1s^22s^22p^63s^23p^64s^2

The electronic configuration of the ion =
1s^22s^22p^63s^23p^6

As, the given element is loosing 2 electrons. So, it will form a positive ion having charge of +2.

Hence, the ion formed is
Z^(2+)
