What role do valence electrons play in the formation of compound from elements?

Valence electrons are the electrons on the outer most shell of a neutral atom; they are used when forming chemical bonds with other atoms. Because of the octet rule - which is a chemical bonding theory based on the assumption that in the formation of compounds, atoms exhibit a tendency for their valence shells to either be empty or a full 8 electrons (octet) - atoms that do not have an octet need to either get rid of their electrons or gain more electrons. Atoms combine with other atoms in order to stabilize themselves.
For example if sodium and chlorine were to combine sodium would need to lose 1 valence electron while chlorine would need to gain 1 valence electron.
Na + Cl ------> NaCl
FYI NaCl, sodium chloride, is table salt.
*NB* All elements react in order to become stable and either get an octet or empty their shell. They are all attempting to be like the noble gases, which are hellium, neon, argon, krypton..etc. FYI noble gases are all stable and have 8 valence electrons.

The electrons in the valence shell form chemical bonds with other atoms in order to form compounds.

A compound composed of two elements that share valence electrons?
binary covalent bond
The elements within a group have a similar number of?
Elements in the same group have the same number of valence electrons. These are the outer-shell electrons that react with other elements.
Valence electrons are involved in what?
Valence electrons are involved in bonding to other atoms.
Where do elements have the same number in valence electrons?
Elements in the same group have the same number of valence electrons.
Where are elements with the same number of valence electrons?
All elements in the same group have the same number of valence electrons.
A compound composed of two elements that share valence electrons?

How many valence electrons are transferred from the nitrogen atom to potassium in the formation of the compound?
Potassium loses one valence electron to the more electronegative nitrogen to form the compound potassium notride
How many valence electrons do transitions elements have?
How many valence electrons do transition elements have?
The elements within a group have a similar number of?
Elements in the same group have the same number of valence electrons. These are the outer-shell electrons that react with other elements.
What is the number of valence electrons for group 2 elements?
Group 2 metals have 2 valence electrons. In fact, the number of valence electrons of elements can be deduced from the group number (e.g. group VII elements have 7 valence electrons).
Valence electrons are involved in what?
Valence electrons are involved in bonding to other atoms.
The transfer or sharing of electrons between elements is called what?
chemical bond formation. Transfer of electron lead to formation of ionic bond and sharing of electron is called as covalent bond
How many valence electrons are transferred from the calcium atom to iodine ine the formation of the compound calcium iodine?
The calcium atom will transfer its two valence electrons, one to each of two iodine atoms, to form the compound calcium iodide, CaI2.
How do you calculate valency of silver nitrate?
Silver Nitrate is a compound. A compound is formed in such a way that its constituent elements share or transfer electrons in order to become stable. So, the valencies are complete. A compound is stable. Only elements have valence electrons.
Where do elements have the same number in valence electrons?
Elements in the same group have the same number of valence electrons.
Are exchanged or shared during the formation of a chemical bond?
They are the electrons in the (outer) valence shell
Where are elements with the same number of valence electrons?
All elements in the same group have the same number of valence electrons.
