Study Notes
Isotopes and Atomic Mass
- The relative atomic mass of titanium is not provided in the given sample.
- There are multiple isotopes of magnesium, with the exact number not specified.
- The differences between one atom of each of the magnesium isotopes lie in the number of subatomic particles, specifically neutrons.
- Isotopes are atoms of the same element that have the same number of protons (atomic number) but differ in the number of neutrons, resulting in different mass numbers.
- All atoms of element E in the sample contain the same number of protons, which is not specified.
- The isotope of element E with a mass number of 10 is not specified by its atomic number or number of neutrons.
- The isotope of element E with a mass number of 11 is not specified by its atomic number or number of neutrons.
