the two atoms belong to two different elements
Isotopes are atoms of the same element with different numbers of neutrons in their nuclei, resulting in different atomic masses. This is how there can be two different atoms of iridium.
Two atoms with the same number of protons but different numbers of neutrons are called "isotopes".
If two atoms are isotopes, it means they have the same number of protons but different numbers of neutrons. Thus, they have the same atomic numbers, but different atomic masses.
They are isotopes of each other.
when the protons changes, then the two atoms belong to two different elements.
No. The atomic number of an element is determined by its number of protons. If two atoms have different numbers of protons, they have different atomic numbers and are different elements.
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.
These two atoms are isotopes of each other. They have the same atomic number (protons) but different mass numbers due to their different numbers of neutrons. This means they will differ in terms of stability and possibly some properties, but they will have the same charge and occupy the same position on the periodic table.
Different isotopes of bromine have different numbers of neutrons, resulting in different mass numbers. Bromine-79 and bromine-81 are the two most common isotopes of bromine, with mass numbers of 79 and 81, respectively.
When two atoms appear to have the same mass number, it means they have the same total number of protons and neutrons. However, they may have different atomic numbers, meaning they are different elements. This can occur with isotopes, where atoms of the same element have the same mass number but different numbers of neutrons.
One of two or more atoms having the same atomic number but different mass numbers.
