There are no elements that are composed of molecules because elements are what can be found on the Periodic Table of elements and they are composed of atoms.
When many of these atoms are mixed together they can become molecular compounds because they share their valence electrons and create a bond.
Example:
Hydrogen (H) is an element, Oxygen (O) is also an element and together they can become
H20 which is a molecular compond more commonly known as a molecule.
helium is the answer.
Oxygen
O2
Yes, an element is composed of millions of identical atoms.
Compounds are composed from elements.
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.
Sodium is an element because it is composed only of sodium atoms, all of which have 11 protons in their nuclei.
An element is composed of atoms all with the same proton number(they are the same type). The only way the atoms in an element can vary is in the number of neutrons they have.
Yes, an element is composed of millions of identical atoms.
It is composed of one type of atoms: Zinc atoms. That is, by definition, an element.
Such a substance is always an element.
No an element is composed of 1 type of atom but a compound is composed of 1 or more atoms
No. Atoms are the building blocks of matter. Each element is composed of the same kind of atoms, according to their number of protons (atomic number). Molecules are composed of two or more atoms (they may be the same element or different elements), and compounds are composed of two or more kinds of atoms.
Most matter doesn't exist as individual atoms. Inert or "noble" gasses like helium and argon excepted, most matter exists in molecules that are composed of two or more atoms. Even pure oxygen isn't individual atoms; oxygen is the O2 molecule composed of TWO oxygen atoms. Except within the cores of stars, hydrogen, the most common element, normally exists as the H2 hydrogen molecule. So in general, matter is composed of molecules, which are composed of atoms.
Gold is an element. As such, it is composed of atoms of gold, which in turn are composed of protons, neutrons, and electrons.
Sodium is an element, therefore it is composed solely of sodium atoms.
A single type of atoms.
Neutrons.
it is a diatomic molecule
Diotomic Molecule.
