Why aren't there many more than 100 occurring elements?
Because scientists just simply add a proton to an element, and they get the next element. For example, of you had one sodium atom (all sodium atoms have an atomic number of 11), and added a proton to it, you would get magnesium atom (all magnesium atoms have an atomic number of 12). So if scientists did this with element 99, they get element 100.
What atomic number would an isotope of uranium have?
