Question

write the chemical symbols for three different atomic anions that all have 6 protons.

Explanation:

Step1: Identify the element

The number of protons determines the element. With 6 protons, the element is carbon (C).

Step2: Form anions

Anions are negatively - charged ions. We can form anions by adding electrons to carbon.

• $C^{2 - }$: Carbon gains 2 electrons.
• $C^{3 - }$: Carbon gains 3 electrons.
• $C^{4 - }$: Carbon gains 4 electrons.

Answer:

$C^{2 - }$, $C^{3 - }$, $C^{4 - }$
