Valence Electrons - The outermost shell of an atom is known as the valence shell. The electrons present in the valence shell are called valence electrons. K L M Na - 11 - 2 8 1 Valence shell - M ..

Valency - Valency is the combining capacity of an atom. It is equal to the number of electrons the atom loses, or gains or shares when it combines with one or more atoms. Depending on whether the atom loses, gains or shares electrons, the valen..

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 ..

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

Like halogens, hydrogen may also show 1 valency by accepting an electron. Example: NaH (Sodium hydrid..

Valency is the combining capacity of an element. It is the number of electrons in an atom that actually take part in bond formation. For example, carbon atom with an atomic number 6 has 4 valence electrons.K LC 6 2 4Carbon atom is capable of forming..

Valency is the combining capacity of an atom. It is equal to the number of electrons the atom loses, or gains or shares when it combines with one or more atoms. Depending on whether the atom loses, gains or shares electrons, the valency ..

Variable Valency - 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. However, in transition elements, an atom loses electrons from..

Introduction - Elements of group 13 to 18 of the periodic table are collectively called 'p' block elements. The general electronic configuration of these elements is ns 2 np 1 - 6 . They involve the filling up of 'p' orbitals of their outermost shel..

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. ..
