1. +4

2. 0/Neutral/No Charge

Explanation:

1. If the atom first loses an electron then it will have 22 protons and 18 electrons. Each electron's charge is -1 and each proton's charge is +1 so if there are 4 less electrons than protons, this means the number of positive charges outnumber the negative charges by 4 so the overall charge will be +4.

2. Similarly, if it gains 3 electrons, it would now have 22 protons and 22 electrons. Because there is an even number of protons and electrons, all the charges balance each other out because there is the same number of both charge so the overall is 0/neutral.

Hope this helped!
