Is the atomic weight of an element is equal to the number of protons minus the number of neutrons?

No, the atomic weight of an element is not equal to the number of protons minus the number of neutrons. Atomic weight is the average weight of an element's isotopes taking into account their abundance, which includes the sum of the protons and neutrons in the nucleus.

How do you get the atomic number and weight?

The atomic number of an element is equal to the number of protons in its nucleus. The atomic weight is the average mass of an element's isotopes, taking into account their relative abundance. Both the atomic number and weight can be found on the periodic table for each element.
