a compound.
You can not predict whether an isotope nucleus is likely to be stable. There is a lack of electrons in the nucleus creating a chemical change in the atom becoming stable.
Bonds, radiation...
four single bonds
It depends on the hybridization of the central atom.
Two oxygen atoms combine to form a molecule by sharing electrons
the amount of electrons available on the outer shells of the atoms
2
the presence or absence of double bonds between the carbon atom and other atoms
Nitrogen appears as N2 where there are three bonds between the two nitrogen atoms.
an atom's outer energy level doesn't have the maximum number of electrons
Covalent bonds between a hydrogen atom and an oxygen atom.
An atom that has fewer than 8 valence electrons is more reactive, or more likely to form bonds, than an atom with 8 valence electron. Atoms bond by gaining, losing, or sharing electrons in order to have a filled outermost energy level with 8 valence electrons.
an atom's outer energy level doesn't have the maximum number of electrons.
a compound.
hyrdrogen bonds.
There is none because there are no bonds in an atom.
