There are 5 electrons and it needs another 3 to be complete.
2 in the inner shell, 5 on the outer shell
Nitrogen has five electrons in its outer shell. It needs three more to achieve a noble gas configuration.
Its atomic number is 7, and so it needs a further 3 electrons to fill its outer shell.
Chlorine has 7 electrons in the outer shell. It requires one electron to fill the outer shell.
Nitrogen, atomic #7, has 5 valence electrons, since 2 are required to fill the first shell, leaving 5 in the outer (valence) shell.
Carbon needs 4 electrons to fill its outer shell. Two of the six electrons are in the inner "s" shell, and the remaining 4 stay in the outer "p" shell.
Carbon has four valence electrons, so it will need four more electrons to fill its outer shell.
Beryllium will lose 2 electrons to satisfy the octet rule (to fill its outer shell).
It has 6 electrons in the outer shell so it needs 2 more electrons for it to be completely full.
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).
4 electrons are required to fill the outer shell of a carbon atom. This, the second shell of carbon, can contain two 2s electrons and six 2p electrons, but in a neutral carbon atom it actually contains only two 2s electrons and two 2p electrons. Therefore, four more electrons are required to fill the outer shell.
When they attempt to stabilize themselves. For atoms to be stable they have to have a full outer shell of electrons and so they gain electrons to fill the current outer shell, or lose electrons in order for next shell in (which is full) to be the outer shell.
4 to fill the 2p shell
4 to fill the 2p shell
Two: The other two electrons in Be fill the inner shell.
As Nitrogen (N) have atomic number 7, and electronic configuration is 2,5. therefore N required 3 elecrons to complete their outermost shell or orbital.
Each noble gas has an 'octet' of electrons, meaning a full outer shell of 8 electrons, except for Helium which only needs 2 electrons to fill the outer shell.
Atoms are more stable when they are sharing or transferring electrons, and they either want to help another atom fill its outer shell with electrons or fill it own outer shell.
Oxygen needs 2 electrons to fill it's valence shell which is why it forms a 2- ion.
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.
