Energy level/ energy shell

• the area surrounding the nucleus of an atom

• where the electrons move around the nucleus

Valence electrons

• the electrons in the outermost/last energy shell

• electrons with the most energy

• electrons used in bonding atoms together

Isotope

• atoms with the same number of protons and electrons, but a different number of neutrons

• atoms of the same element but with a different atomic mass

•

Niels Bohr

• created a model of the atom that show electrons on specific energy levels, but can jump from one energy level to another.

• (think- the atom picture from the Big Bang Theory show or Jimmy Neutron)

Lewis Electron Dot Diagram

• is a representation of the valence electrons of an atom that uses dots around the chemical symbol of the element
