Ionic, Compound and Isotopes
1 Atomic number and mass number describe an atom
1.1 Numbers that tell you how many of each kind of particle an atom has:
1.1.1 The Mass Number
1.1.1.1 Total number of protons and neutrons
1.1.1.1.1 Top Number of the element
1.1.2 The Atomic Number
1.1.2.1 Number of protons
1.1.2.1.1 Bottom Number of the element
2 To get the number of neutrons, just subtract the atomic number from the mass number to get the relative mass.
3 Compounds are chemically bonded
3.1 Compounds are formed when atoms of two or more element are chemically combined together
3.2 It’s difficult to separate the two original elements out again
4 Isotopes are the same except for an extra neutron or two
4.1 A favourite exam question “Explain what is meant by the term isotopes”
4.1.1 Isotopes are: different atomic forms of the same element, which have the SAME number of PROTONS but a DIFFERENT number of NEUTRONS
