Isotopes
Isotopes are atoms of the same element with different numbers of neutrons
Isotopes of the same element have...
- different masses
- the same number of protons and electrons
- Different numbers of neutrons in the nucleus
Isotopes are described with two numbers
- rthe atomic number- the number of protons in the nucleus
- The mass number- the number of protons and neutrons in the nucleus
- Different isotopes of an element will have the same proton number but different mass numbers
Different isotopes of the same element react in the same way
- Chemical reactions involve electrons, not neutrons
- Neutrons make no difference to chemical reactivity
