Building materials of a cell are composed of two atoms that form molecules. A chemical bond is created when two atoms share an electron. Also called covalent bond because they share valence electrons. A covalent bond‚ which is the strongest bond‚ takes action when two atoms valence overlap. For example‚ there are two suns and the light that shines from the two solid spheres forms many rays making a radiant cloud around each of the two. If these suns move closer together the radiant shine would

Topic 4 - Bonding 4.1 Ionic bonds 4.1.1 Ionic bond: +ve (cations) and -ve (anions) ions are attracted to each other and form a continuous ionic lattice 4.1.2 Group 1 metals form +1 ions‚ group 2 metals form +2 ions‚ metals in group 3 form +3 ions . Examples : Li+‚ Mg2+‚ Al3+. Greater ease of ionisation Li->Cs is due to the increased electron shielding of the nuclear attraction caused by additional inner shells of electrons. The easier atoms are to ionise‚ the more reactive they

VALENCE BOND THEORY The ‘mixing’ or ‘blending’ of atomic orbitals to accommodate the spatial requirements in a molecule is known as hybridization. Hybridization occurs to minimize electron pair repulsions when atoms are brought together to form molecules. Possible hybridization schemes: 2nd row elements: sp sp2 sp3 3rd row elements also have: dsp3 d2sp3 Each of these hybridzation schemes corresponds to one of the five fundamental VSEPR geometries. Bonding arises from the overlap
