What determines the properties of an atom?

The number of electrons, in turn, determines the chemical properties of the atom. Protons contribute to the mass of an atom and provide the positive charge to the nucleus. The number of protons also determines the identity of the element. An element’s chemical properties depend on its valence electrons.

How do you determine the atomic structure of an element?

The atomic number tells you the number of protons, and if the atom is neutral, the number of electrons, and that electrons are located in the electron cloud surrounding the nucleus. If you know the atomic number of an element, you can determine the number of protons and electrons.
