Molar mass calculations are explained and there is a JavaScript calculator to aid calculations. Periodic Table of Elements Provides comprehensive data for each element of the periodic table of elements including
Covalent bonding: A covalent bond is formed by sharing of electrons (equally or partially polarized) between the two non-metals. Octet rule:By obtaining eight electrons around the valence shell of an element, then compound satisfied the octet rule and thus, achi...
The Lewis Structure for the Salt NaCl depicts two ions with complete octets in their outer shells of electrons. As a result, there is a positive charge on sodium (due to one lost electron) and a negative charge on chlorine (due to one electron gained).
In such cases, the actual Lewis structure is regarded as a blend of these contributions and is written: The blending together of these structures is actually a quantum mechanical phenomenon called resonance. At this stage, resonance can be regarded as a blending process that spreads double-bond ...
