What is atomic valence? |
| Answer» The combining capacity of an atom is known as its valency. The number of bonds that an atom can form as part of a compound is expressed by the valency of the element.As we know, the number of electrons in the outermost shell of hydrogen is 1, and in\xa0magnesium,\xa0it is 2. Therefore, the valency of hydrogen is 1 as it can easily lose 1 electron and become stable. On the other hand, that\xa0of magnesium is 2 as it can lose 2 electrons easily and also attain stability. | |
