Final answer:

The periodic table organizes elements based on properties for prediction and analysis. It helps in identifying elements and understanding chemical behavior.


Explanation:

The periodic table is a vital tool in chemistry used to organize elements based on their properties such as atomic number, electron configuration, and chemical behavior. It helps scientists predict the behavior of elements and understand their relationships.

Some common uses of the periodic table include identifying unknown elements, determining their properties, understanding trends in chemical reactivity, and predicting the likelihood of element reactions and compounds formation.

2n² denotes the total number of orbitals in a shell of an atom with principal quantum number n. For example, if n = 2, then 2n² = 2 x 2² = 8, indicating there are 8 orbitals in the second shell.
