What is modern atomic theory?

Modern atomic theory is a scientific model that describes the nature of atoms, their structure, and behavior.

What are the main components of an atom?

An atom consists of protons, neutrons, and electrons. Protons and neutrons form the nucleus, while electrons orbit around it.

How has atomic theory evolved over time?

Atomic theory has evolved from early ideas by Democritus to Dalton's model, Thomson's discovery of electrons, Rutherford's nucleus, and Bohr's quantized orbits, leading to the modern quantum mechanical model.

What is the significance of quantum mechanics in atomic theory?

Quantum mechanics is crucial in atomic theory as it explains the behavior of particles at the atomic level, including electron configurations and chemical bonding.

Can you explain the concept of isotopes?

Isotopes are variants of a chemical element that have the same number of protons but different numbers of neutrons, resulting in different atomic masses.
