The number of protons (also called the Atomic Number) of an element makes it what it is. All we need to do is find the element on the Periodic Table and read its Atomic Number: So for example, Fluorine has the symbol F and has 9 protons. That means this element in its neutral state has 9 electrons.
A type of atomic spectroscopy capable of qualitatively or quantitatively determining certain cations (particularly Na, K, Rb, Cs, Ca, Ba, Cu) by utilizing a low temperature flame capable of exciting a valence electron to an upper energy state which emits light at a wavelength unique to each cation as the electron returns to its ground state.
Aufbau Principle - electrons fill orbitals starting at the lowest available energy state before filling higher states (1s before 2s). Pauli Exclusion Principle. An orbital can hold 0, 1, or 2 electrons only, and if there are two electrons in the orbital, they must have opposite (paired) spins. When we draw electrons, we use up and down arrows.
