Metals form ionic compounds when the metal atom donates electrons to the non-metallic atom. When two non-metals coine they form a molecular compound as the bond is formed by the sharing of electrons (covalent). As there is a trend from metal to non

Why transition metals and their compounds are act as alyst? Transition metals and their compounds are known to act as good alyst due to the following reasons: (1) Due to the variable oxidation state, they form unstable intermediate compounds and provide a new path with lower activation energy for the reaction (Intermediate compound formation theory) and hence rate of …

Metals have properties suited to a wide range of uses. They are characteristically shiny, and most are malleable, ductile, dense, very good electrical conductors and have high melting points. Malleability is the ability of a material to deform when compressed – gold is very malleable and can be beaten to an extremely thin sheet.

Highly reactive metals such as sodium, calcium, aluminium, etc., are sometimes used as reducing agents because they can displace metals of lower reactivity from their compounds. For example, when manganese dioxide is heated with aluminium powder, manganese dioxide is reduced to metallic manganese while aluminium gets oxidized to aluminium trioxide.
What Are Ionic Compounds? (with pictures) - wiseGEEK
2020/7/20· In their natural form, ionic compounds are never strictly ionic or neutral in charge, and often have some degree of covalency — the sharing of electrons between different atomic energy shells. Electronegativity affects how strong the negative charge is in ionic compounds, with the Pauling scale rating fluorine as the most electronegative element at a rating of 4.0.
