chemical bonds?

Question

what is the major factor in determining the type of bond that would form between two atoms or compounds? please explain.

Answer 1

The nature of the bond depends upon what happens to the electrons in the bond. The chemical bond is only between two atoms. Two or more atoms can form molecules.

If one atom transfers an electron to another atom, the "giver" becomes positively changed and the "receiver" becomes negative. The interaction between the charged atoms keeps them together and this is called an ionic bond. This is like for NaCl.

If two atoms share the bonding electrons equally, and neither has them more than the other, then this is called a covalent bond. This is typical of C-C bonds.

The type of bond which lies in the middle is sharing the two electrons, but one tend to hold then tighter than the other. A good example is water H-O-H, where the electrons in each H-O bond are shared but oxygen holds them closer then the hydrogens do, This is called a polar covalent bond.

Answer 2

For atoms to bond together, they share electrons.
If the electrons are equally shared it's known as a covalent bond.
The extent to which the electrons are shared between atoms, are given number values, known as Electronegative values. Each atom has it's own electronegative value.
If I remember right, if the different between the values of two atoms is greater then 1∙7, then the bond is considered ironic.
It the bond is ironic, it simply means one of the atoms predominately has a greater share of the bonding electrons for the majority of the time.

Answer 3

It's availability of free electrons and stability of atom or compounds(when bonds form). When chemical bonds form atom's energy drops lower(become more stable) then when it doesn't have bonds. Available electrons on outeredge of atoms will rearrange to form bonds (single, double, triple...etc) that lead to lowest energy in general.
