10 electrons
It needs 2 electrons

Its atomic number is 7, and so it needs a further 3 electrons to fill its outer shell.
Oxygen needs 2 electrons to fill it's valence shell which is why it forms a 2- ion.
They all have 6 in its outer shell because they are all in the same group in the periodic table. Your VERY VERY welcome (:
Magnesium has a total of 12 electrons. The electron configuration would be 1s2 2s2 2p6 3s2. Therefore, 2 electrons in it's outer shell.
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..
Carbon has four valence electrons, so it will need four more electrons to fill its outer shell.
Its atomic number is 7, and so it needs a further 3 electrons to fill its outer shell.
Oxygen needs 2 electrons to fill it's valence shell which is why it forms a 2- ion.
Beryllium will lose 2 electrons to satisfy the octet rule (to fill its outer 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).
Carbon has four valence electrons, so it will need four more electrons to fill its outer shell.
4 to fill the 2p shell
4 to fill the 2p shell

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.
