WebA molecule is defined as the smallest unit of a compound that contains the chemical properties of the compound. Molecules are made up of groups of atoms. Describing the … WebGenerally, the electrons are either added to or lost from the valence shell of an atom; the inner-shell electrons are more tightly bound to the positively charged nucleus and so do not participate in this type of chemical interaction. Ionization generally involves a transfer of electrons between atoms or molecules.

Web8 de mar. de 2024 · The regularity of the crystal reflects the fact that the atoms (or, more generally, the molecules) are all alike, so the minimum potential energy arrangement of one group is the same as for another group. So one can expect the least potential energy when the whole crystal is perfect.
