Transition metals
Mostly elements of the picrogen family and the transition element group have varying valency. For eg. of the picrogen; Nitrogens have 3, 5 valency. As for the transition elements as of Iron (ferrum) has 2, 3 valency
Group 3 to 12 have varying numbers of valence electrons. These groups are for transition elements on the Periodic Table.
metals (except group 1 and group 2 elements) have various oxidation states (or valency)
The Transition Metals
For example the group 6.
There is no set amount of valence electrons for nonmetals. The amount of valence electrons a nonmetal has is determined by the number of electrons on the outer shell of the atom.
Nonmetals attract electrons.
The Elements have a different Total Number of Electrons, but the same number of Valence Electrons.
Elements in the same group have the same number of valence electrons. These are the outer-shell electrons that react with other elements.
Elements in the same group have the same number of valence electrons.
There is no set amount of valence electrons for nonmetals. The amount of valence electrons a nonmetal has is determined by the number of electrons on the outer shell of the atom.
hydrogen and helium
Yes, nonmetals generally gain electrons to fill valence shells.
metals can conduct electricity, the valence electrons of nonmetals cannot roam freely
Nonmetals attract electrons.
They have different numbers of valence electrons.
They have different numbers of valence electrons.

The Elements have a different Total Number of Electrons, but the same number of Valence Electrons.
That depends on the element in question. Atoms can have anywhere from 1 to 8 valence electrons. For the main group elements, Groups 1,2,13-18, the number of valence electrons are the number in the one's place in their group number, as follows: Group 1 Elements: 1 valence electron Group 2 Elements: 2 valence electrons Group 13 Elements: 3 valence electrons Group 14 Elements: 4 valence electrons Group 15 Elements: 5 valence electrons Group 16 Elements: 6 valence electrons Group 17 Elements: 7 valence electrons Group 18 Elements: 8 valence electrons The transition metals, Groups 3 - 12, are more complicated because they are adding d electrons, some of which behave like valence electrons, and many transition metals can have different numbers of valence electrons. For example manganese can have anywhere from 2 to 7 valence electrons.
How many valence electrons do transition elements have?
Elements in the same group have the same number of valence electrons. These are the outer-shell electrons that react with other elements.
