A molecule is a combination of atoms that cannot be broken apart while still retaining the same properties as the larger substance that it is a part of.

What are elements composed of?

An element is a material that consists of a single type of atom. Each atom type contains the same number of protons. Chemical bonds link elements together to form more complex molecules called compounds. A compound consists of two or more types of elements held together by covalent or ionic bonds.

Do all elements consist of?

Are all elements ions?

All elemental atoms contain the same number of protons and electrons thus giving them a neutral charge. An ion is any element that contains a different number of protons and electrons resulting in either a positively or negatively charged atom. … Refer to an element with either a positive or negative charge as an ion.

What’s a molecular element?

What are Molecular Elements? Molecular elements are the chemical species that has at least two atoms of the same chemical element bonded to each other via chemical bonding.
