Daniel Radcliffe Sings the Element Song

Another Version of the Element Song

Element a basic substance of matter; contains only one kind of atom

Atomic Number the number of protons in an atom of an element

Atomic Mass the average number of protons and neutrons in the nucleus of an atom

Mendeleev • the first person to arrange elements in order of atomic mass (almost 150 yrs. ago) • * the elements are now arranged by atomic number*****

Symbol • H = hydrogen • Ag = silver

Protons particle in the nucleus (positive)

Electrons particle outside the nucleus of an atom (negative)

Neutrons uncharged particle in the nucleus of an atom (neutral)

Phases of Matter Solid, liquid, gas, artificial

Stair Step Line separates the metals from the nonmetals: mercury is the only liquid metal, bromine is the only liquid nonmetal

Groups 1 -18 elements that react in similar ways to other substances (group # 1 has the strongest reactions)

Atomic Number 47 Ag Atomic Mass Silver 107. 9 Symbol Element’s Name

Elemental Funkiness
