a compound can be made out of 2 or more elements
A compound can only consistent of at least two different elements.
The number of elements in a compound depends on the compound in question. For example, water is a compound, H2O and it contains TWO different elements; hydrogen (H) and oxygen (O). Another compound would be ammonium hydroxide, NH4OH and it contains THREE different elements; nitrogen (N), hydrogen (H), and oxygen (O).
Elements of group 18 are least reactive.These are noble gases.They are unlikely to have a reaction with any element or compound.
A compound consists of at least two elements chemically bonded together.
A compound forms when two or more different elements chemically bond together. Therefore, at least two elements must be present for a compound to form.
A compound must have at least two atoms of different elements.

A compound can only consistent of at least two different elements.
Part of the definition of a compound is that it must contain atoms of at least two distinct elements.
The number of elements in a compound depends on the compound in question. For example, water is a compound, H2O and it contains TWO different elements; hydrogen (H) and oxygen (O).

2 elements
Yes: compounds have to consist of at least two different elements.
Yes, a compound is a substance composed of two or more elements that are chemically bonded together in a fixed ratio.
Elements of group 18 are least reactive.These are noble gases.They are unlikely to have a reaction with any element or compound.
At least one. (That's not, entirely, a smart-aleck answer. I suspect you don't understand the meaning of either element or compound or possibly both. You need some review study, and trying to figure out how "one" is a legitimate answer should provide that. As a hint, consider the diatomic gasses, or buckminsterfullerene.)
