What type of particle results from the formation of a covalent bond? proton ion atom molecule

molecule

Explanation:

Covalent bond is the type of bond formed when there is sharing of electrons between two similar or different atoms.

1. Proton is the subatomic particle of an atom which is present in the nucleus of atom and bears positive charge.

2. Ions are formed when there is a loss or gain of electrons in an atom.

3. An atom is smallest unit of a matter or substance.It consist of three subatomic particles : electrons, protons, neutrons.

4. Molecules of element is a pure substance which is formed by bonding of atoms of similar elements. Example: .Molecule of compound is a pure substance which is formed by bonding of atoms of different elements combined together in a fixed ratio by mass.  Example:

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
