Choose the ascending micro→macro order: 1) Atom 2) Matter 3) Molecule 4) Electron

Introduction / Context:We order physical entities from smallest constituent to bulk substance.

Given Data / Assumptions:Electron is subatomic; atoms combine to form molecules; large collections of molecules constitute matter.

Concept / Approach:Simple hierarchy: electron → atom → molecule → matter.

Step-by-Step Solution:

Verification / Alternative check:Any other order breaks composition logic.

Why Other Options Are Wrong:They misplace electron or put matter too early.

Common Pitfalls:Thinking molecules are smaller than atoms (they are groups of atoms).

Final Answer:4 1 3 2
