PO4^-3 is an ion.So its valency 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.
by knowing the no. of electorns in its outermost shell
Group number 1 = Valency 1+group number 2 = valency 2+group number 3 = valency 3+group number 4 = valency 4+ and 4- (some cases) group number 5 = valency 3-group number 6 = valency 2-group number 7 = valency 1-group number 8 = valency 0For the transition elements they will either state Copper (III) Sulphate or it will be like Cu2(SO4)3You can find the valency by the base of sulphate and you know its positive because metals are always positive and are written in the left.Source: I am a GCE O Level Sciences Student (O2)
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.
PO4 has its valency 3 but, PO3 also has its valency 3
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 sodium phosphate is determined by the charges of the individual ions in the compound. Sodium (Na) is a group 1 element with a valency of +1, while phosphate (PO4) has a charge of -3. To balance the charges in the compound, three sodium ions (each with a valency of +1) are needed for every one phosphate ion (with a valency of -3). Therefore, the valency of sodium phosphate is +1 for sodium and -3 for phosphate.

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.
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.
