Year 6 Revision Assessment date: Name: Subatomic particle Location What is an atom? Circle the objects below that are made out of atoms Atoms are made from three subatomic particles 1. 2. 3. Complete the table below Subatomic particle Location Charge Mass For the element below, complete the following (you will need your periodic table): What is the name of the element? What is the mass number? What is the atomic number? How many protons? How many neutrons? How many electrons?

Atom Element Compound Mixture For the element on the previous page. Draw the electron configuration. Label the nucleus and shells. Define the following: Atom Element Compound Mixture Which group are the alkali metals in? Where is this group on the periodic table? Name the state and draw the particle diagrams for the following substances in different states in the boxes below. Label the state changes between each state using arrows. Oxygen State: Green tea State: Table State: Give the names of the alkali metals starting from MOST reactive to LEAST reactive LEAST 1. 2. 3. 4. 5. 6. MOST Give one similarity between the alkali metals electron configuration Give one difference between the alkali metals electron configuration

Variable Description Independent Dependent Control How do the similarities and differences of the alkali metals you have listed affect the reactivity of these metals? Name three methods of separation that you have seen in lessons: 1. 2. 3. 4.. Describe the method for separation technique 1. Describe the method for separation technique 2. Describe the method for separation technique 3. Describe the method for separation technique 4. Describe the following variables Identify a hazard in the picture below. How could you prevent that hazard from happening? How would you treat it if it did happen? Variable Description Independent Dependent Control
