An atom has eight protons. what would need to happen for the atom to have an overall charge of 2

Explanation:

It is known that when an atom is neutral in nature then it holds same number of protons and electrons.

For example, an atom that has eight protons will be having eight electrons.

So, in order to complete its octet this atom needs two more electrons. Hence, it will readily accept two electrons from an electron rich atom.

Therefore, by gaining two electrons it will acquire a charge of -2.

Therefore, we can conclude that if an atom has eight protons. Then gain of two electrons would need to happen for the atom to have an overall charge of 2.

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
