yes
Plutonium is a not stable, radioactive element. The IUPAC table Atomic weights of the elements, 2009 don't mention an officially atomic weight for plutonium. But you can find tables with atomic masses of the all 20 known plutonium isotopes (Audi, Wapstra, Thibault, 2003).The atomic mass of the most important isotope (239Pu) is 239,052156.
Elements that have their atomic weights in parentheses are unstable and radioactive, some of these will decay in less than a second. The atomic mass in the parentheses is the most stable isotope of the element.
Of elements that have no stable isotopes, technetium has the lowest atomic number, which is 43.
When the number of neutrons changes, the atomic mass will change.
A bar graph would be best to compare the atomic weights of different elements, as it allows for easy visual comparison of values. Each element could be represented by a separate bar, with the height of the bar corresponding to the atomic weight of the element.
Yes, and they are called isotopes.
If an element is radioactive, it refers to the stability of their atomic nucleus. If that atomic nucleus is not stable, it is considered radioactive.
A radioactive element is characterized by having unstable atomic nuclei that decay and emit radiation in the form of alpha particles, beta particles, or gamma rays. This decay process results in the transformation of the element into a different element or isotope.
When a radioactive element decays, it produces radiation in the form of alpha particles, beta particles, or gamma rays. This decay process can transform the element into a different element or a different isotope of the same element.

No they are all different and even some atoms of the same element have different weights
Atoms with the same atomic number are all atoms of the same element. However, if the atoms have different molecular weights, they are isotopes of the same element.
The heaviest element that is highly radioactive is Ununoctium, which has an atomic number of 118.
