The number next to any isotope represents the mass number
The most common plutonium isotope is plutonium 239.
254 is the mass number of the isotope Fm-254.
It represents the mass number of that particular isotope.
The symbol Po-210 represents the isotope of Polonium with a mass number of 210.
Thallium has two stable isotopes: Tl-203 (29.5%) and Tl-205 (70.5%). The percentages represent the relative abundance of each isotope in naturally occurring thallium.
it equals the atomic number of balls plus dick which is B^2*D^2
Let x represent the relative abundance of the isotope with mass 150.9196 amu and 1-x represent the relative abundance of the other isotope with mass 152.9209 amu. The average atomic mass formula is [(mass isotope 1)(abundance isotope 1) + (mass isotope 2)(abundance isotope 2)] = average atomic mass. Substituting the values given, you can set up a system of equations and solve for x to find the relative abundance of each isotope.
The corresponding atom is the isotope, potassium-39.
The number 218 in polonium-218 represents the total number of nucleons (protons and neutrons) in the nucleus of that specific isotope of polonium. It refers to the sum of protons and neutrons in the atomic nucleus of the polonium-218 atom.
The symbol for the radioactive isotope Carbon-14 is ^14C. The superscript 14 indicates the mass number of the isotope, which is the sum of protons and neutrons in the nucleus. The letter C represents the chemical element carbon.
