What does the principal quantum number determine? check all that apply. check all that apply. the possible number of electorns on particular orbital the energy of the electron on the outer shell the shape of the orbital the overall size of an orbital the orientation of the orbital the overall size of an atom the energy of an orbital

ii) the energy of the electron on the outer shell

iv) the overall size of an orbital

Explanation:

There are four quantum numbers to define the position and energy level of an electron in an atom

a) Principal : The principal quantum number (n) is to know the energy of an electron in an atom and its possible distance from the nucleus.

b) Azimuthal: It refers to the shape of the subshell or orbital of the electron and thus the angular distribution.

c) Magnetic: It refers to the number of orbits and their orientation in the subshell.

d) spin: It refers to the spin of the electron.

coral.

explanation:

coral. many marine organisms that produce calcium carbonate shells or skeletons are negatively impacted by increasing co2 levels and decreasing ph in seawater.
