Periodic Table

period

• Elements that occur in vertical columns on the periodic table.

• A horizontal row of elements in the periodic table

• Found in group two of the periodic table; highly reactive

• A subatomic particle that has a negative charge

neutron

• A subatomic particle that has a positive charge and that is found in the nucleus of an atom

• not able to conduct heat or electricity, little to no metallic luster

• A subatomic particle that has a negative charge

• A small particle in the nucleus of the atom, with no electrical charge
