Metal X is in Group 2 of the Periodic Table, below calcium. The letter X is used in place of its chemical symbol. When X is heated in bromine vapour, it forms an ionic compound.
Predict whether X is more reactive or less reactive than calcium. Explain your answer.
Give the formula of the compound formed when X reacts with bromine.
Write a balanced symbol equation for the reaction between X and bromine.
