- 7. the property of metals that means they can easily be bent into shapes without breaking.
- 8. the vertical columns of the periodic table that are also known as families.

Down
- 1. this family is located in group 8 or 18 and does not want to bond with anyone.
- 3. this family has characteristics of both metals and nonmetals.
- 4. the scientist in the atomic theory that used his gold foil experiment to identify a positively charged center, or nucleus.
- 5. when the number of protons and electrons are equal in an atom.
- 9. this family of elements are brittle and break easily, they become anions because they gain electrons.
- 12. this family becomes a cation when it loses one electron, it is also located in the first group of the periodic table.
- 14. the ability to transfer heat and electricity, copper is a very ____.
- 15. a negatively charged particle that orbits around the nucleus and can be removed or added to make an ion.
- 16. when a gas atom gains electrons and becomes more negatively charged.
- 18. the rows of the periodic table that determine the number of rings and atomic radius of an atom.
- 20. the neutral particle in the nucleus of an atom that adds to the atomic mass but has no impact on ions.
