Metals and non metals make up all of the periodic table and they are arranged in a certain order.
Electrons exist in shells around the nucleus and have different configurations and layouts based on the element in the periodic table. Electrons are also very important in bonding.
Bonding describes how metallic and non metallic elements of the periodic table exist as elements or combined together to form new compounds with different properties.
Metallic bonding is the bonding found in metals, positive metal ions surrounded by a sea of delocalized electrons.
States of Matter are the different forms that elements, compounds and mixtures will exist in as either solids, liquids or gases depending on how close their particles are.
Oxidation states are a measure of the difference in the number of protons and electrons in an ion or atom
The transition metals is a term given to the group of metals that occupy the centre of the periodic table. They are known as the transition elements as they bridge the gap between group 2 and 3. They are all metals, form coloured compounds and can act as catalysts with variable oxidation states.
The lanthanides are a series of chemicals in the expanded periodic table that have an expanded number of orbitals beyond that of the transition metals. The lanthanides are mostly soft metals with their hardness increasing across the period. Whilst they are metals and can conduct electricity the lanthanides have a relatively high resistivity.
Transition metals are found in the centre of the periodic table between group 2 and 3. As part of the extended periodic table it makes up 10 groups from 2 to 3 and each of the metals has metallic bonding and a unique set of properties due to the d shell sub orbital of electrons.
