How will you find the valency of Cl S and magnesium?

As magnesium has 2 valence electron, its valency is 2. Accordingly, the valency of chlorine is 7-8 which is -1. Thus the valency of Mg is 2, whereas for chlorine it is -1 in MgCl2.

How will you find the valency of chlorine sulphur and magnesium by BYJU’s?

Answer: The definite combining capacity of the atoms of each element, wherein electrons are lost, gained or shared to make the octet of electrons present in the outermost shell is defined as valency.

How will u find the valency of chlorine?

The electronic configuration of chlorine is [Ne]3s2 3p5or can also be written as 2,8,7. This shows chlorine has 7 valence electrons in its outermost shell. Accordingly, the valency of chlorine is 7-8 which is 1.

How will you find the valency of sulphur?

The electronic configuration of sulfur is (S) [Ne] 3s1 . So in order to achieve stability, sulfur has to gain 2 electrons. Therefore, the valency of sulphur is 2. Few sulphur compounds such as so2, SO3, etc, have a valency of 6.

How will you find the valency of chlorine sulphur and magnesium Brainly?

If the number of electrons in the outermost shell of the atom of an element is less than or equal to 4, then the valency of the element is equal to the number of electrons in the outermost shell. The distribution of electrons in chlorine, sulphur, and magnesium atoms are 2, 8, 7; 2, 8, 6 and 2, 8, 2 respectively.

How will you find the valency of sulphur and chlorine?

Hence, the valency of Sulphur is 2. In the same way, the electronic configuration of Chlorine is 2,8,7. Thus, Chlorine has 7 valence electrons. Thus, its valency is 8-7 = 1.

How will you find the valency of chlorine sulphur and magnesium Vedantu?

A magnesium atom has 2 electrons in its outermost shell (M shell). It can lose its 2 outermost electrons to achieve the inert gas electron configuration. So its valency is 2. Therefore, the valency of chlorine, sulphur and magnesium is 1, 2 and 2 respectively.

What is the valency of magnesium?

2^+
Magnesium has valency equal to 2^+ because the electronic configuration of Mg is [2,8,2]. The nearest noble gas to magnesium is neon with electronic configuration of [2,8], to achieve this stable electronic configuration Mg can lose 2 valence electrons, hence its valency is 2^+ .

What is valency of sulphur in SO2 and SO3?

If we talk about sulphur, it has vacant d-orbitals to accommodate electrons. That is the reason why in sulphur dioxide it shows +4 valency and in sulphur trioxide it shows +6 valency.

What is the valency of chlorine Sulphur magnesium and phosphorus?
