Neutrons add MASS to an atom.
you cant add proton to an atom...u can only add electron....
The atom becomes a negative ion.

it becomes a molecule. when you add molecules and atoms, they form matter.
Neutrons are neutral particles, so they donâ??t change the charge of an atom. They do however, change the atomic mass.
The electron.

When you view the screen you will see three atoms which are two light pink and one light purple atoms. You will begin by adding atoms that are in the lower part of the screen. First, add one green atom above the light pink atom and one green atom below the light purple atom. Next, add one green atom below the light pink atom, one green atom to the left of the light pink atom and then another green atom below the green atom you just added. Add three green atoms directly above the light purple atom. On the same three atom chain at the top, add a blue atom to the left of the green top atom. The light pink atom that is alone on the grid is next. You will add four blue atoms. They will be placed in the following order. One blue atom above the light pink atom, one blue atom below the light pink atom, one blue atom to the left of the blue atom and one blue atom to the right. This will complete your analyzation of the hammer.
