Yes, it is true.
false
By subtracting the mass number and the atomic number, the number of neutrons can be calculated.
The average number of neutrons that a specific element has is equivilent to the element's atomic mass minus the that elements atomic number. For example Helium has 2 neutrons because its atomic mass (4) minus the atomic number (2) is 2.
No, the number of protons is equal to the atomic number, which is also the same as the number of electrons in a neutral atom. The atomic mass, on the other hand, is the sum of the protons and neutrons in an atom's nucleus.
Roughly, the number of neutrons. Note that the atomic mass is only approximately equal to the number of protons plus the number of neutrons - there is a relatively small discrepancy, due to the binding energy.

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.
It is not correct.
The average number of neutrons that a specific element has is equivilent to the element's atomic mass minus the that elements atomic number. For example Helium has 2 neutrons because its atomic mass (4) minus the atomic number (2) is 2.

Atomic mass minus the atomic number.
The number of neutrons is equal to the atomic mass of an isotope minus the atomic number (or the protons number) of the element. The atomic number of mendelevium is 101 and Md has isotopes with atomic masses between 245 and 260.

The atomic number is the amount of protons which will equal the amount of electrons. The average atomic mass minus the number of protons will equal the amount of neutrons.
Mass number minus atomic number = number of neutrons
Typically to find the number of neutrons, you first round the atomic mass to the nearest whole number. After that to you subtract the number of protons (which is the same as the atomic number) from the newly rounded atomic mass and the resulting number is the number of neutrons. lets use Carbon for example: Atomic mass: 12.01 Atomic mass rounded: 12.00 Number of Protons (same as atomic number): 6 (Rounded atomic mass - number of protons)=6 So Carbon has 6 neutrons. Hope that is easy enough to understand.
