Isotopes have different masses, so the superscript preceding the symbol will be different. An example could be carbon with Atomic Mass 12 and carbon with atomic mass 14. 12C and 14C with the 12 and 14 being superscripts, identifies the different isotopes.
The atomic number is usually written to the lower left of the atomic symbol. The atomic mass is usually written to the upper right of the atomic symbol. So, carbon-14 would look like this: 6C14
You don't; you look it up in a table of nuclides. It's very difficult (as in, essentially impossible) to predict things like this.
Since turquoise is a mineral rather than an element it does not have a symbol as a chemical element. If you wish more information about it you might look at its page on wikipedia.
79 protons go to the peridic table of elements, look for your element, look at the bottom of your element and there should be a number. then round that number to the nearest whole number and there you have it, the most common isotope of yourelement
Isotopes of an element have the same number of protons but different numbers of neutrons. So, for boron, look for illustrations that show different numbers of neutrons in the nucleus while maintaining the same number of protons.
Look at the Periodic Table.
That is the chemical symbol of an element, such a H for hydrogen, Hg for mercury, etc.
there is no symbol of the gurdwara
a#
The 'at' symbol is @ .
The declarative symbol is a period. .
