They have the same number of protons and therefore the same chemical properties. But they have different numbers of neutrons and so the atomic masses are different and so are some physical properties.

Are beryllium atoms identical?

Each atom of an isotope of beryllium (or of another element) is different from the atoms of an other isotope. But all the atoms of an isotope are identical.


Is the two atoms have same atomic radius?

Two atoms of same element (for a given isotope) are identical and hence have the same atomic radius.


What does Physics Chemistry the number of atoms of one isotope of an element divided by the total number of atoms in a mixture of the isotopes mean?

If you divide the number of atoms of a single isotope by the total number of atoms, you get the ratio of that isotope. This tells you how common/uncommon that isotope is.


How is it possible for two different atoms to have the same atomic mass?

They would have to be atoms of the same element, and the same isotope of that element.

If the isotope is given for calcium what is the formula?

An isotope has extra/fewer neutrons than the original atom. So if you know the isotope you can deduce the original atoms' formula.For Ca that would be:20 protons40 mass number

What is isotope and radio isotope?

Isotopes are atoms of a particular element with different numbers of neutrons. A radio isotope is an isotope that is radioactive because the nucleus is unstable.
