Question

question 4 (1 point) the magnetic quantum number of an orbital defines: the size of the atom the energy level of the outermost electron the shape of the orbital the spatial orientation of the orbital the spin of the electrons in each orbital

Explanation:

The magnetic quantum number ($m_l$) of an orbital defines the spatial orientation of the orbital. The spin of electrons is defined by the spin - quantum number ($m_s$), the shape of the orbital by the angular - momentum quantum number ($l$), and the energy level of the outermost electron is related to the principal quantum number ($n$) and other factors. The size of the atom is related to multiple factors including the principal quantum number of the outermost electrons.

Answer:

The spatial orientation of the orbital
