Chemical Bonding Quiz
The table below shows the number of protons in elements P and Q.
The reactivity of the reaction between element Q and chlorine is higher than the reactivity of the reaction between element P and chlorine.
State the group that elements P and Q belong to in the Periodic Table.
State the period that element Q belongs to in the periodic table.
Element P reacts with chlorine to form a compound.
What type of compound is formed?
Write the formula of the compound that is formed.
Draw the electron arrangement of the compound that is formed.
Element Q reacts more vigorously than element P. Explain this occurrence in terms of the electron arrangement.
Element R has a proton number of 2 and a nucleon number of 4. Explain why element R does not react with element Q.
