valence metals

Hydrogen generally shows + 1 valency like alkali metals..

Metals have 1 to 3 electrons in the outermost shell of their atom..

Normally metals donate electrons from their valence shell so as to form positively charged ions such that the charge on the ion is equal to its electropositive valency..

Besides the above reactions of chlorine with metals, chlorine also undergoes addition reactions with heated metals like aluminium, zinc, iron, etc. to form their chlorides. Metals with variable valencies always form the chloride of the higher metallic..

Valence electrons of an atom are responsible for chemical reactions as they take part in them. Elements having same number of valence electrons in their atoms possess similar chemical properties. All alkali metals have one valence electron in their atom...

The metal ligand bond arises by donation of pair of electrons by ligands to the central metal ato..

Group IA, IIA and IIIA consists of metals of normal elements. They have 1, 2, or 3 valence electrons which they can easily donate to acquire the configuration of nearest noble gas. They become positively charged i.e., cations. ..

Periodic Table and Valency of Elements - a) Group IA, IIA and IIIA consists of metals of normal elements. They have 1, 2, or 3 valence electrons which they can easily donate to acquire the configuration of nearest noble gas. They become positively charged i.e., cations..

The suffix ' ous ' is attached at the end of the name of the metal with lower valency. Suffix ' ic ' is attached at the end of the metal with higher valency..

fig 2.34 - Metal deficiency defect due to missing of a cation of lower valency and presence of a cation of higher valency Occurs when metals show variable valency. Example: Transition elements It occurs due to the missing of a cation from its l..
