- 2. a law stating that the elements, when listed in order of their atomic numbers (originally, atomic weights), fall into recurring groups, so that elements with similar properties occur at regular intervals.
- 3. the horizontal rows on a periodic table
- 5. minimum energy required to remove the most loosely bound electron of an isolated gaseous atom, positive ion, or molecule.
- 7. Dull, poor conductors of heat and electricity, when solid they are brittle and unnmalleable.
- 8. is the tendency for an atom of a given chemical element to attract shared electrons when forming a chemical bond.
- 9. elements in the last group on the periodic table.
- 11. distance between the nucleus and valance electron of an element
