Corrected question- Write the chemical symbol for three different atomic cations that all have 12 electrons.
The number of protons inside the nucleus always remains constant.
∴Chemical symbol of three different atomic cation that have 12 electrons:
Atomic cation is the ion with positive electric charge on it, it means it should have more protons than electrons.

Al⁺, Si²⁺ ,P³⁺ are the atomic cations with 12 electrons.
∵The nucleus always contains the same number of protons.
∴Three distinct atomic cations with 12 electrons each have the following chemical symbol:
1. Al⁺
2. Si²⁺
3. P³⁺
An ion or atomic cation with a positive electric charge is thought to have more protons than electrons.
• Aluminum (Al) contains 13 electrons, hence Al+ will have = 13 - 1→ 12 electrons (1 electron will be lost for every additional charge).
• Si2+ will have = 14 - 2→ 12 electrons since silicon (Si) has 14 electrons. (+2 charge signifies electron loss of 2);
• Because phosphorus (P) has 15 electrons, P3+ will have 12 electrons because 15-3. (+3 charge indicates that 3 electrons will be lost.)
Hence, Aluminium, Silicon and phosphorus cations have 12 electrons.
