FAQs on Atoms and Molecules

Question 1

1. What is an atom?

Accepted Answer

Ans. An atom is the smallest unit of matter that retains the properties of an element. It consists of a nucleus containing protons and neutrons, surrounded by electrons.

Question 2

2. How do atoms combine to form molecules?

Accepted Answer

Ans. Atoms combine to form molecules through chemical bonding. This involves sharing, gaining, or losing electrons to achieve a stable electron configuration.

Question 3

3. What is the difference between an atom and a molecule?

Accepted Answer

Ans. An atom is a single particle, while a molecule consists of two or more atoms chemically bonded together. Molecules have different properties than individual atoms.

Question 4

4. Can atoms of different elements form a molecule?

Accepted Answer

Ans. Yes, atoms of different elements can combine to form molecules. These molecules are called compounds and have unique chemical properties based on the elements involved.

Question 5

5. How do scientists study atoms and molecules?

Accepted Answer

Ans. Scientists study atoms and molecules using techniques such as spectroscopy, microscopy, and crystallography. These methods help determine the structure and behavior of atoms and molecules.
