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...
structure. nacl has four cations and four anions in a face-centered cubic unit cell. since there are 4 atoms or ions present in each unit cell of a face centred cubic structure, therefore, the number of nacl units in a unit cell of nacl is four. the cubic unit cell of nacl can be...
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 aquantummechanical phenomenon calledresonance. At this stage, resonance can be regarded as a blending process that spreads double-bond charact...
