- Q1
Atoms are created from elements, all of which are located on the Periodic Table. Atoms, which are the smallest particles on Earth, are made up of several different parts. The part of the atom that is located in the outer layers is the-
part of the atom with a mass and no charge.
part of the atom with no charge and no mass.
part of the atom with no charge and a small mass.
part of the atom with a negative charge and no mass.
