A chemical bond is the energy that holds two atoms together in a compound. This energy can be farther broken down into ionic bonding and covalent bonding. An ionic bond is a chemical bond characterized by attractive force between ions of opposite charge. The formation of an ionic bond involves a complete transportation of negatrons between atoms. and can be predicted when one atom has a much higher electronegativity than the other. A covalent bond is a really strong chemical bond formed by the sharing of negatrons. Multiple covalent bonds can be formed when multiple braces of negatrons are shared between atoms. Covalent bonds are by and large characterized in two types. polar and non-polar covalent bonds.
Electronegativity is a comparative step of the attractive force that atoms of an component have for negatrons. The higher the electronegativity of an atom. the stronger its attractive force will be for negatrons. The type of bond formed between two atoms ( ionic or covalent ) can be predicted by the difference in electronegativities of the two bonding atoms.
Molecular Geometry is the overall agreement of the atoms in a molecule. The bonded atoms in a molecule are responsible for finding the molecular geometry of a system. Non-bonded negatron braces are non considered in finding molecular geometry. The molecular geometry consists of six different forms. Linear. rhombohedral planar. tetrahedral. rhombohedral pyramidal. rhombohedral bipyramidal. and octahedral.
Melting point. boiling point. and vapor force per unit area are related to the strength of attractive forces between molecules. These attractive forces are called Intermolecular Forces. There are three types of intermolecular forces: ionic. dipole-dipole. and H bonding. In ionic bonding antonym charges attract each other. ionic forces besides hold many ions in a crystal lattice construction.
Polar covalent molecules are sometimes described as “dipoles” . significance that the molecule has two “poles” . One terminal of the molecule has a partial positive charge while the other terminal has a partial negative charge. The H bond is truly a type of dipole forces. A H bond is the attractive force between the H attached to an negatively charged atom of one molecule and an negatively charged atom of a different molecule. Normally the negatively charged atom is oxygen. N. or F.
