: 1. The elements present in same group have same number of valence electrons. 2. The total number of electron present in the valence shell of the representative elements indicates its group number. 3. The electrons are added across a period to the ..

Question: Explain why the electron affinity of fluorine is less than that of chlorine though fluorine precedes chlorine in group VIIA. Answer: Fluorine is a smaller atom compared to chlorine. The 7 valence electrons in fluo..

Main Features of the Long Form of the Periodic Table - 1. The properties of an element in the periodic table mainly depend on its outer electronic configuration, except in the case of transition elements. 2. Each period begins with an element having only one electron in the ..

General Characteristics of Group - 1. Valence shell electrons On moving down the group the valence shell electrons remain the same. 2. Valency The valency of all the members of a particular group is same. 3. Properties of elements The memb..

(a) Valence electrons = 3; core electrons = 10(b) Valence electrons = 2; core electrons = 10(c) Valence electrons = 7; core electrons = 10(d) Valence electrons = 2; core electrons..

Oxidation States - Halogens have only one electron less than the next noble gas. Therefore, they can get the noble gas configuration either by gaining one electron to form uninegative ion, X - , or by sharing electrons with other atoms. Thus, they show an oxidation of ..

What is the number of valence electrons, valency and valence shell of the atom whose atomic number is 17? K, L, M Electron configuration : 2, 8, 7 Number of valence electrons = 7 Valency = 8 - 7 = 1 Valence s..

A - 2, 8, 2 - It is a metal as it has 2 valence electronsB - 2, 8, 6 - It is a non-metal as it has 6 valence electronsC - 2, 6 - It is a non-metal as it has 6 valence electrons..
