Be able to define each step of the scientific method. The atomic number determines the identity of an element and many of its chemical properties. Neutral atoms of an element contain an equal number of protons and electrons.

In simple terms an atom is a cloud of tiny electrons buzzing round a central much larger nucleus in a series of orbits called shells. Know the difference between a dependent and independent variable. Equal to the number of protons in the nucleus or electrons in the neutral state of an atom of an element.

Accordingly the number of protons which is always equal to the number of electrons in the neutral atom is also the atomic number.
