For the 3pz atomic orbital, the azimuthal quantum number l=

+1

Explanation:

Solving the Schrödinger wave equation for particular atoms yields wave functions. A wave function is also known as an orbital. An atomic orbital is defined as a region in space where there is a high probability of finding an electron.

Each electron in an atom is described by four sets of quantum numbers, viz;

Principal quantum number

Azimuthal quantum number

Magnetic quantum number

Spin quantum number

Our emphasis here is on the azimuthal quantum number. The azimuthal quantum number specifies the shape of an orbital with a particular principal quantum number. The azimuthal quantum number for a 3p orbital is +1. The 3p level is triply degenerate and has the 3px,3py and 3pz orbitals all having an azimuthal quantum number of +1 but different magnetic quantum numbers.

space exploration has led to the development and technological improvement of many everyday items. (if this answer is wrong i will find the right answer) : )
