Explanation:
1) region outside the nucleus divided into energy levels : electron cloud
Energy levels are specific spherical orbitals around the nucleus. The region of maximum probability of where an electron is located is called an electron cloud or orbital.
2) located in the outermost energy level, determines how element will react chemically with other elements: valence electrons
Valence electrons are electrons in the outermost energy shell of an atom. They determine whether an atom will react chemically with other elements of not.
3) outermost energy level
: valence shell
The valence shell where the outermost electrons are located is the outermost energy level.
4) atoms that have the same number of protons but different numbers of neutrons
: isotopes
Isotopes are atoms having the same number of protons but different number of neutrons. They generally have the same chemical properties. They have the same atomic number but different mass number.
5) located in the nucleus, neutral or no charge
: neutrons
Neutrons are subatomic particles in the nucleus with no charges on them.
6) located outside the nucleus, negative(-) charge
: electrons
Electrons are subatomic particles that carries negative charges
7) located in the nucleus, positive(+) charger: protons
Protons are positive charges in the nucleus of an atom.
