Guida verificata passo dopo passo1
Recall that isotopes of an element have the same number of protons but differ in the number of neutrons in their nuclei.
Understand that protons define the element's identity, so all isotopes of titanium must have the same number of protons.
Recognize that electrons can vary in ions but do not define isotopes; isotopes differ in the nucleus, not the electron cloud.
Quarks are fundamental particles inside protons and neutrons and are not used to distinguish isotopes.
Therefore, the difference in isotopes of titanium on any planet is due to the number of neutrons.
