what happens when a mixture is formed?
two elements are mingled together without combining chemically.
two or more elements are fused together through a chemical reaction.
two identical atoms are joined together chemically.
two elements are combined such that they can no longer be identified by their individual properties.

Explanation:

A mixture is defined as a combination of substances where no chemical bonding occurs, so the components retain their individual properties and can be separated physically. The other options describe chemical reactions (forming compounds) or atomic bonding, which is not characteristic of mixtures.

Answer:

Two elements are mingled together without combining chemically.
