1 Revision Quiz Atomic Theory 1 1. Draw a simple picture of an atom show the three main particles2. What charge does an atom have?3. What charge does a neutron have?4. What charge does a proton have?5. What charge does a electron have?Protons and neutronselectronsNo chargeNo chargepositivenegative
2 Revision Quiz Atomic Theory 2 1. What particle has “ no mass”2. What is the mass number?3. What is the atomic number4. How is the number of neutrons calculated?5. Why are atoms neutral?electronNumber of protons + number of neutronsNumber of protons (and number of electrons in a neutral atom)Mass number – Atomic numberSame number of positive and negative particles. They cancel each other out.

5 Revision Quiz Atomic Theory 5 1. What do we call atoms with the same atomic number but different mass number?2. These particles have the same number of which particles?3. Why is the relative atomic mass rarely a whole number?4. What do we call columns in the Periodic Table?5. What do we call rows in the Periodic Table?isotopesNumber of protons (+ number of electrons in a neutral atom)An average that takes into account the percentage abundance of each isotopegroupsperiods
