Analogies are a powerful way to help students understand the complexities of chemistry. We can use different classification systems from everyday life to help students understand how the periodic table classifies elements. The position of hydrogen can often lead to confusion as different versions of the periodic table place it differently: at the top of group 1 or 7 or somewhere in between. The point to emphasis here is that hydrogen is an anomaly. It is a non-metal with an electronic structure similar to group 1 metals. Therefore chemists sometimes struggle to know where to place it.

A vertical column in the periodic table. Members of a group typically have similar properties and electron configurations in their outer shell.Now take a look at a group of metals or non-metals such as the alkali metals or halogens. Demonstrate how the properties change as you go down the group. This can be done by looking up data such as melting points, and density and/or with practical demonstrations. Encourage students to look for patterns in reactivity and compare this reactivity to the position of the element in the periodic table. A percentile rank for the political stability of the top producing country, derived from World Bank governance indicators.

Introduce students to a range of different elements in the table by asking them to classify them as metals or non-metals. Then ask them to find the symbol on the periodic table. After repeating this with a number of elements, they will soon start to build up a picture and discover that metals are on the left-hand side of the table and the non-metals on the right. The elements in a group show patterns in their physical properties such as melting or boiling point, thermal conductivity and density. They have similar chemical reactions with, for example, oxygen. An integrated supply risk index from 1 (very low risk) to 10 (very high risk). This is calculated by combining the scores for crustal abundance, reserve distribution, production concentration, substitutability, recycling rate and political stability scores. Commercial use of the Images will be charged at a rate based on the particular use, prices on application. In such cases we would ask you to sign a Visual Elements licence agreement, tailored to the specific use you propose.Describe and model the structure of the atom in terms of the nucleus, protons, neutrons and electrons; comparing mass and charge of protons neutrond and electrons. Next move onto contexts that show a link between a physical attribute and a property. A good example is the string section of an orchestra, which has different-sized instruments. The smallest instruments sit at one side and play the highest notes, while the biggest are at the other side and play the lowest notes. A horizontal row in the periodic table. The atomic number of each element increases by one, reading from left to right. The percentage of a commodity which is recycled. A higher recycling rate may reduce risk to supply.

The mass of an atom relative to that of carbon-12. This is approximately the sum of the number of protons and neutrons in the nucleus. Where more than one isotope exists, the value given is the abundance weighted average. Odd one out’ activities require students to justify their choices, providing you within an insight into their thinking. For example, ask them to look at the images above and decide which one doesn’t fit. Progression to 14–16 The percentage of an element produced in the top producing country. The higher the value, the larger risk there is to supply. W. M. Haynes, ed., CRC Handbook of Chemistry and Physics, CRC Press/Taylor and Francis, Boca Raton, FL, 95th Edition, Internet Version 2015, accessed December 2014.

You can also use the periodic table to develop students’ research and presentation skills. Assign each student a different element and ask them to find out and present key pieces of information to the group. Together you can build a class periodic table with this work. The RSC interactive periodic table is a good place to start researching. Start with analogies that students are likely to be familiar with, before moving on to less familiar examples. The layout of supermarkets is a good place to start. In a supermarket, food is grouped in different aisles according the characteristics and properties of the food – for example: fruit and vegetables, bakery, meat, dairy, cereals.
