1s2 2s2p4
In other words, it has 3 shells, the 1s shell, the 2s shell and the 2p shell.
Wiki User

How many electrons does oxygen need to fill its outer shell?
10 electrons
How many electrons does nitrogen require to fill its outer shell?
Its atomic number is 7, and so it needs a further 3 electrons to fill its outer shell.
An oxygen atom has 6 electrons in its outer shell how many electrons does it need to fill that shell?
They all have 6 in its outer shell because they are all in the same group in the periodic table. Your VERY VERY welcome (:
How many electrons does Magnesium have in its outer most shell?
Magnesium has a total of 12 electrons. The electron configuration would be 1s2 2s2 2p6 3s2. Therefore, 2 electrons in it's outer shell.
Why is oxygen O2 not O?
Oxygen usually exists in the form of diatomic molecules, meaning each molecule contains two oxygen atoms. These molecules form because a lone oxygen atom is two electrons short of a full outer shell of 8. In order to fill its outer shell one oxygen electron will share electrons with another. Each oxygen atoms "gains" two electrons from the other. A total of 4 electrons are shared between them, 2 from each atom, creating a double covalent bond..
How many electrons does oxygen need to fill its outer shell?
10 electrons
How many electrons are needed to fill carbon outer shell?
Carbon has four valence electrons, so it will need four more electrons to fill its outer shell.
How many electrons does nitrogen require to fill its outer shell?
Its atomic number is 7, and so it needs a further 3 electrons to fill its outer shell.
How many valence electrons will beryllium gain or lose to fill its outer shell?
Beryllium will lose 2 electrons to satisfy the octet rule (to fill its outer shell).
If carbon has four electrons in its outer shell does it completely fill its outer selectron shell?
Yes. Two of the electrons will go into the carbon's outer s shell (2s) to completely fill it (s orbitals can contain up to two electrons) and the remaining two will go into its outer p shell (2p).
How many number of electrons to fill the outer shell of carbon?
Carbon has four valence electrons, so it will need four more electrons to fill its outer shell.
How many electrons would be needed to fill its outer shell for carbon?
4 to fill the 2p shell
How many electrons are needed to fill up carbons outer shell?
4 to fill the 2p shell
An oxygen atom has 6 electrons in its outer shell how many electrons does it need to fill that shell?
They all have 6 in its outer shell because they are all in the same group in the periodic table. Your VERY VERY welcome (:
A total of how many electrons are needed to fill the outer shell of most atoms?
There is a total of 8 electrons that are needed to fill outer shell of most atoms. An atom is the smallest unit of matter.
What is the number of electrons to fill outer shell of sulfur?
6
