A diatomic molecule
A dinuclear molecule
A binary compound.
Yes, most molecular compounds do not contain metals. (The term "nonmetal" properly applies only to elements, not compounds.)
Elements and compounds
binary compounds
The term that describes a type of chemistry crossword that focuses on elements and compounds with an electrically neutral charge is "stoichiometry."
The general term is "products", intuitively enough.
The binary compound among the options given is hydrogen sulfide, which consists of only two elements: hydrogen and sulfur. The other compounds, such as hydrogen sulfate, ammonium sulfide, and ammonium sulfate, contain more than two elements.
Electron configuration is a term applied to chemical elements not to compounds.
It is called a constant term. It is number only and contains no variables
term
The term is formula : the combination of symbols for elements and ions that make up a compound.
The "occurrence" of an element refers to its relative abundance in nature. The term can also refer to the form in which the element appears (many elements are not found in their pure form--only in compounds with other elements) or the geographical distribution of the deposits of the element.
