The px, py, and pz orbitals are part of the p orbital set in an atom. They have different shapes and orientations in space. The px orbital is shaped like a dumbbell along the x-axis, the py orbital is shaped along the y-axis, and the pz orbital is shaped along the z-axis. These orbitals have different energy levels and can hold a maximum of 6 electrons.
Rhythm
You count how many times it happens in each equal period of time. Once you havethat number, you can say that the frequency of the event is that many per hour,or that many per year, or that many per minute.If it's that many per second, then the frequency is that many 'Hertz'.
The string that has the highest frequency is the one that appears most frequently within a given set of strings.
In a theory, the mechanism or framework is used to explain how things happen. It consists of concepts, principles, and relationships that aim to provide a systematic explanation of a phenomenon or set of phenomena. Theories serve as a guide to understanding and predicting how events unfold based on underlying principles.
A set of p type orbitals can hold a maximum of 6 electrons, with each p orbital able to hold a maximum of 2 electrons. This is because there are three p orbitals (px, py, pz) available for electrons to occupy in a given energy level.

A subset, A, of a given a set S, consists of none or more elements that belong to S.

Molecular orbitals are formed by the overlap of atomic orbitals from different atoms in a covalent bond. These molecular orbitals have distinct shapes and energies compared to the atomic orbitals they are formed from. The number of molecular orbitals formed is equal to the number of atomic orbitals that combine.
If the set has n elements then it has 2n subsets.
There are three p orbitals in all levels 2 and above. these are the px, py and pz orbitals, the (suffix is the direction - px lies along the x axis). In the 5th level they will be 5px, 5py, 5pz
"Degenerate" in this sense means "indistinguishable" or more specifically "having the same energy." Properly speaking, the word shouldn't be used for a single orbital; it refers to the relationship between two or more orbitals. For example, in an isolated atom, the three p orbitals in a given shell are said to be degenerate, since they all have the same energy level.
The hybridization of SF5- is sp3d2. This is formed by mixing one s orbital, three p orbitals, and two d orbitals to form a set of six sp3d2 hybrid orbitals around the sulfur atom in SF5-.
The theory that all orbits of a given degenerate set must be singly occupied before pairing is known as Hund's Rule. It states that electrons will fill degenerate orbitals (orbitals of the same energy level) singly and with parallel spins before any orbital is doubly occupied. This minimizes electron-electron repulsion and stabilizes the atom. Hund's Rule is crucial in understanding the electron configuration of atoms in quantum chemistry.
"sp3d2" refers to the hybridization of atomic orbitals in a molecule where 1 s orbital, 3 p orbitals, and 2 d orbitals combine to form a set of 6 equivalent hybrid orbitals. This hybridization is commonly found in octahedral molecules where the central atom is surrounded by six electron pairs.
