Question
Which of the following statements is true regarding molecules and compounds?Multiple choice question.Molecules always consist of less than 24 atoms, and compounds always consist of 24 or more atoms.Molecules consist of just one element, and compounds are composed of different kinds of elements.Molecules and compounds are both made of atoms.
Solution
The correct statement regarding molecules and compounds is: "Molecules and compounds are both made of atoms."
Here's why:
-
"Molecules always consist of less than 24 atoms, and compounds always consist of 24 or more atoms." - This statement is false. The number of atoms in a molecule or compound can vary greatly and is not limited to a specific number.
-
"Molecules consist of just one element, and compounds are composed of different kinds of elements." - This statement is also false. Molecules can consist of one or more types of elements. Compounds, by definition, are made up of two or more different kinds of elements.
-
"Molecules and compounds are both made of atoms." - This statement is true. Both molecules and compounds are made up of atoms. A molecule is the smallest particle in a chemical element or compound that has the chemical properties of that element or compound. Compounds are made up of molecules that are made up of atoms.
