An s orbital with zero net orbital angular momentum is spherical. A p orbital with one fundamental unit of angular momentum, {Planck constant}, is shaped somewhat like a dumbbell ({Planck constant} is Planck’s constant, h, divided by 2p). The shapes of the other orbitals are more complicated.
s轨道角动量为0，轨域为球形。p轨道有1个角动量基本单位，轨域为哑铃状(为普朗克常数除以2π)。其余轨道的轨域形状更加复杂。

An orbital can be considered a three-dimensional region in which there is a 95% probability of finding an electron. Atomic orbitals are designated by a combination of numerals and letters (e.g., 1s, 2p, 3d, 4f). The numerals are the principal quantum number and are related to the atomic energy level and distance from the nucleus; the letters indicate the orbital’s angular momentum and hence its shape.
轨道常被视为电子出现的机率为95%的三维区。原子轨道是用代表轨道电子特性的数字和字母的组合来标记(例如1s、2p、3d、4f)，其中的数字是主量子数，它标出能级和距原子核的距离，而字母标明轨道的角动量和依角动量所决定的形状。
