Which group in the periodic table would have an an ion of a -2 charge?

Group 6

Explanation:

There are eight (8) groups in the periodic table. Elements in Group 6 include OXYGEN, SULPHUR etc.

These elements have an outermost shell with 6 electrons; thus, they are always ready to RECEIVE two electrons from possible donors to form a completely filled outermost shell.

For example

Oxygen has atomic number of 8, its configuration is 2, 6

Sulphur, has atomic number of 16, its configuration is 2, 8, 6

Each require TWO electrons to attain stable octet structure, so, will accept two electrons and become an ANION with -2 charge

O2 + 2e- ---> 2O-

S2 + 2e- ---> 2S-

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."

each  column  of the  table  is called a group. elements in a group share similar properties. groups are  read  from  top  to  bottom. metal. metalloid. nonmetal. solid. liquid. gas. fe. hg. o.  2. 3. 4. 5. 6. 7. 8. 9.  2. beryllium. 9.012. 4.  sodium. 22.990.  11. 3.  magnesium. 24.305.  12.  potassium. 39.098.  19. 4.  calcium. 40.078.  20. i guess  i
