Don't forget about excited states. Francium is not used much because it has a lifetime too short to do meaningful experiments with it, but the 7s orbital comes into play often when dealing with cesium.Veronica_Oles said:
Orbitals are regions in an atom where there is a high probability of finding electrons. They are represented by different shapes and orientations, and each orbital can hold a maximum of two electrons.
The four types of orbitals are s, p, d, and f. S orbitals are spherical, p orbitals are dumbbell-shaped, d orbitals are cloverleaf-shaped, and f orbitals are more complex in shape.
Francium is a highly reactive, radioactive element with the symbol Fr and atomic number 87. It is used in studying the properties of the 7s orbital, as it has seven electrons in this orbital.
The 7s orbital is the outermost orbital in an atom and has the highest energy level. It can hold up to two electrons, and these electrons have the highest energy among all the electrons in an atom.
The arrangement of elements in the periodic table is based on the number of electrons in their outermost energy level, which is related to the type of orbital they have. For example, elements in the first column have one electron in their outermost s orbital, while elements in the second column have two electrons in their outermost s orbital.
