Title: Isotopes of Atoms


1
Isotopes of Atoms
Kristin Dykstra and Bill Howard Hopkinton Middle
School
2
Isotope
  • Atoms of the same element that have different
    masses

Due to varying number of neutrons
Iso same
3
Hydrogen
4
Hydrogen - 1
1 is the mass number!
1 (mass ) -1 (atomic )
No neutrons!
Also called Protium
5
Hydrogen - 2
2 is the mass number!
2 (mass ) -1 (atomic )
one neutron
Also called Deuterium
6
Hydrogen - 3
3 is the mass number!
3 (mass ) -1 (atomic )
two neutrons
Also called Tritium
7
Lithium - 6
6 is the mass number!
6 (mass ) -3 (atomic )
3 neutrons
8
Lithium 7
7 is the mass number!
7 (mass ) -3 (atomic )
4 neutrons

Frequency of Isotopes
1.0079 H 1
Atomic mass close to 1
H-1 (Protium) is the most common isotope of
hydrogen.
Protium- 99.985
Deuterium- .015
Tritium- 0 Not naturally occurring
10
6.941 Li 3
Atomic mass close to 7
Lithium-7 is the most common isotope
Lithium 7- 92.58
Lithium 6- 7.42

  • food sterilization
  • airport security
  • measurement gauges
  • luminous paints
  • smoke detectors
