Question

If element X has 99 protons, how many elctrons does it have?

Answer 1

the same amount. the number of protons is always equal to the number of electrons in a normal state without electric flow. they balance each other out. protons are positive, electrons are negative.

so the number of electrons in this case is 99

Answer 2

It has 99 electrons because an element has the same number of protons and electrons
