How many degenerate orbitals can be found in each p subshell?

3

Explanation:

For p-subshell we have the value of angular quantum number as l = 1 & the degenerate orbitals are numbered from -l to +l.

This is in accordance with the Schrodinger's model that allows the electron to occupy a three dimensional space. It therefore requires three quantum numbers, to describe the orbitals in which electrons can be found. The three coordinates that come from Schrodinger's wave equations are the principal (n), angular (l), and magnetic (m) quantum numbers.

These quantum numbers decide the shape, size and orientation in space of the orbitals on an atom.

the answer is d

explanation:

dan realized that his goal of going to an ivy league school if only he works hard which means basically this   to become completely aware of (something) as a fact; understand without a doubt to make (something desired or anticipated) occur to give real, definite or physical form to a plan, dream, or goal to earn (money or a profit) from a deal
