James Chadwick

Founder of modern chemistry

Antoine Lavoiser

Model that states: matter is composed of small, indivisible particles called atom

Dalton model

Model that states: Atoms are negatively charged electrons within a positive soup

Tomson model/ Plum pudding model

Model that states: Atoms have a small, dense, positively charged nucleus with electrons orbiting around it

Rutherford model / Gold fold experiment

Model that states: Idea of quantized electron orbits, where electrons can occupy specific energy levels around the nucleus

Bohr model

4

Higher the valence electron, _

more inductive the material
