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 determine the valency of an element, look at its position on the periodic table. Elements in group 1 have a valency of +1, those in group 2 have a valency of +2, group 17 elements have a valency of -1, and group 16 elements have a valency of -2. Transition metals may have variable valencies.
The most common charge (or valency) is -2. But there are compounds formed by elements of group VIA with valency from -2 to +6
The valency for plumbic is +4. This means that plumbic compounds typically have a charge of +4.
Calcium phosphate's formula is Ca3(PO4)2. To find its valency step by step, first find the valency of calcium (Ca) and phosphate (PO4) individually: Calcium (Ca) has a valency of +2. Phosphate (PO4) has a charge of -3, so taking into account the 2 subscript, the total charge of phosphate is -6. Next, balance the charges so that they cancel out: Calcium has a charge of +2, while phosphate has a charge of -6. To balance this, you would need three calcium ions (3 x +2 = +6) for every two phosphate ions (2 x -3 = -6). This results in Ca3(PO4)2. Therefore, the valency of calcium phosphate is 3.
Phosphate typically has a valency of -3, which means it tends to form ionic compounds by acquiring three electrons to achieve a stable octet configuration.
Phosphate has a valency of -3 when it is in its ion form (PO4^3-). It can also form compounds with other elements where the valency can vary depending on the specific compound.

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.
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.
The valency of trioxosulphate IV is 4. This means that it can form four bonds with other atoms in a compound.
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.
