How many electrons does oxygen have in its outer most shell?

Answer 1

Oxygen has 8 electrons. If using the basic shell electron arrangement in has 2 in the inner shell and 6 in the outer most shell. If you use the advanced system 1s2, 2s2, 2p4. This means 2 in inner shell, 2 in next shell and 4 in its outer shell. The simple method is what they teach at gcse not at a level.

Answer 2

The atomic number is the same as the amount of electrons an atom has. Since the first shell can only hold 2 electrons and the second shell can hold up to 8 electrons, and Oxygen has 8 electrons, then it must have two shells with 2 electrons on the first and 6 on the next.

If you want to skip all the gab:

2 shells

8 electrons

2 on the first shell

6 on the next shell

Answer 3

Oxygen has an atomic number of 8.

The first energy shell holds 2 electrons.

The second energy shell holds up to 8 electrons.

For oxygen there are 2 electrons in the first shell and 6 in the second (outermost) shell

Answer 4

Because "orbital shell" is a confusing term to me (several orbitals, also called sub-shells, exist within each energy level), I will cover several aspects of oxygen's electrons in fear of not answering your question.

In its neutral state, oxygen has a total of 8 electrons. Its electron configuration is 1s2 2s2 2p4. This means that the s orbital is filled in both the first and second energy level, and the p orbital has 4 of the 6 electrons it is capable of holding. Px, py, and pz all have one electron, and the fourth electron could be in any of the three.

Oxygen, of course, has a tendency to share electrons with other atoms because of its high electronegativity. That having been said, the other forms of oxygen (that are not neutral) will not be covered in this totally awesome answer. :)

Answer 5

6.

Answer 6

O is atomic number 8, so it has 8 protons and 8 electrons. The electron configuration would be
1s2 2s2 2p4. So, it has 2 electrons in the first shell (1s2).

Answer 7

Oxygen has 6 outer shell electrons.

Answer 8

Oxygen has 6 electrons in its outermost shell.

Answer 9

6 electrons
