False.
Dalton's atomic theory assumed that atoms are the smallest and indivisible units.
Dalton worked during the early years of 1800s. The electron was discovered in 1897.

What is an atom? What are atoms made of?
Atoms are the basic building blocks of ordinary matter. Atoms can join together to form molecules, which in turn form most of the objects around you.
Atoms are composed of particles called protons, electrons and neutrons. Protons carry a positive electrical charge, electrons carry a negative electrical charge and neutrons carry no electrical charge at all. The protons and neutrons cluster together in the central part of the atom, called the nucleus, and the electrons 'orbit' the nucleus. A particular atom will have the same number of protons and electrons and most atoms have at least as many neutrons as protons.
Protons and neutrons are both composed of other particles called quarks and gluons. Protons contain two 'up' quarks and one 'down' quark while neutrons contain one 'up' quark and two 'down' quarks. The gluons are responsible for binding the quarks to one another.

the answer is 100% false!!!
Protons, neutron and electron wheren't found until my later. Dalton's atom looked like a solid sphere. Much like a cue ball.

Democritus first suggested the existence of the atom but it took almost two millennia before the atom was placed on a solid foothold as a fundamental chemical object by John Dalton (1766-1844). Although two centuries old, Dalton's atomic theory remains valid in modern chemical thought.

False - Dalton was not aware of the existence of subatomic particles.

true by the way...electrons are outside of the nucleus which is orbiting around the atom.
