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

An atom of sodium-23 (atomic number = 11) has a positive charge of +1. give this information, how many electrons does it have? how many proteins and neutrons does this atom have

In a water molecule, hydrogen and oxygen are held together by a(an) bond. a) double covalent b) ionic c) nonpolar covalent d) hydrogen e) polar covalent

Which statements are true concerning mineral formation? check all that apply. the slower the cooling, the larger the crystals. the faster the cooling, the smaller the crystals. crystals formed from magma are smaller than crystals formed from lava. minerals can only form in solutions when the solution is heated deep underground. when a solution cools, elements and compounds leave the solution and crystallize as minerals. minerals formed from hot water solutions can form narrow channels in the surrounding rock.
