Making Models of Isotopes

Opening Assignment Pre –Lab activity Read page 108 in your textbook. 1. Add the definition of the following science terms to your notebook Isotope Mass number 2. How many protons and neutrons does Carbon-13 have?

What is an isotope? Ions --- has extra electron(s) or missing electron(s) An isotope is an atom that is missing neutron(s) or has extra neutron(s). Isotopes -- similar to ions except instead of electrons isotopes have a different number of neutrons.

Draw the Bohr’s model of Lithium

Or another way indicate it is an isotope is…… Lithium - 7
