Calcium's valency is 2.
neither 3 nor 5, actually the difference of the two; that is 2.

Radical - positive and negative radical in chemistry?
Valency is the number of hydrogen atoms that can combine with [or displace] one atom of the element [or radical] to form a compound. For example, one atom of hydrogen combines with one atom of chlorine to form hydrogen chloride [HCl]; so, the valency of chlorine [chloride] is one. Similarly, the valency of the nitrate radical [NO3] in the compound nitric acid [HNO3] is 1, and the valency of the sulfate radical in the compound sulfuric acid [H2SO4] is 2. For elements that do not combine with hydrogen, the valency is the combining power of the element with another element whose valency is known. Valency may also be defined as the number of electrons that an atom donates or accepts to form the duplet state (i.e., 2 electrons in outermost shell) or octet state (i.e., 8 electrons in outermost shell). The valency of an element [or radical] is always a whole number. Elements [or radicals] with valency one are monovalent, those with valency two are divalent, and those with valency three are trivalent
Does chlorine has positive or negative valency?
Negative.
Which has valency equal to zero?
The noble gases.
Cube route of 90?
Each one of a cube's vertices has a valency of 3. The graph of its edges is therefore non-Eulerian and so it is not possible to have a cube route.
What is the valency of nitrogen in chain and cyclic ring?

What is the valency of nitrogen?
It has 3 as its valency.3
Why does periodic table show phosphate having valency of 5 yet it is really valency 3?
You have mistaken Phosphate for Phosphorus. Phosphorus is in Group 5 of the periodic table. Group 5 elements generally have a valency of 3, but it is also possible for them to have a valency of 5... Below are two examples of compounds, one using Phosphorus with valency 5 (V) and one using Phosphorus valency 3 (III) : Phosphate (phosphorus with maximum oxygen) This is formed by Phosphorus (V) + 4 Oxygen. Oxygen has valency -2, thus... 5 + 4 x -2 = 5 - 8 = -3 So we can see that Phosphate has a charge of -3 (or in other words a valency of 3) Phosphite (phosphorus with one less than maximum oxygen) This is formed by Phosphorus (III) + 3 Oxygen, and so... 3 + 3 x -2 = 3 - 6 = -3 So we can see that Phosphite also has a valency of 3 Hope this helps!

What is the valency of boron?
the valency of boron is -3
How to find valency of PO4?
PO4^-3 is an ion.So its valency is -3
