The main difference between isotopes of the same element is the number of neutrons in the nucleus. Isotopes have the same number of protons and electrons but different numbers of neutrons, which affects their atomic mass.
An isotope of an element is same as the element in that it has the same number of protons. An isotope of an element is different from the element in that it has a different number of neutrons.
Isotopes of the same element have the same atomic size because atomic size is determined by the number of protons and this number is always constant for an element. The mass number of isotopes may however vary.
Chemical reactions involve electrons - not protons or neutrons. All isotopes of the same element have an identical number of electrons (just the number of neutrons differs) and hence the chemical properties are identical/very similar.
The main element in coal is carbon.
Isotopes of the same element have different numbers of neutrons.

Radon has four main isotopes: 210Rn, 211Rn, 222Rn, and 224Rn. Radon-222 is the most stable form.
The main difference between isotopes of the same element is the number of neutrons in the nucleus. Isotopes have the same number of protons and electrons but different numbers of neutrons, which affects their atomic mass.

The three main parts of an element are protons, neutrons, and electrons.
Niobium is found in nature. The main source is from the mineral Pyrochlore.
Candium is a fictional element used for educational purposes in chemistry experiments. Its three main uses are to teach students about the concept of isotopes, demonstrate radioactive decay, and practice balancing chemical equations.
the are Metals, Metalliods, Non-metals
An isotope of an element is same as the element in that it has the same number of protons. An isotope of an element is different from the element in that it has a different number of neutrons.
Element number 92 is Uranium and there are two main isotopes - U235 and U238. In U235 there are 92 protons so there are 235 - 92 = 143 neutrons. In U238 there are thus 146 neutrons
