Question

its time for the unit exam. this is your opportunity to show how much you hav if you dont feel ready, you may want to stop and clarify anything you do not und over any notes you have taken and review the key terms. good luck! note: to answer some of the questions, it may help to reference a periodic table when is a compound considered binary? when it has at least one double bond when it has two different elements bonded together when it has two of the same elements bonded together when it has two atoms

Explanation:

A binary compound is defined as a compound that consists of two different elements. For example, NaCl (sodium chloride) has two different elements (sodium and chlorine). A double - bond is related to the type of chemical bond (covalent bond type) and not the definition of a binary compound. If two of the same elements are bonded together, it is a diatomic molecule (e.g., \(O_2\)) which is not a compound. Having two atoms is too vague as they could be of the same element.

Answer:

when it has two different elements bonded together
