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 0
For the transition elements they will either state Copper (III) Sulphate or it will be like Cu2(SO4)3
You 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.

What elements in an element family have similar?
Valency
What is the valency of the last element in the 3rd group of modern periodic table?
The last element in the 3rd group of the modern periodic table is gallium, with the symbol Ga. Gallium has a valency of +3, meaning it tends to lose three electrons to achieve a stable electron configuration.
What is the valency of 31st element?
The 31st element is Gallium (Ga) with an atomic number of 31. Gallium commonly exhibits a valency of +3 in chemical compounds due to the three valence electrons in its outer shell.
What is the formula for valency?
The valency of an element is determined by the number of electrons it gains, loses, or shares to achieve a stable electron configuration. It is typically the same as the number of electrons an element needs to gain or lose to achieve a full outer shell (octet). For example, elements in Group 1 have a valency of +1 because they lose one electron to achieve stability, while elements in Group 17 have a valency of -1 because they gain one electron to achieve stability.
What is the valency of the smallest element?
the smallest element is hydrogen of which its valency is one.
How do you find valency?
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.
Which element has 4 and 6 valency?
Carbon has a valency of 4, while sulfur has a valency of 6.
What is the meaning of valency?
Valency (in chemistry) is the number of the valence bonds of a chemical element.
How calculate valency?
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.
What is bivalent ions?
an element which has valency 2
What is the highest valency element?
The highest valency element is oxygen, with a valency of 2. The valency of an element represents the number of bonds it can form with other elements. Oxygen typically forms bonds by gaining two electrons to achieve a stable electron configuration.
What the valency of So2 and So3?
The valency of SO2 is 4, while the valency of SO3 is 6. The valency of an atom is the combining power of an element, which indicates the number of bonds it can form with other elements.
Which element has least valency?
The noble gases have the least valency which is zero. It is because thay have a complete shells.
What is the valency of an element sodium chloride?
Sodium chloride is composed of sodium (Na) and chlorine (Cl). Sodium has a valency of +1, while chlorine has a valency of -1. In sodium chloride, sodium donates its electron to chlorine, forming an ionic bond with a valency of +1 for sodium and -1 for chlorine.
Can an element have more than one valency?
