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 9

Describe the process of ionic bond formation between magnesium and oxygen.

Describe the role of valence electrons in the formation of ionic bonds.

Describe what happens to the electrons during the formation of sodium chloride (NaCl).

Explain why ionic compounds are usually soluble in water.

Explain why magnesium forms a Mg²⁺ ion and not Mg⁺ in ionic compounds.

Explain why solid ionic compounds do not conduct electricity, but their solutions do.

Sodium (Na) has one electron in its outer shell. What will happen to this electron during ionic bonding with chlorine (Cl)?

State one reason why ionic compounds are brittle.

What is the charge on the oxide ion (O) in ionic compounds?

What is the formula of the ionic compound formed between barium (Ba) and sulfur (S)?

What is the formula of the ionic compound formed between calcium (Ca) and bromine (Br)?

What is the formula of the ionic compound formed between lithium (Li) and nitrogen (N)?

What is the formula of the ionic compound formed between magnesium (Mg) and chlorine (Cl)?

What is the name of the ionic compound with the formula Na₂O?

What is the total number of electrons transferred when two sodium atoms react with one oxygen atom to form sodium oxide?

What type of ion is formed when a non-metal gains electrons?

A student dissolves an ionic compound in water and observes that the solution conducts electricity. Explain why this happens.

Calculate the total number of electrons transferred when three magnesium atoms react with two nitrogen atoms to form magnesium nitride (Mg₃N₂).

Consider the following scenario: A compound is formed when element X (with 2 valence electrons) reacts with element Y (with 7 valence electrons). Predict the formula of the ionic compound formed and explain your reasoning.

Describe how the arrangement of ions in a crystal lattice contributes to the high melting point of ionic compounds.
