Which group of elements can have varying numbers of valence electrons metals noble gases non-metals?
Transition metals
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 the properties of groups 3 through 12 compare with the elements left and right of the transition metals?
Elements from Group 3 to 12 are called Transition Elements. These elements are heavy metals. They lie between the strongly eloctropositive elements to their right and the electronegative elements ( non-metals) to their left.These metals mainly have 2 valence electronswith the metallic character decreasing from left to right of their period.
Valency of phosphorous?
-3 to metals and hydrogen (phophide) +3 in oxo-compounds (phosphite) +5 in oxo-compounds (phosphate)
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)
What non-metals has no variable valency Zn Cu Fe N?
Zinc (Zn) does not have variable valency
How do you find out valency of manganese?
Manganese is a transition element and has a variable valency but generally has a valency of 2 and exists as Mn2+
What is the valency of trioxide?
S = +6 valency O = -2 valency
How are halogens like metals?
Halogens are not like metals. Halogens are elements missing one electron for full 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 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.
Valency of phosphorous?
-3 to metals and hydrogen (phophide) +3 in oxo-compounds (phosphite) +5 in oxo-compounds (phosphate)
