Physical Science 1

Big Bang Theory

Explains how the universe began, involving cosmic expansion and nucleosynthesis.

Atom

The fundamental building block of matter, consisting of protons, neutrons, and electrons.

States of Matter

Refers to the three main forms of matter - solid, liquid, and gas.

Atomic Theory

States that matter is composed of tiny, indivisible particles called atoms.

Evolution of Atom Models

Describes the historical development of atomic models from Atomism to the Nuclear Model.

Nucleosynthesis

The process of creating new elements through nuclear fusion, occurring in events like the Big Bang and stellar processes.

Isotopes

Variants of elements with the same number of protons but different numbers of neutrons, leading to different atomic masses.

Stellar Nucleosynthesis

The formation of elements within stars through processes like the Proton-Proton Chain and CNO Cycle.

Proton-Proton Chain Reaction

Fusion of hydrogen nuclei to form helium in stars.

CNO Cycle

Conversion of hydrogen to helium using carbon in stellar nucleosynthesis.
