Question

BRAINLIESTTT ASAP!! PLEASE HELP ME :)

Answer 1

Answer : False, there will be two lithium and one oxygen atoms in a unit molecular structure of lithium oxide.

Explanation:

Electronic configuration of lithium is :

$Li=1s^2s^1$

In order to attain stable electronic configuration it will loose an electron and form positively charge cation.

$Li^+=1s^22s^0$

The electronic configuration of oxygen is:

$O=1s^22s^22p^4$

Oxygen being second most electronegative atom requires two electrons to attain noble gas configuration stability and form negatively charge ion with 2- charge.:

$O^{2-}=1s^22s^22p^6$

When two atom of lithium and oxygen comes together , one electron from each lithium atom get transferred to an oxygen atom which results in formation of lithium oxide.

$2Li^++O^{2-}\rightarrow Li_2O$

Answer 2

HELLO :)

The answer would be false because the Lewis plot should contain 2 lithium atoms & 1 oxygen atom.

Since the lithium atom only contains 1 valence electron, then it wouldn't be enough to fill the valence shell of the oxygen atom because the oxygen only has 6 valence electrons in its valence shell. So it needs one more, that why it would need 2 lithium atoms.

hope this helps :P
