yes.
Fe on the pereodic table means the element Iron
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.
Iron has electron structure [Ar]4s23d6 and thus has 8 valence electrons in theory. For all practical purposes though, Iron shows a maximum valence of 6.
Iron (Fe) is in group 8 on the Periodic Table and it does not have 8 valence electrons. Iron has 2 valence electrons in its 4s orbital and 6 valence electrons in its 3d orbital, making a total of 8 valence electrons.
Fe, or Iron, element 26 belongs to group 8 on the periodic table, although since it is in the transition metals, you cannot rely solely on the group number to find how many valence electrons it has
yes.
Variable valencies are the valencies which can change e.g. Fe (iron) can either have the valency of 2 (Fe II) or 3 (Fe III)
The number of Valence electrons in the groups 3 to 12 is variable, and depends on the element that it is being bonded with.For example:If Iron (Fe) is going to form a compound with Sodium (Na), the Fe will act as though it has 7 valence electrons (i.e. it is willing two accept the one Na Valence electron).

Iron has variable valence. It can be either 2 or 3.
because they have one valence electron
