4. Choose any 10 elements with atomic # less than or equal to 92 (Uranium) and make page about each element describing a few of their chemical characteristics (atomic
number, metal/nonmetal, # of valence electrons, etc.) AND a fun fact. Be sure to inclu-
the elements name, symbol, atomic mass and number. Remember on the first page
starting this section to describe what atomic # and mass #is! Total: 10 pages

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
