Document Summary

Covalent bond: a bond formed by sharing electrons between atoms. Molecule : a group of atoms held together by covalent bonds. I. e hydrogen has suborbital of s, therefore h 2 has overlap of the 1s orbitals, the two electrons are shared providing 1s 2 configuration of helium forces. Bond length: the optimum distance between nuclei as a result of attractive and repulsive. Molecular compound : a compound that consists of molecules rather than ions. * elements in the third row and below in the periodic table have vacant d orbitals that can be used for bonding, allowing the to have an expanded octet (i. e phosphorus" vacant 3d orbital pcl 5 has 10 valence electrons) Hbr ? 1, since each only need one more electron. Pbr ? 3, since p forms three bonds. Coordinate covalent bond: the covalent bond that forms when both electrons are denoted by the same atom.
