The valency of an element measures its ability to combine with other elements. This valency is determined by the number of electrons in the outer shell of each atom of an element.
PO4^-3 is an ion.So its valency is -3

To find the valency of nitrogen in NH4+, you need to consider the overall charge of the ammonium ion, which is +1. Since there are four hydrogen atoms each with a valency of +1, the nitrogen atom must have a valency of -3 to balance out the charge of +1 on the ion. Therefore, the valency of nitrogen in NH4+ is -3.
To find the valency of a mixture or compound, you need to know the individual valencies of the elements involved. Valency is determined by the number of electrons an atom gains, loses, or shares to achieve a stable electron configuration. For example, in water (H2O), hydrogen has a valency of +1 and oxygen has a valency of -2, resulting in a compound with a total valency of zero.
To find the valency number of an element, look at the group number on the periodic table. For main group elements (groups 1, 2, 13-18), the valency is the same as the group number. For transition metals, the valency can vary and is usually determined by the charge of the ion formed by the element.
it is the stupidest compound whos valency is really difficult to find
The number of electrons in the outermost energy shell is usually used in finding the valency of a given element. For instance elements that have two electrons in the outermost energy shell have valency 2.
by knowing the no. of electorns in its outermost shell
The valency of manganese can be determined by looking at its electron configuration. Manganese typically forms compounds in which it has a valency of +2, +3, +4, +6, or +7 depending on the specific compound it forms. This valency corresponds to the number of electrons that manganese can lose or gain to achieve a stable electron configuration.
Valency is calculated in this way... 1. Find atm no of that element. 2. Write down electronic configuration. 3. Take the valence shell electron number. 4. The number of electrons to be lost are added as the valency.
The valency of lithium is 1. It has one valence electron in its outer shell.
