6. Elements A and B have 3 and 6 electrons in their outermost shells, respectively. (a) Which element will gain electrons and how many, while forming a chemical compound? What will be the electrical charge on the ion of that element? (b) Which element will lose electrons and how many, while forming a chemical compound? What will be the electrical charge on the ion of that element?

Answer:
u can choose nceart for solving
Explanation:
In a neutral molecule, the sum of the bonding valance electrons must be equal. So the products of the negative element and its charges and the positive element and its charge must be equal.

If we have a 3 valance electrons , the 'A' charge will be either +3 or -5 for a full octet and valance electron in 'B' atoms will mostly result in acquisition of additional electrons (2) for an octet and relative charge of -2.
Balancing the two,
3 × A = -2 × B
To be equal, A = 2 and B = 3
