We NOW (currently) know that electrons move slowly on orbits around the nucleus.
True

What do we call our current model of the atom?
Quantum Model

What is the location and charge of electrons within an atom?
Electrons are in the nucleus and have a negative charge
Electrons are outside of the nucleus and have a negative charge
Electrons are in the nucleus and have a positive charge
Electrons are outside of the nucleus and have a positive charge
Which is a true statement?
Electrons have a neutral charge unless they are valence electrons
The nucleus is found in the center of an atom and contains protons and neutrons
The nucleus is found in the center of the atom and contains protons and electrons
