Question

Element a has 3 electrons in the outermost orbit and element b has 6 electrons

Answer 1

Answer:

Explanation:

Element A has 3 electrons in the outermost orbit an element B has 6 electrons in the outermost orbit .the formula of the compound formed by A and B would be.

Answer 2

Answer:

  B has 6 electrons in its outermost shell, so it will tend to gain 2 electrons. So the respective charges of both the elements will be A=+3 and B=-2. So by crossing the charges, we get A2B3. A has 3 electrons in its outermost shell, so it will tend to lose 3 electrons.
