Isotopes Standard C-2: The student will demonstrate an understanding of atomic structure and nuclear processes.

ISOTOPES Isotopes: An atom that has the same number of protons as other atoms of the same element do but that has a different number of neutrons.

ISOTOPES There are about 2000 different isotopes that are known. Of this number, only 279 are stable-they do not change over time.

RADIOISOTOPES Radioisotopes - the nucleus will decay (change) over time and release radiation-energy or particles. This change is spontaneous-occurs without action/intervention.

ISOTOPES Uranium-238 OR 238 U 92

U U Nuclear Symbol Format 238 235 92 92 This uranium atom has 92 protons and 146 neutrons This uranium atom has 92 protons and 143 neutrons
