Ionic Bonding
Chemistry ⇒ Chemical Bonding and Structure
Ionic Bonding starts at 8 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Ionic Bonding.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 10
A compound is formed between element X (group 1) and element Y (group 7). What is the formula of the compound?
A student dissolves table salt (NaCl) in water. Explain why the solution conducts electricity.
Describe the role of valence electrons in the formation of ionic bonds.
Describe the structure of an ionic compound.
Describe what happens to the electrons when sodium reacts with chlorine to form sodium chloride.
Explain why ionic compounds conduct electricity when molten but not when solid.
