3\. Below the symbol is the atomic mass. While this number is a weighted average of the masses of all isotopes of the element, if you round the number to the nearest whole number you will find the mass number of the most common isotope. For carbon the mass number (M) is 12. This ...

and come back to find that neither atom has decayed, then you can’t say too much about how long it’s been.Probablyless than an hour, but there’s a good chance it’s been more. However, if you have trillions of trillions...
Argon was difficult to discover and was suspected, but not proven, to exist by Henry Cavendish in 1785. It was another 100 years, in 1894, when it was first isolated and truly identified by British scientists, Lord Rayleigh and William Ramsay....
