Alithium atom has three protons, three neutrons, and three electrons. what is the overall charge on this atom? a–3 b 0 c 1 d 3

  Lithium atomic number = 3

  Li atom has 3 protons,3 electrons.Then it has no charge.

So the charge of Li atom here is zero.

Option b: 0 is the right answer.

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
