They are isotopes.
They are isotopes. They are the same element with a different amount of nuetrons, which can be determined depending upon the Atomic Mass and the atomic number, which results in the changed atomic mass.
they are made up of the same element.

They are isotopes (same number of protons, differing numbers of neutrons) They should therefore have the same chemical properties (same atomic number = same number of electrons), but have slightly different physical properties ( one will naturally be heavier etc).
No. Atomic number is always a whole number. This would be the atomic mass.
You would subtract the atomic number from the mass number.
The atomic number of Argon is 18. So 30 of them the Atomic Number would be 540.
Atomic number is about protons. It symbolises the protons an atom has.
The top left number is the atomic number
The first four: 1. Be 2. C 3. O 4. Ne How I found this: Since Helium (He) has an atomic number of 2, add two to the atomic number of Be. Since the atomic number of Be is 4, and the atomic number of Helium is 2, you would add four plus two, which equals six. Carbon has an atomic number of six, so therefore it would be your next answer. The formula is the atomic number of Helium plus the atomic number of element you are provided with equals the atomic number of your answer. In simpler terms: atomic number of He+atomic number= atomic number of answer
Atomic number 82 is Lead (Pb).
Uranium is a non metal element. Atomic number of it is 92.
