Answer:

Both are made of two or more atoms.

Explanation:

A compound is two elements that are mixed together, no matter the amount element that it´s in the compound, it can be from 2 atoms to thousands of tons, those are still compounds, and molecules are 2 atoms of the same element that are together, so both are made 2 or more atoms, in the case of the molecule its two atoms of the same element, and in the case of the compound is two atoms of different elements.

Alexus [3.1K]

Answer: Option (b) is the correct answer.

Explanation:

A covalent bond is defined as the bond which occurs due to sharing of electrons between the combining atoms.

Generally, a covalent bond is formed between non-metals.

For example, both nitrogen and oxygen atoms are non-metals and they combine covalently to form NO_{2} compound.

As nitrogen has 5 valence electrons and an oxygen atom has 6 valence electrons. So, there occurs unequal sharing of electrons between the two.

Thus, we can conclude that when a covalent bond forms then electrons in valence shells are shared between atoms.

Matter is anything that has mass and occupies space, It can exist in 3 states, or phases: solid, liquid, and gas.

Solid molecules are closely packed together and retain a fixed shape.

Liquid molecules aren't packed very closely, and take the shape of the bottom of the container.

Gas molecules are far apart and fill the container

completely.
