Why are atoms and molecules different?

Answer 1

Owen Ambrose

Atoms and molecules are very different to each other. This can be explained as follows:-

Atoms are the basic unit of every substance and make everything present around us.
Molecules on the other hand are formed due to the combination of atoms. Therefore, we can define molecules as a group of atoms which are formed due to chemical bonds.
So, in short we can say that atoms are the building blocks of everything present around us but when those atoms combine with each other due to chemical bonds they become molecule .
Lastly, please emphasise on the fact that an atom is a single unit but a molecule is a group of atoms which are held together by a chemical bond .

Atoms are different because they have different numbers of protons, neutrons, and electrons, which determine their chemical properties. Molecules, on the other hand, are different because they consist of different combinations of atoms, resulting in unique chemical structures and properties.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
