Atomic mass and atomic weight?

From the New World Encyclopedia, "Technically, atomic mass is equal to the total mass of protons, neutrons, and electrons in the atom (when the atom is motionless), plus the mass contained in the binding energy of the atom's nucleus."Mass number is the number of protons plus neutrons in an atom's nucleus. Mass number varies with individual isotopes due to the fact that atoms of the same element can have different numbers of neutrons.


Comparison between isotopes and isobars?

Isotopes and isobars are very different. Isotopes are different atoms of the same element that have varying atomic masses (such as U-237 and U-235; i.e. they differ only in the number of neutrons contained within the nucleus), while isobars are a computed line through a variable region that all have the same value (think about the lines on a meteorological map). The specific line around a low pressure system where the pressure at every point on the line is the same atmospheric pressure is an isobar. Isobars are nuclei of different elements having the same mass number but different atomic number.


Is a radioactive isotope good or bad?

It depends what you want to use it for. They are extremely dangerous and can kill you if exposed to the wrong kind, but they are also how much of the world's electricity is produced. Radioactive isotopes are also commonly used in medicine for a number of beneficial purposes. Radioactive isotopes are also what nuclear bombs use. Like most things in the world, they can be used for great good, and terrible harm... it just depends on what you do with it.
