Subject: Chemistry Chapter: Atoms and Molecules
Topic: Atoms to Elements
You can call an element as the fundamental substance which consists of a single type of atom. Furthermore, elements comprise of smaller particles and can either be synthetic or man-made. The arrangement of elements in the periodic table is planned on the basis of the number of protons counted in increasing order.Also, when atoms are differently arranged in an element holding the number of protons, one would get different versions of that element. Example: both diamond and graphite are elements of carbon; however, they look quite different from one another.
Molecule
A molecule can be termed as the smallest unit associated with a chemical compound. It delivers the same chemical properties of that particular compound. Since molecules are built out of atoms which are jointly held via chemical bonds, there are chances of significant variance in terms of size and complexity.
For example, oxygen holds a molecular formula O2. Do we consider it as a molecule or compound? Whenever two or more atoms of the same element merge together, we tag them as molecules. Hence, O2 stays as an oxygen molecule.
