they need to either gain or lose electrons to create an octet. It depends on the atom.
an octet is when an atom has a full outermost energy level
Atoms can fill their outermost energy level by either gaining electrons from other atoms or by sharing the outermost electrons with another atom.
They would have to connect with other atoms to create a new atom
The outermost energy level of an atom typically has between 1 and 8 electrons.
An atom of magnesium has two valence electron. It can have a full outer level by losing two electron. The second energy level becomes the outermost energy level with eight electrons.
Covalent Bonds. :)
8
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
It is the most stable element in the universe and does not need anymore electrons. Its outermost energy level is full.
Yes, the outermost energy level of the atoms of the noble gases are filled, meaning that they have the maximum number of electrons. This is why noble gases are stable and unreactive. The atoms of reactive elements share or transfer electrons in order to fill their outermost energy levels, making them stable like the noble gases.
Nonmetals, they fill out their outermost energy level by gaining electrons.
It would gain 2 electrons.
They may either form covalent or ionic bonds with more atoms.
