Which is a correct comparison between the modern quantum model and John Dalton’s model of the atom?

No comparison => John Dalton did NOT postulate an atomic structure.

Explanation:

Dalton's postulates are based upon generalizations of observable phenomena. Micro structure was not proposed.  The atomic structure that's accepted in the scientific community evolved from conclusions of ...

Thompson's raisen pudding model => electrons suspended in a positive matrix

Rutherford's shell model => dense positive nucleus surrounded by an electron cloud. (No fine structure postulated)

Bohr Concentric Ring Model => electrons orbiting a positive nucleus in discrete  energy levels much like planets orbiting the sun.

Schrodinger - Dirac Quantum Models => electrons occupying specific orbital energy levels as based upon statistical wave mechanics.

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer

because it is
