atoms
All elements are composed of atoms.
Yes, they are.
Einsteinium is composed from neutrons, protons an electrons - as all other elements.
Elements are composed of atoms.
At sufficiently high temperatures and low pressures, all elements are composed of atoms. At standard temperature and pressure, some elements are composed of molecules, usually diatomic molecules, as with nitrogen, hydrogen, oxygen, and all the halogens.
No. Elements are composed of atoms that have the same number of protons (atomic number) in their atomic nuclei. Compounds are composed of two or more elements that are chemically combined.

Atoms
Elements are the primary substances that make up all matter, and they cannot be broken down into simpler substances. Molecules are combinations of two or more atoms bonded together, which can also be components of matter. Both elements and molecules play a crucial role in the composition of all things in the physical world.
All matter, such as solids, liquids and gases, is composed of atoms. Any material that is composed of only one type of atom is called a chemical element.
Hair is composed mostly of a protein called keratin. Like all proteins, keratin is composed mainly of the elements carbon, hydrogen, oxygen, and nitrogen.
Dextrose, like all carbohydrates, is a compound composed of only the elements carbon, hydrogen, and oxygen.
