ionic bonding Flashcards
How are ions formed?
Through the loss or gain of electrons
What type of force holds positive and negative ions together?
Electrostatic forces of attraction
When is an ionic compound formed?
When oppositely charged ions come together and form ionic bonds
What is the ionic formula of ammonium?
NH₄+
What is the ionic formula of carbonate?
CO₃²⁻
What is the ionic formula of hydroxide?
OH⁻
What is the ionic formula of nitrate?
NO₃⁻
What is the ionic formula of sulphate?
SO₄²⁻
What are ionic crystals?
Giant lattices of ions
What is the electrical conductivity of ionic compounds like?
They conduct electricity when they’re molten or dissolved as the ions are free to move and carry charge
What is the melting point of ionic compounds like?
They have high melting points as the lattices are held together by strong electrostatic forces
What is the solubility of ionic compounds like?
They dissolve in water. Water molecules are polar so the water molecules pull the ions away from the lattice and cause it to dissolve
