It is impossible to provide an exact number of symbols that exist in the entire world since symbols are constantly being created and evolve across various cultures and languages. Symbols can range from letters and numbers to emojis, gestures, and cultural symbols, making it difficult to quantify the total number.
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.
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.
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.
A bunch of them can have 74 neutrons, this is because there are isotopes in the world.
A recent press release by Blizzard Entertainment reveals that a total number of 12 million active accounts exist in World of Warcraft.

Britnee and Nat do exist. There are a large number of people with these names in the United States, so they do exist in the world.
There are a bit more than 100 elements however there are far, far more than 100 millions compounds, each day more compounds are produced, there are a lot of compounds with unknown structure, not having official names. So the ratio is much bigger than 1 to a million

It is impossible to provide an exact number of microscopes that exist in the world due to the vast number of research institutions, universities, hospitals, and industries that use microscopes. The number of microscopes is constantly changing as new ones are produced and older ones are retired.
Yes, I exist in this world.
