Because all the atoms of these elements in Family 18 have filled outermost energy levels.
Elements tend not to undergo chemical reactions that decrease stability. Chemical reactions typically result in products that are more stable than the reactants involved. Elements tend to form compounds to achieve a more stable electron configuration.
Chemical reactions that involve the rearrangement of atoms in reactants to form new compounds are evidence that elements can combine to form new compounds. Additionally, the existence of a wide variety of compounds with unique properties and compositions further supports this concept. The ability to predict the outcomes of chemical reactions using the principles of stoichiometry and chemical bonding also demonstrates the combination of elements to form compounds.
No and element cannot be broken down or changed into another substance through a chemical change. The number of protons in the nucleus of an atom determines the identity of the substance. But, a chemical change involves only the atoms electrons. -SmartyPants94
Yes, that is true. Atoms of different elements can combine to form compounds through chemical reactions. This is the basis of modern atomic theory, which explains how elements interact and combine to form new substances.
Almost all elements are capable of some kind of chemical bond; they could be called reactive elements since they undergo chemical reactions. Those which do not undergo chemical reactions are said to be inert.
Family 18
Chemical reactions are what causes elements to chemically combine to form compounds.

Elements combine to form compounds through chemical reactions. These compounds have different properties than their individual elements, resulting in a wide range of substances found in nature and synthesized in laboratories.
some but not all......many reactions are reversible and many r irreversible....depends on chemistry of reactions, physical change or chemical change...
Yes, elements in a compound can be separated through chemical reactions such as electrolysis or decomposition. These reactions break the bonds between the elements, allowing them to be isolated in their pure form.
they are 2 completely different substances usually- If they combine they make a compound or a molecule. this is 2 substances together. Example- H2O=Oxygen+2 Hydrogin atoms(water)

When an element "decays", it forms a different element. This is the definition of "decay" when referring to radioactive elements.

Elements are the simplest form of matter and are made up of atoms. Atoms are the basic building blocks of elements and combine to form molecules. Molecules are made up of two or more atoms bonded together. In the context of chemical composition, elements combine to form molecules through chemical reactions, creating different substances with unique properties.
No, not only phosphorus can form stable compounds. Many elements can combine to form stable compounds depending on their chemical properties and bonding capabilities. These compounds can be created through various chemical reactions involving different elements.
