1 H Hydrogen Element: The simplest form of matter Atom : the smallest piece of matter that can be identified as an element.

1 H Hydrogen Atomic Name : Hydrogen

1 H Hydrogen Atomic Number: Indicates the number of: protons electrons in a neutral atom.

1 H Hydrogen Atomic Mass: Measured in Atomic Mass Units or (AMU). 1 AMU is equal to the mass of a proton. DO NOT round the mass to the nearest whole number

1 H Hydrogen Atomic Symbol 1 or 2 letters. The symbol comes from its English or Latin name.

Calculating the number of Protons Atomic # = # of Protons Ex: Hydrogen Atomic # = 1 # of Protons = 1

Calculating the number of Electrons # of Protons = # of Electrons Ex: Hydrogen # of Protons = 1 # of Electrons = 1

Calculating the number of Neutrons Atomic Mass ( rounded to the nearest whole # ) - Atomic # = # of Neutrons Ex: Hydrogen Atomic Mass = 1 Atomic # = = 0 Hydrogen has no neutrons.
