Atoms and Matter

a subatomic particle with a positive charge found in the atom's nucleus. The number of protons tells what element an atom is.

• electron

• orbital

• proton

• neutron

a measurement of the amount of matter in something. We use kilograms to measure it in science, and it's measured like weight, but not the same thing.

NGSS.MS-PS1-5

a subatomic particle found in the atom's nucleus with no charge. It has the same mass as a proton.

• neutron

• electron

• proton

• nucleus

a subatomic particle with a negative charge found in the orbitals of an atom.

• neutron

• nucleus

• electron

• proton

the spaces around an atom's nucleus where electrons are found. There are different levels of orbitals in an atom.
