In a way that relates to atoms or atomic structure.
The scientists studied the material atomically to understand its properties better.
Atomically → It is formed from "atom" (from Greek "atomos", meaning indivisible) and the suffix "-ically" (meaning in a manner relating to). The word "atomically" refers to something that relates to or is in the manner of atoms, often in the context of atomic structure or behavior.
Think of 'indivisible' ('atomos') to remember that 'atomically' means relating to the smallest units of matter.
