Timeline

432 BCE- Empedocles Empedocles was responsible for separating air as a separate substance. In his beliefs air, fire, water, earth mingle and separate under the compulsion of love and strife. 440 BCE- Democritus Democritus’s theory was the first theory to be contributed to the atomic theory. He proposed that the entire world was made up

Mr. Lee says: Atomic radius increases as you go DOWN a group because you are adding more energy levels (orbitals) of electrons... 1s, 2s, 3s, 4s, etc. Atomic radius decreases as you go from LEFT...

The study of atomic spectra is considered the key that solved the puzzle of the atomic structure, That was the work of the Danish scientist Niels Bohr upon which he was rewarded the Nobel Prize in 1922.

This document is about the structure of atom. These are my personal notes, i Really hope they help you. they helped me in 10 th and 12th to get a better

My chemistry students had a blast designing their own atomic theory timeline projects in the form of a foldable! This activity would also work well for a physical science project!

Scientists experimented and observed the elements and their behaviour which helped them figure out the existence of atoms and frame the atomic theory.

Do you know what are the five postulates of Dalton’s atomic theory? Here is a brief description of it. Read the whole post for more information. #atomic #matter #science #math #element
