What are the five principles of the atomic theory

The atomic theory, a cornerstone of modern science, rests on five key principles: matter is composed of atoms, atoms of an element are identical, compounds form from atom combinations, chemical reactions rearrange atoms, and atoms are indivisible. Together, they unveil the universe’s intricate tapestry.

What is the 3 atomic theory

The three atomic theory, proposed by John Dalton in the early 19th century, revolutionized our understanding of matter. It posits that all matter is composed of indivisible atoms, which combine in fixed ratios to form compounds, laying the groundwork for modern chemistry.

What is the 4 atomic theory

The four atomic theory, proposed by ancient philosophers, posits that all matter is composed of four fundamental elements: earth, water, air, and fire. This early framework laid the groundwork for modern atomic science, shaping our understanding of the universe.
