Because of their high reactivity atoms tend to react and lose their free state.
The reactivity depends on the no. of valence electrons. For eg Na has only one electron and thus loses it easily to have configuration of Argon
Every atom wants to achieve nearest noble gas configuration by reacting and be stable.

What other answers have hinted at but neglected to say is that atoms, which are composed of electrons, protons, and neutrons (for lack of a better description) always seek to be in the lowest energy configuration according to the number and arrangement of electrons in the closest noble gas.
The vast majority of atoms do not exist in a free state, as free atoms, because they become more stable when they share electrons with other atoms. A few do exist as free atoms: the noble gases, of course, as well as gold, and occasionally copper, silver, and platinum. When these are found in a free state, they are typically referred to as 'native copper', etc., and the fact that they can be found in a free state is a reflection of the ability of their electrons to achieve a fairly stable 'noble' configuration without sharing electrons with other atoms.

They do. But when their in that state their extremly unstable. Thats why most atoms are jam packed together. An unstable atom can hold the force of an atomic bomb if put under pressure. Thats why their not suppose to exist in free states. Their considered dangerous.

Atom is the smallest particle of matter. Everything is made up of matter. Even we the human beings are made up of matter. Atoms are made up of three main components namely - electrons, protons and neutrons. Electrons are possitve, Protons are negative and Neutrons are neutral. Molecules are made up of atoms which can stay in free state. For eg. Hydrogen molecule "H" can remain in a free state but "H" atom cannot. As atoms are nothing without combining to form a molecule and molecules are nothing without combining to form a specific substance. Thus, an atom can never exist in a free state

Atoms have electrons in their outer most shell known as valence electrons.The max no. of electrons this shell can accomodate is 8.If the atom has 8 electrons in its valence shell,it exists in its free state as it has no space for other electrons.But if it doesnt,it tends to either share or transfer/accept electrons to obtain an octet configuration(8 electrons)
This is why most of the atoms combine to form molecules of elements or compounds

Some do. Helium and the other Noble gases.
