valency and atomicity

Remember : When one pair of electrons is shared between the atoms, a single bond is established between the atoms, e.g., H-H and Cl-Cl. When two pairs of electrons are shared, a double bond is established, e.g., O=O. When three pairs of electrons are shared, a tripl..

Valency - It 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 has 4 valence electrons. K LC (6) 2 4 Carbon atom is capable of forming 4 bonds. Hence..

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 val..

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

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; electrons are either given out from the outermost shell, or accepted into the o..

The outermost shell of an atom is known as the valence shell. The electrons present in the valence shell are called valence electron..
