2. a row in the periodic table
4. the quality or condition of being reactive
6. a solid material which is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivity
10. A subatomic particle found in the nucleus of every atom with a positive charge
11. Relating to or denoting electrons involved in or available for chemical bond formation
12. A type of chemical bonding that arises from the electrostatic attractive force between conduction electrons and positively charged metal ions
14. The body of delocalized electrons that surrounds positive metal ions in metallic bonds.
15. a positively charged ion
16. a negatively charged ion

1. a table of the chemical elements arranged in order of atomic number, usually in rows, so that elements with similar atomic structure (and hence similar chemical properties) appear in vertical columns.
3. a column in the periodic table
5. any of the set of metallic elements occupying a central block (Groups IVB–VIII, IB, and IIB, or 4–12) in the periodic table
7. A chemical bond that involves the sharing of electron pairs between atoms
8. A type of chemical bonding that involves the electrostatic attraction between oppositely charged ions
9. an element or substance that is not a metal
13. A subatomic particle found in the nucleus of every atom with a neutral charge
14. a stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids.
