Element Molecules Definition
An element is a pure substance consisting only of atoms that all have the same number of protons in their atomic nuclei. This means all atoms within a single element are identical in terms of their fundamental properties.
Molecular Composition of Elements
When atoms of an element combine to form molecules, these molecules are invariably composed of only the same type of atoms.
- For example, a molecule of oxygen gas (O2) consists of two oxygen atoms bonded together.
- Similarly, a molecule of nitrogen gas (N2) consists of two nitrogen atoms.
Distinction from Compounds
Molecules formed from different type of atoms are characteristic of compounds, not elements. For instance, a water molecule (H2O) is made of hydrogen atoms and oxygen atoms.
Conclusion
Therefore, the molecules of an element are defined by being constituted by only one kind of atom.
