Variation down the group
On moving down the group the number of valence electrons remain the same and therefore all the elements in the group exhibit the same valency..
Example 1
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..
Solution
valence electrons features Valence electrons = 3; core electrons = 10 Valence electrons = 2; core electrons = 10 Valence electrons = 7; core electrons = 10 Valence electrons = 2; core electrons =..
Chemical Bonding
Chemical bonding is like a glue that binds atoms together. And what goes into making that glue? Only electrons. Not all electrons make up the glue, it is only the valence electrons. Valence electrons are the outermost electronsh..
Structure of the Atom
valence electron in the atom Valence Shell and Valence Electron - The outermost shell of an atom is called its Valence shell. It is the decisive shell during a chemical reaction. The electrons of only this outermost shell are involved during chemical combinations; electron..
General Characteristics of Periods
Valence shell electrons : The valence shell electrons increase form one to seven as we move from left to right in a perio..
Variation down the group
The electropositive or metallic character increases down the group because of the increase in the atomic size, which makes it easier to remove the valence electrons..
Cause of Periodicity of Elements
Cause of Periodicity of Elements - The modern periodic table is based on the electronic configuration of the elements. The properties of an element are determined largely by the electrons in its outermost or valence shell. Valence electrons interact..
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 bonds can be explained..
Distinction between the three in terms of energy bands
The electrons in the valence band are not capable of gaining energy from external electric field and hence do not contribute to the current. This band is never empty but may be partially or completely with electrons. On the contrary in the conduction band, electr..
