An atom wants to have a full octet and thus the number of valence electrons is the key to finding how many bonds should be formed to complete this octet.
For example: H2O
Oxygen has 6 valence electrons. To achieve a full octet (i.e. eight valence electrons on the outermost shell), it needs two more electrons. Hydrogen has 1 electron available for bonding, thus two hydrogen atoms would provide oxygen with the two electrons it needs. Thus the compound, H2O is formed.
Another example is CO2
Carbon has 4 valence electrons. Oxygen has 6. Each wants a full octet. Thus, carbon shares two of its valence electrons with each oxygen. In the end, Carbon has its original 4, plus two from each oxygen atom, which totals to eight. Oxygen has 6 originally plus 2 shared electrons from carbon thus a full octet is achieved.
If its' valence shell is full. If it isn't then it will bond with other atoms until it has a full valence shell.
it needs altogether 13 electrons more
Valence electrons-electrons that are farthest from an atoms nucleus- are the electrons that form bonds with other atoms.
Helium is a noble gas and it is chemically stable.It does not have valence electrons to form bonds.
Valence electrons are the electrons in the outermost shell. They are the electrons available for bonding and generally determine the number of bonds an atom can make
Chemical bonds are formed by the sharing or donating of electrons. The electrons that atoms use to make chemical bonds are the outermost electrons, also known as valence electrons.
No, they arent. Valence electrons are the amount of electrons the element has in its outermost shell. Electrons dont bond, they can either be shared or transferred. An ionic bond transfers electrons and a covalent bond shares electrons.
Valence electrons are used to form bonds. These are present in outermost shell.

Covalent bonds are formed by sharing electrons of the valence shell.
Look at double bonds and dotted valence. Double or more bonds equals a linear shape. Also... 2 bonds = linear 3 bonds = linear if dbl or trpl bonded, otherwise bent 4 bonds = triginal poly Etc.

by the transfer of the valence electrons

Valence electrons occur in the outermost shells of an atom. Valence electrons can be shared in covalent bonds. Covalent bonds occur between non-metals, like Carbon and Nitrogen.
their valence electrons are free-roaming they allow for the conductivity of electricity APEX :) <3 JAmie
Fluorine has seven electrons. Fluorine will form covalent and ionic bonds. Ionic- If it combines with any metal Covalent- If it bonds with a non-metal
