Chemistry

Not quite remember

I easily remember

Dalton’s Atomic Model (1)

Matter is made up of particles called atoms

Dalton’s Atomic Model (2)

An atom is the smallest spherical body

Dalton’s Atomic Model (3)

An atom cannot be created

Dalton’s Atomic Model (4)

An atom cannot be destroyed nor divided further

Thomson’s Atomic Model (1)

Discovered negatively-charged particles called electrons

Thomson’s Atomic Model (2)

Atom is a positively-charged sphere with several electrons in it

Rutherford’s Atomic Model (1)

Nucleus is the centre of the atom

Rutherford’s Atomic Model (2)

Discovered positively-charged particles called protons in the nucleus

Rutherford’s Atomic Model (3)

Almost the whole of atomic mass is concentrated in the nucleus

Rutherford’s Atomic Model (4)

Electrons move outside the nucleus
