How many protons and valence electrons does oxygen have?

Answer 1

Oxygen has 8 protons- the atomic number is the number of protons an atom has. A single oxygen atom contains 8 electrons to balance this charge, but oxygen is diatomic- meaning it will be O2 instead of just one Oxygen molecule.

Answer 2

If you refer to the Periodic Table, go to symbol "O" which represents Oxygen. The number on the top represents how many protons it has in its stable state. In the case of Oxygen it will be eight. Now when an atom is in stable state, number of protons will equal number of electrons. So Oxygen atom has eight electrons.

Answer 3

Oxygen has atomic number 8 meaning a single oxygen atom has 8 protons and 8 electrons BUT

the question is about O2. The O2 molecule of 2 oxygen atoms will have 16 protons and 16 electrons.

Answer 4

All oxygen atoms contain 8 protons in their nuclei. All neutral oxygen atoms have 8 electrons. There are three isotopes of oxygen, containing 8,9, or 10 neutrons in their nuclei.

Answer 5

Number of Protons = Atomic number = 8 for oxygen Uncharged, an atom of oxygen will also have 8 electrons

Answer 6

Oxygen's atomic number is 8. That means it must have 8 protons and 8 neutrons to be electrically neutral. Out of those 8 electrons, 6 of them are valence electrons.

Answer 7

Oxygen has 8 protons and 8 electrons.

Answer 8

8 protons, 10 electrons, valence 2

Answer 9

8 of each
