Which of the following is true of ionic bonds (choose all answers you think are correct) A. Transferring of valence electrons creates the bond

B. The bond is created by oppositely charged metal and nonmetal atoms.

C. Electrostatic attraction results in the arrangement of charged atoms in a regular, geometric structure called a crystal lattice.

D. Moving electrons become de localized between the atoms creating the ionic bond.

E. Sharing Valence electrons between nonmetal atoms creates the bond

  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-

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.
