what is the difference between valency and valence electron? Pl. explain with examples.

 valency = combining capacity of an atom expressed as the no. of single bondsthe atom can form or the no. of electrons an element gives up or accepts when reacting to form a compound.

valence electrons electrons in the outermost atomic orbitals of an atom that can take part in forming bonds with other atoms to form molecule

In cyclo hexano noxime , the nitrogen atom has three valence bonds and by the first definition it has a valence of three. Nitrogen has five valence electrons thus it has a valence of five, because it can form maximal five valence bonds, as in N-methyl-1-phenylmethanimine oxide. In cyclohexanonoxime, nitrogen has the oxidation state −1 and oxygen −2.

Valency is the number of electron which can be accepted or can be given to other atom. and valence electrons are the electrons in the last shell or energy level of an atom that are shared or participate in the bonding.

ohh i m just late......anyway thumbs up to u

ur ans is better

 no i think it ws posted at the time.. nd thanxx :)))

 at the same time i mean

.

time shown is same but ur ans is above me so it's first one...

time shown is same but ur ans is above me so it's first one...time in seconds is same but in milli second u r faster.....

anyway i m going offline now byeee

so lateeeeeeeee

 hmm byeee
