Study the diagram and answer these questions: there are electrons in the n = 1 orbit of each atom. each atom has electrons in its n = 2 orbit. each atom has protons in its nucleus. each atom has electrons. there electrons in oxygen's outer shell before sharing electrons. there electrons being shared between the two atoms. bonds exist between the two oxygen atoms.

2 electrons in the n=1 orbit
6 electrons in its n=2 orbit
8 protons in nucleus
8 electrons
6 electrons
4 electrons shared
Covalent bond exist between the two oxygen atoms

Explanation:

The n = 1 means the first shell of an atom whereas n = 2 means the second shell of an atom and so on.

As every atom consists of three sub-atomic particles which are protons, neutrons and electrons.

Protons and neutrons reside inside the nucleus of an atom and electrons revolve outside the nucleus of the atom.

A covalent bond is defined as the bond formed by sharing of electrons between the two combining atoms.

Therefore, the given questions are answered as follows.

There are 2 electrons in the n = 1 orbit of each atom.Each atom has 8 electrons in its n = 2 orbit, after the sharing of electrons take place between both the oxygen atoms.Each atom has 8 protons in its nucleus.Each atom has 8 total electrons.There are 6 electrons in oxygen's outer shell before sharing electrons.There are 4 electrons being shared between the two atoms.Double bonds exist between the two oxygen atoms. This is because sharing of two electrons is taking place. Hence, a double covalent bond exists when two oxygen atoms when they chemically combine together.

Ithink 2 is the correct
