Answer: Group 6
Step-by-step 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-
