A compound A compound is "a substance formed when two or more chemical elements are chemically bonded together." Atoms and molecules This is a quick revision of what learners have just covered about atoms and molecules and being able to differentiate between the two. Sometimes only the elementary particles are really considered particles (photons electron etc.) Mixtures are impure substances that occur when pure substances (e.g. Examples include water (H 2 O) and table salt (NaCl). How Do Atoms Join Together To Make Different Substances? When two atoms share electrons between them they are locked together (bonded) by that sharing. Based on different relationships between elements, there are different types of bonds. A chemical bond is a force that holds two atoms together in a molecule.
Atoms join together to form elements elements join together to form compounds. , other times, any basic building block of a larger object can be a particle (molecules or atoms such as The name for two or more elements that are bonded to each other chemically is a compound. a group of atoms that are held together by covalent bonds. Most elements on Earth bond with other elements to form chemical compounds such as sodium (Na) and Chloride (Cl) which combine to form table salt (NaCl). Chemical reactions happen when chemical bonds are broken and formed. A compound is a type of molecule that includes two or more A pure substance made of only one kind of atom. A chemical substance is composed of one type of atom or molecule. A COMPOUND is made of two or more different atoms bonded together e.g. How do atoms combine to make different substances? A Chemical Bond is a mutual electrical attraction between the nuclei and valence electrons of different atoms that binds the atoms together.Energy is the energy required to break a chemical bond and form neutral isolated atoms.Likewise, a Shared Pair is a pair of electrons that is shared between two atoms.
