Question

write the chemical symbols for three different atomic cations that all have 22 protons.

Explanation:

Step1: Identify the element with 22 protons

The number of protons is the atomic number. An element with 22 protons is titanium (Ti).

Step2: Determine possible cations of titanium

Titanium can form cations by losing electrons. Common oxidation states of titanium include +2, +3, and +4. So the cations are $\text{Ti}^{2+}$, $\text{Ti}^{3+}$, and $\text{Ti}^{4+}$.

Answer:

$\text{Ti}^{2+}$, $\text{Ti}^{3+}$, $\text{Ti}^{4+}$
