What are two atoms that are isotopes?
I think Hydrogen atom and it's isotopes-Protium, Deuterium and Tritium
Isotopes are atoms of the same element (i.e., having same atomic number) but have different atomic mass. e.g.: Hydrogen (atomic number=1) has three isotopes, viz. protium (atomic mass=1u), deuterium (atomic mass=2u) and tritium (atomic mass=3u).
Isotopes are atoms of the same element ,i.e., atoms that have the same number of electrons in their outer orbit, also called atomic number, and different mass number(the total sum of protons and neutrons present in the nucleus of the cell) E.g.- Oxygen[ Atomic number(Z) =8] has 3 isotopes of atomic masses(mass no.) 16,17 and 18.
isotopes are atoms of the same element (i.e. they have the same atomic number) that have different mass numbers due to the different number of neutrons in the nucleus. Carbon has 3 isotopes, 12 13 14 C C C 6 6 6 i.e. carbon-12 carbon-13 and carbon-14.
Isotopes are atoms of the same element that have a different atomic mass; basically the atoms have the same number of protons but may have more or less neutrons in the nucleus. The best known example of an isotope would be Carbon-14 since it is radioactive and is used for carbon dating and half-life. So to answer your question compare and contrast Carbon-12 (i.e. "normal" Carbon) and Carbon-14.
