Sample Questions and Answer Key Highlights
Below are typical questions found in an ionic bonding worksheet, along with concise answer explanations.
Question 1: Define ionic bonding.
Answer: Ionic bonding is a type of chemical bond formed when one atom transfers electrons to another atom, resulting in the formation of oppositely charged ions that attract each other.
Question 2: Which types of elements typically form ionic bonds?
Answer: Metals, which tend to lose electrons, and non-metals, which tend to gain electrons, typically form ionic bonds.
Question 3: Write the chemical formula for the compound formed between sodium (Na) and chlorine (Cl).
Answer: NaCl
Question 4: Name the ionic compound with the formula MgCl₂.
Answer: Magnesium chloride
Question 5: Draw the Lewis dot structure showing the transfer of electrons in sodium chloride.
Answer: Sodium (Na) transfers one electron to chlorine (Cl), resulting in Na⁺ and Cl⁻ ions, which are attracted to each other in the lattice.
