How do you identify valency of any atom?
The easiest way to determine the valency of an atom is to locate its place on the periodic table. Generally, it is useful to remember that metals tend to give away valence electrons where non metal atoms tend to obtain them. For example, sodium, a metal, is in group 1 has valency of 1. Sulfur, a non metal, is in group 16 and is 2 electrons away from its stable electron configuration, hence it has valency of 2.
How do you take out valency an element?
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)
Which group of elements can have varying numbers of valence electrons metals noble gases non-metals?
Transition metals
Valency of phosphorous?
-3 to metals and hydrogen (phophide) +3 in oxo-compounds (phosphite) +5 in oxo-compounds (phosphate)
What does the electron in the outer most level determine?
It is generally called the valence electron as it determines the valency of electrons.
What non-metals has no variable valency Zn Cu Fe N?
Out of the non-metals you listed, nitrogen (N) is the only one that does not exhibit variable valency. Zinc (Zn), copper (Cu), and iron (Fe) can exhibit variable valency in certain compounds.
How are halogens like metals?
Halogens are not like metals. Halogens are elements missing one electron for full valency.

What is the valency of trioxide?
S = +6 valency O = -2 valency
What does ni and tc perdioc table have in common?
Both are transition metals and have a valency of 2.
What kind of elements exibit variable vaiency?
Many metals, non-metals and semi-metals have variable valency= Eg= Metals = Iron(2,3) Manganese(2,4) Copper(1,2) Non-Metal = Sulfur(4,6) Carbon(2,4) Phosphorus(3,5) Semi-Metal= Silicon(2,4) Arsenic(3,5) Germanium(2,4)
What is the valency of a sulphate ion?
The valency of a sulfate ion is -2, meaning it has a charge of -2 due to the presence of four oxygen atoms and a sulfur atom. This valency allows the sulfate ion to form compounds with metals and other ions through ionic bonding.
How do find valency number?
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.

What kind of atoms gain electrons?
Generally non-metals gain electrons and form anions.
Why do elements in th alkali metals group often form iconic bonds with the halogen group?
Alkali metals have one electron in their valency shell whereas halogens have seven. By losing al electron to a halogen, both ions get a full set of electrons in their valency shell.
