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.
What is the valency of gold?
the valence of gold is 3+
What the valency for silver?
The valency of silver is typically +1. However, silver can also exhibit a valency of +2 in certain compounds.
What is the symbol and valency for gold?
The chemical symbol for gold is Au, and its valency is typically +1 or +3.
What is the valency for copper?
The valency of copper can vary. Copper is a transition metal and can exhibit valencies of +1 or +2, depending on the compound it forms.

Why transition elements show variable valency?
Transition elements contain 2 outermost shells incompleted including the valence shell. But when it reacts with other, it shares,gives or accepts elctrons from its inner shells.

The chemical symbol for gold is Au, and its valency is typically +1 or +3.
What do you mean by variable valency?
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)
Why does Scandium have no variable valency?
Scandium has no variable valency because it has a relatively simple electron configuration, with only one electron in its outermost shell (3s² 3p¹). As it primarily exhibits a +3 oxidation state, it tends to lose these three valence electrons without forming other stable oxidation states. The absence of d-electrons in its valence shell limits the ability to form multiple oxidation states, making its chemistry straightforward compared to transition metals, which often exhibit variable valency due to the involvement of d-orbitals.
Why some elements have variable valencies?
Certain elements combine with other atoms, donating, accepting or sharing electrons in different proportions depending on the nature of the reaction. For example, iron combines with oxygen to form ferrous oxide as well as ferric oxide. In the formation of ferrous oxide, iron exhibits a valency of +2, whereas in ferric oxide, it has a valency of +3. This is termed variable valency
What is the valency for copper?
The valency of copper can vary. Copper is a transition metal and can exhibit valencies of +1 or +2, depending on the compound it forms.

yo dawg i heard you like exhibits so we put xzibit in yo exhibit so you can lookat xzibit while you exhibit xzibit in yo exhibit
Does oxygen exihibit variable valency?
it does. for example in H2O oxygen has a valency 2 while in hydrogen peroxide H2O2 oxygen exhibits valency 1
What is valency iron?
Iron has variable valence. It can be either 2 or 3.
