Help! Help! 911! 1. What part of the atom is involved in ionic bonding?
2. Ionic compounds are made of one element that is a and one element that is a .
3. What is an ion?
4. Metals will electrons and become ions with a charge.
5. Non metals will electrons and become ions with a charge.
6. An ion with a +3 charge means the atom has electrons.
7. An ion with a -2 charge means that the atoms has electrons.
8. The formula for potassium chloride would be .

the only liquid elements at standard temperature and pressure are bromine (br) and mercury (hg). although, elements caesium (cs), rubidium (rb), francium (fr) and gallium (ga) become liquid at or just above room temperature.

explanation:

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-

i wish i could but this one is weird give me abc and i can solve it.
