What describes a chemical compound?
A chemical compound is a chemical substance composed of many identical molecules (or molecular entities) composed of atoms from more than one element held together by chemical bonds. A molecule consisting of atoms of only one element is therefore not a compound.

Which statement correctly describes a compound is a pure substance?
Which statement correctly describes whether a compound is a pure substance? A compound is a pure substance because its molecule cannot be broken down into simpler particles by physical means.
What is a compound example?
An example of such is hydrogen gas H2 H 2 . Compounds are substances that are made of two or more different atoms present in a fixed ratio. An example is carbon dioxide CO2 C O 2 , it is a compound as it is made up of two different elements. The atoms in compounds are joined together through chemical bonds.
How do you classify a compound?
Chemical compounds may be classified according to several different criteria. One common method is based on the specific elements present. For example, oxides contain one or more oxygen atoms, hydrides contain one or more hydrogen atoms, and halides contain one or more halogen (Group 17) atoms.

What is compound made of?
chemical compound, any substance composed of identical molecules consisting of atoms of two or more chemical elements. All the matter in the universe is composed of the atoms of more than 100 different chemical elements, which are found both in pure form and combined in chemical compounds.
Which is not A compound quizlet?
All compounds are molecules but not all molecules are compounds. Molecular hydrogen (H2), molecular oxygen (O2) and molecular nitrogen (N2) are not compounds because each is composed of a single element. Water (H2O), carbon dioxide (CO2) and methane (CH4) are compounds because each is made from more than one element. .
