Ionic Bonding - AS level 0.0 / 5 ? ChemistryBonding & shapesASAQA Created by: Jess1907Created on: 09-09-19 16:36 What is a compound? Two or more DIFFERENT atoms bonded together 1 of 12 Define ionic bonding oppositely charged Ions that are held together by electrostatic attraction in a lattice Between a metal and a non-metal. 2 of 12 How are Ions formed? When one or more electrons are transfered from one atom to another. 3 of 12 Write the sulfate ion SO4 ^2- 4 of 12 Write a hydroxide ion OH- 5 of 12 Write a nitrate ion NO3 - 6 of 12 Write a carbonate ion CO3 ^2- 7 of 12 Write an ammonium ion NH4+ 8 of 12 What is the overall charge of any compound? zero 9 of 12 Can ionic compounds conduct electricity? Only when molten as the ions are free to move around and carry a charge 10 of 12 Do they have a low or high melting point? Why? High - because they have strong electrostatic forces so high amount of energy is needed to break them 11 of 12 Are they soluble? They are in polar solvent as the charged particles pull the ions away from the lattice 12 of 12
