Atoms with the same atomic number are all atoms of the same element. However, if the atoms have different molecular weights, they are isotopes of the same element.
isotopes Atoms of the same element are called Isotopes. they have the same number of atoms (i.e. same atomic number) but different number of neutrons
If they have the same atomic number but different mass, then they have a different number of neutrons, and they are called ISOTOPES.
These atoms are called isotopes and they have a different number of neutrons.
They are called isotopes. eg we have different isotopes of carbon
They are called as isotopes in which mass number differ by emmision of radiation
Atoms with the same number of protons but different mass numbers are called isotopes. Isotopes have the same atomic number but different atomic weights due to variations in the number of neutrons in the nucleus.
the number of protons in an atoms nucleus is called atomic number
They are called isotopes of the same element
Atoms that have the same number of protons but different weights are called isotopes. Isotopes of an element have the same atomic number (number of protons), but a different atomic mass (sum of protons and neutrons) due to varying numbers of neutrons.
Atoms of same element with same atomic number,which have different mass number is called isotops.
The sum of protons and neutrons in the atomic nucleus is called "mass number"; this value is different for each isotope.
Isotopes of an element have different masses but the same atomic number. Isotopes have the same number of protons and electrons but different numbers of neutrons in their nuclei.
