Question

please explain me the difference between valency an and atomicity reffering to the lines I have marked​

Answer 1

Answer:

valency=the combining of power of an element especially as measured by the number of hydrogen atoms it can displace  or combine

                                                                                              the valence and velocity of its combining power with other power atoms when it forms chemocal compounds or molecules

Answer 2

Answer:

Explanation

1. Atomicity is the number of atoms present in a molecule.
2. Valency is the maximum number of electrons that an atom has to lose, gain or share in order to get stabilized.
3. The main difference between atomicity and valency is that atomicity explains a molecular property whereas valency describes an elemental property.
