Chemical similarity (or molecular similarity) refers to the similarity of chemical elements, molecules or chemical compounds with respect to either structural or functional qualities, i.e. the effect that the chemical compound has on reaction partners in inorganic or biological settings.
Li is the only group 1 element which forms a stable nitride, Li 3 N. [4] Mg, as well as other group 2 elements, also form nitrides. [4] Lithium carbonate, phosphate and fluoride are sparingly soluble in water. The corresponding group 2 salts are insoluble. (Think lattice and solvation energies). Both Li and Mg form covalent organometallic ...
A period 3 element is one of the chemical elements in the third row (or period) of the periodic table of the chemical elements.The periodic table is laid out in rows to illustrate recurring (periodic) trends in the chemical behavior of the elements as their atomic number increases: a new row is begun when chemical behavior begins to repeat, meaning that elements with similar behavior fall into ...
Analogy is a comparison or correspondence between two things (or two groups of things) because of a third element that they are considered to share. [1]In logic, it is an inference or an argument from one particular to another particular, as opposed to deduction, induction, and abduction.
[1] [2] This can be the length of a carbon chain, [2] for example in the straight-chained alkanes (paraffins), or it could be the number of monomers in a homopolymer such as amylose. [3] A homologue (also spelled as homolog ) is a compound belonging to a homologous series.
