When atoms of different elements join and react together, they form chemical compounds through various types of bonds, such as ionic or covalent bonds. This process often involves the rearrangement of electrons, allowing the atoms to achieve a more stable electron configuration. The resulting compounds exhibit unique properties that differ significantly from the individual elements. Such reactions are fundamental to the formation of the diverse materials and substances found in nature.
Atoms of elements in group 18 (noble gases) do not easily combine with other elements to form compounds.
One of the best ways to describe John Dalton's observations of elements is that they are made of small particles. The atoms join in simple whole number ratios when the elements react.
Atoms of two different elements react with each other when they have a tendency to achieve a stable electron configuration, typically resembling that of the nearest noble gas. This often occurs through the transfer or sharing of electrons, leading to the formation of ionic or covalent bonds. The reactivity depends on factors such as electronegativity and atomic size, which influence how easily atoms can gain, lose, or share electrons.
There are very many elements which will do that.
If the elements are mixed, but do not react, this is a mixture, or possibly a solution.If the substances chemically react to form a new substance, then it is a chemical reaction, and the substance created (through chemical bonding) is a compound.The smallest unit of a compound is a molecule, which consists of two or more atoms in a specific arrangement.(Molecules can also be made of one element, and are called allotropes.)
because they are chemically joined together and it is difficult to separate them
They form a compound.
== == When metals react with other elements, the atoms of the metals give up their valence electrons.

Atoms of non-metals usually gain or share electrons when they react with other atoms.
When 2 or more elements react together, they can form a compound. A compound is a substance made of two or more different elements that are chemically bonded together. The elements combine to create a new substance with unique properties.
The building blocks of a compound are atoms. Atoms combine together to form molecules, which in turn make up compounds. The specific types of atoms and how they are bonded together determine the properties and characteristics of the compound.

They are all the same in that they have the same numbers of protons and electrons and therefore react in the same way. However, most elements can have atoms with different numbers of neutrons (isotopes), and therefore different masses.
