valence electrons

Classify the following elements as metals or non-metals: A - 2,8,2 - It is a metal as it has 2 valence electrons B - 2,8,6 - It is a non-metal as it has 6 valence electrons C - 2,6 - It is a non-metal as it has 6 valence electrons The..

When a complete transfer of one or more valence electrons from the atom of a metal to that of a non-metal takes place, an ionic (or electrovalent) bond is formed. As a result of this electron transfer following changes occur in the reacting atom..

The hardness of metals is due to the strength of the metallic bond. In general, the strength of a metallic bond depends upon: The greater the number of valence electrons for delocalisation the stronger is the metallic bond. Smaller the size of the kernel of metal atom, gre..

All isotopes of an element have the same number of valence electrons thus have identical chemical properties. The physical properties of the isotopes are different due to the difference in the number of neutrons in their nuclei. The densities, melting points and boiling poi..

The compounds of the alkali metals are ionic in nature. Alkali metals form cations readily by losing the valence electrons (due to the low ionization energies and large atomic sizes). They go on to form ionic bonds with the non-metals of the 'p' bloc..

Chemical Properties of Alkaline Earth Metals - As alkaline Earth metals have low ionization energies and high electropositive character, they are very reactive and have a strong tendency to lose valence electrons, though less than alkali metals. The reactivity of these elements ..

Representative or Main Group Elements - These consist of all 's' and 'p' block elements excluding the noble gases (group 18 elements). The chemical properties of the representative elements are determined by the number of valence electrons in their atoms. The number of vale..

Members of the same group have similar electronic configuration of the valence shell and thus show same valency..
