Atomic structure

Slide 6 - Slide

Slide 7 - Slide

highest energy level / outermost electron shell

Slide 8 - Slide

atomic number = number of protons
number of protons = number of electrons
electron charge = - 1
proton charge = +1
electron + proton charges = overall charge of atom
electrostatic forces = keep electrons in place

Remember!
