2
Q
Describe how elements with similar properties are placed in the periodic table
A
Elements in the same group have the same chemical properties, this is because they have the same amount of outer electrons
3
Q
Explain why elements in the same group have similar properties and how to use the periodic table to predict the reactivity of elements
A
They have the same electronic configuration
4
Q
Define the early attempts to classify elements
A
Before protons, neutrons and electrons were discovered, elements were arranged in order of atomic weight (which is now called atomic mass)
