Three different atomic cations that have 22 protons-
Atomic cations are atoms that have a positive electric charge.
(Chromium) Cr has 24 protons therefore, Cr2+ has = 24 - 2 ⇒ 22 protons.
(Manganese) Mn has 25 protons therefore, Mn3+ has= 25-3 ⇒ 22 protons.
(Iron) Fe has 26 protons therefore, Fe4+ has= 26-4 ⇒ 22 protons.

Cr²⁺, Mn³⁺ and Fe ⁴⁺ are the chemical symbols for three atomic cations with 22 electrons.
The number of protons inside the nucleus always remains constant.
∴Chemical symbol of three different atomic cation that have 22 electrons-
1. Cr²⁺
2.Mn³⁺
3. Fe⁴⁺
Atomic cation is the ion with positive electric charge on it, it means it should have more protons than electrons.
•Chromium (Cr) has 24 electrons therefore, Cr²⁺ will have = 24- 2 ⇒22 electrons (+2 charge means it will lose 1 electron from its outer shell)
•Manganese (Mn) has 25 electrons therefore, Mn³⁺ will have = 25-3⇒ 22 electrons. (+3 charge means it will lose 3 electrons from its outer shell)
•Iron (Fe) has 26 electrons therefore, Fe⁴⁺ will have = 26-4 ⇒ 22 electrons. (+4 charge means it will lose 3 electrons from its outer shell)
