What best explains how two oxygen atoms, each with six valence electrons, can bond with each other?

one atom can lose two electrons so that the other atom can gain them and have eight valence electrons.

one atom can lose four electrons to the environment so that a total of eight valence electrons remains.

each atom can share two electrons with the other so that each atom has eight valence electrons.

each atom can lose two electrons so that there is a total of eight valence electrons between the atoms.

Explanation: Oxygen atom has atomic number = 8

One oxygen atom has 6 valence electrons.

Electronic configuration of Oxygen =

Oxygen atom forms a covalent bond with another oxygen atom. Covalent Bonding is the bonding in which sharing of electrons between two atoms takes place so that both the atoms complete its octet.

If two oxygen atoms bond together, they both share two electrons to complete their octet resulting in the formation of double bond between them which makes it a stable molecule.

Lewis dot structure of molecule is given in the image attached.

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.
