lithium has a 1+ charge, and oxygen has a 2− charge. a lewis dot diagram should contain one lithium atom and two oxygen atoms to show how these atoms form an ionic bond.
true
false

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 :

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

The electronic configuration of oxygen is:

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

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.

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

Explanation: Oxygen plays a very vital role in the life of aquatic animals. The dissolved oxygen in the water helps them to breathe under water.

Optimum level of oxygen for deep living animals like oysters, bottom feeders, crabs is around (1-6 mg/L), while the animals living on the upper side like fishes require a higher amount of around (4-6 mg/L).

If the oxygen concentration in the pond is not optimum, there will no aquatic life and hence, the ecosystem will be affected.

Hence, oxygen concentration affects the fishes that live in the pond to a higher extent.
