Which of these are compounds, and which are molecules? Explain. Answers: Salt (NaCl) contains two different elements, sodium and chloride, so it is a compound. Molecular hydrogen (H2) contains two atoms of the same element of hydrogen. Since H2 contains two or more elements, but the ...
Molecules Chemical compounds are made from atoms of elements that are bonded together. The smallest chemical compound is one molecule. These compounds can be organic or inorganic. Answer and Explanation: Learn more about this topic: Chemical Properties of Organic Compounds ...
when taken in combination, produced the basic building blocks of all things. Molecules, they called them, taken from the Latin “moles” (which means “mass” or “barrier”). But used in the context of
It is known that molecules or formula units are formed by the sharing of electrons (molecular bonds) or ionic charge attraction, respectively. Many compounds of chlorine are binary, where only chlorine as chloride bonds to one ion or atom....
