I am struggling with understanding this review question, I have changed the numbers to practice the problem again later on. If I have a 2.5 gram copper penny and it has a charge of -2.0×10-9C (i) How many excess electrons are on the penny? (ii) By what percent do the excess electrons change the mass of the penny? If the penny's mass remains the same but the charge changes to 4.0×10-9C (iii) How many electrons have been removed from the penny? (iv) If only one electron is removed from the atom, what percent of the atoms are ionized by this charging process?
Atomic Structure
The basic structure of an atom is defined as the component-level of atomic structure of an atom. Precisely speaking an atom consists of three major subatomic particles which are protons, neutrons, and electrons. Many theories have been stated for explaining the structure of an atom.
Shape of the D Orbital
Shapes of orbitals are an approximate representation of boundaries in space for finding electrons occupied in that respective orbital. D orbitals are known to have a clover leaf shape or dumbbell inside where electrons can be found.

If the penny's mass remains the same but the charge changes to 4.0×10-9C
(iii) How many electrons have been removed from the penny?
(iv) If only one electron is removed from the atom, what percent of the atoms are ionized by this charging process?
Any help would be greatly appreciated :)
