All elements and compounds are present in molecular state. They cannot be found as individual atoms. Atoms cannot exist in free state.

Most molecules are compounds but not all. Some molecules such as O2 and P4 are elements.


How are atoms related to molecules and compounds?

An atom is the smallest component of any element having all the chemical properties of that specific element. A molecule is the simplest complete structural unit of an element or compound that can exist in nature. A compound is a substance consisting of two or more different elements or molecules formed by the chemical union of two or more elements or molecules in definite proportion by weight.

Why all compounds are molecules but not all molecules are compound?

A few elements normally exist as molecules: hydrogen, nitrogen, oxygen, and the halogen gasses of group 7 on the periodic table. Two atoms of these gasses will combine to form a molecule (such as H2, O2, Cl2), but since they are the same type of atom, they are not compounds.


Are all compounds molecules?

YES!!!!!!!! All compounds are molecules HOWEVER not all molecules are compoundsTechnically, no. Ionic compounds form a crystal lattice rather than individual molecules. A compound is any combination of at least two different elements.


What is the main difference between a molecule and compound?

A molecule is formed when two or more atoms join together chemically. A compound is a molecule that contains at least two different elements. All compounds are molecules but not all molecules are compounds.


The relationship between elements atoms ions molecules and compounds on the structure of matter?

An atom is the smallest component of any element having all the chemical properties of that specific element. A molecule is the simplest complete structural unit of an element or compound that can exist in nature. Ions are atoms or molecules that have become electrically charged (positive or negative) by having lost or gained one or more electrons. A compound is a substance consisting of two or more different elements or molecules formed by the chemical union of two or more elements or molecules in definite proportion by weight.


Which elements will occur as diatomic molecules and cannot exist as individual atoms?

All elements can exist as individual atoms in excited states. However, at standard temperature and pressure, hydrogen, nitrogen, oxygen, fluorine, chlorine, bromine, and iodine exists as diatomic molecules.
