valence electrons

General Characteristics of Periods - 1. Valence shell electrons The valence shell electrons increase form one to seven as we move from left to right in a period. 2. Valency The valency of the elements with respect to hydrogen, increases fo..

Chemical Combination - The force which holds together the ions, atoms and molecules in a chemical substance is called as chemical bond. It is the same force which makes substances combine with each other in many different ways to give newer products. The combining tendency of atoms to form chemical..

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 atom..

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 increases on going down the group. The chemistr..

Classify the following elements as metals or non-metals based on valence electrons..

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 valence electrons belonging t..

0 - 8 : 2, 6Valency = 8 - Number of valence electrons= 8 - 6= 2 If the outermost shell of an atom is completely filled, its valency = 0. The outermost shells of the noble gases helium, neon, argon, krypton etc. are completely filled. Hence their valencyh..

Representative elements are those elements whose inner shells are complete and whose outer shell (valency shell) has 1 to 7 electrons. They are also called normal elemen..
