How Many Orbitals Does Hydrogen Have

"On the Number of Orbitals of Hydrogen"

Hydrogen is the first element. It is often studied by scholars in the study of atomic structure and the number of orbitals.

Hydrogen atoms have only one electron. According to quantum mechanics, their energy levels are different, and their orbitals are also different. For the orbit of hydrogen, the principal quantum number\ (n\) can be\ (1,2,3,\ cdots\).

When\ (n = 1\), there is only\ (1s\) orbital, which is where the ground state hydrogen electrons live. This\ (1s\) orbital is spherically symmetric and is the orbital of the lowest energy of a hydrogen atom.

As the value of\ (n\) increases, such as\ (n = 2\), there are\ (2s\) and\ (2p\) orbitals.\ (2s\) orbitals are also spherical, but their energy is higher than\ (1s\).\ (2p\) orbitals have three orbitals,\ (2p_x \) 、 \( 2p_y \) 、 \( 2p_z\), which are dumbbell-shaped, perpendicular to each other, and have degenerate energies.

If\ (n = 3\), there are\ (3s \) 、 \( 3p \) 、 \( 3d\) orbitals.\ (3s\) is spherical,\ (3p\) has three and is dumbbell-shaped, and\ (3d\) has five, which is more complex.

In summary, the number of orbitals of hydrogen atoms increases with the increase of the principal quantum number\ (n\). When\ (n = 1\), there are\ (1\) orbitals; when\ (n = 2\), there are\ (1 + 3 = 4\) orbitals; when\ (n = 3\), there are\ (1 + 3 + 5 = 9\) orbitals. According to this law, when the principal quantum number is\ (n\), the total number of orbitals is\ (n ^ 2\). Therefore, the number of orbitals of hydrogen atoms varies according to different energy levels, from one of the ground states to the higher energy level, the number of orbitals gradually increases, following the rules of quantum mechanics, and developing the wonders of atomic microstructure.
