The modern-day quantum model of the atom is better than john dalton’s model because it is easier to understand. is a more recent theory. can be represented in two dimensions. answers many questions about atoms.

The answer is: answers many questions about atoms.

Quantum model, for example, describe position of electrons with quantum numbers.

For example, electron in 2pz orbital.

The principal quantum number is one of four quantum numbers which are assigned to each electron in an atom to describe that electron's state, n=1,2,3... n=2 - the second energy level.

The azimuthal quantum number is a quantum number for an atomic orbital that determines its orbital angular momentum and describes the shape of the orbital. l = 0,1...n-1, when l = 1, that is p subshell.

The magnetic quantum number, ml, show orbital in which the electron is located, ml = -l...+l, ml = 0  is pz orbital.

The spin quantum number, ms, is the spin of the electron; ms = +1/2 or -1/2.

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
