GCSE Chemistry: Isotopes
All atoms of a particular element have the same number of protons, but they can have different numbers of neutrons.
Can you calculate the number of neutrons in an isotope?
What is GCSE Chemistry: Isotopes?
"Isotopes are varieties of an element that have the same number of protons but different numbers of neutrons in their nuclei."
Isotopes are atoms of the same element with the same number of ____ but different numbers of ____.
Why are isotopes chemically identical even though they have different masses?
An atom has 6 protons and 7 neutrons. What is its mass number?
Isotope Facts
Isotopes are atoms of the same element with different numbers of neutrons.
They have the same atomic number but different mass numbers.
They have identical chemical properties because they have the same number of outer electrons.
Relative atomic mass (Ar) is an average value that takes into account the abundance of the isotopes of the element.
