Noble gases are found as monatomic molecules

Noble gases are found as monatomic molecules is a TRUE statement.

Explanation:

Noble gases are monoatomic elements. That is they exist as a single atom in nature.

Noble gases are the only elements which are stable at room temperature and pressure.

Except helium which has 2 valence electrons all other elements have 8 valence electrons (electrons in the outer shell) This is the reason why the noble gases are non reactive that is they are inert in nature.

It is difficult to oxidize or reduce noble gases and hence they form very few compounds.

explanation:

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
