Dysprosium, gold, Promethium
To determine which category contains the least elements, one would need to compare the number of elements in each category directly. Without specific categories or data provided, it is impossible to identify the category with the least elements. If you provide more context or the categories in question, I can offer a more precise answer.
It nonmetal ! I know this one! I had it on a worksheet!
All the oxy acids contain 1-hydrogen, 2-oxygen and 3- a non metallic element as Sulphur, Nitrogen, Phosphorus, Carbon, silicon, Boron e.t.c.
Yes, all matter on earth contains at least one element, and all elements are found in the periodic table.
An alloy contains at least one metallic element. Alloying involves mixing a metal with one or more other elements to enhance its properties, such as strength or corrosion resistance.
Reaction between a metal oxide and a nonmetal oxide to produce a salt containing at least three elements is a synthesis reaction. The salt almost always contains at least one monatomic metal cation and at least one polyatomic anion that contains all of the elements of the reacted nonmetal oxide plus the oxygen atoms from the metal oxide. This type of anion is called an "oxyanion" or the "anion of an oxyacid."

If it is composed of a metal and a nonmetal, then it will most likely be an ionic compound.
Group 4 (Now 14) of the Periodic Table contains only one non-metal; Carbon (C). All the rest of the elements in this group are metals. The metals in Group 4(14) are;SiliconGermaniumTinLead
At least two: oxygen and at least one other.

One component of a binary ionic compound is a metal element.
Yes, all matter on earth contains at least one element, and all elements are found in the periodic table.
If a compound contains at least one metal atom and at least one nonmetal atom, the compound is ionic. Na (Sodium) is a metal. Br (Bromine) is a nonmetal. Therefore, the compound NaBr is ionic.
A line contains at least 2 points.
