screening and evaluation
If there are two or more elements or compounds physically combined, then it can no longer be an element.
Combined elements refer to two or more substances or components that have been physically or chemically mixed together to create a new compound or mixture. These combined elements can exhibit properties different from those of the individual elements.
compound
When two or more elements are combined chemically, they form a compound. This involves the elements bonding together through chemical reactions to create a new substance with its own unique properties.
The elements are: two hydrogen atoms and one oxygen atom. Combined they form water (H2O).

Compound
When two of the same elements are bonded together, it is called a diatomic molecule.
two or more elements and/or compounds that are physically combined.
they are two or more elements that are chemically combined
Compounds are composed of two or more elements that are chemically combined in definite proportions. The elements in a compound are held together by chemical bonds, which result in a unique set of properties different from the elements that make up the compound.
