1.4: Ionic Bonding and Ionic Compounds Flashcards
Q: What is an ion?
A: An ion is a charged particle formed when an atom loses or gains electrons.
Q: What type of ion do metals form?
metals = …
A: Metals lose electrons to form positively charged ions (cations).
Q: What type of ion do non-metals form?
non-metals: non…
A: Non-metals gain electrons to form negatively charged ions (anions).
Q: How does ionic bonding occur?
A: Ionic bonding occurs due to the strong electrostatic attraction between oppositely charged ions.
Q: What is the structure of ionic compounds called?
starts with a l
A: The structure is called a lattice, a regular arrangement of **alternating positive **and negative ions.
Q: Why do ionic compounds have high melting and boiling points?
A: The strong electrostatic forces between ions require a lot of energy to break.
Q: Why do ionic compounds conduct electricity when molten or dissolved?
A: The ions are free to move, allowing them to carry an electric current.
Q: Why are ionic compounds brittle?
When the lattice is disrupted,
A: When the lattice is disrupted, like charges repel, causing the structure to shatter.
Q: Give an example of a compound formed by ionic bonding.
A: Sodium chloride (NaCl), formed when sodium loses an electron to chlorine.
Q: What happens during the formation of MgO?
A: Magnesium loses two electrons to form Mg²⁺, and oxygen gains two electrons to form O²⁻, forming MgO.
