1. properties of matter that can be changed without
changing the material
2. rows on the periodic table
4. determines the number of protons in an element
6. the center of the atom
9. the abbreviation of the name of an element
10. columns on the periodic table
12. a bond that is caused by the strong attraction of two oppositely
charged ions
13. atoms that have gained or lost electrons
14. a covalent bond in
which one element gets
to spend more time with
the electrons than the
other
16. phase of matter in which
molecules are not connected
17. atoms of one elements that
have different numbers of
neutrons
