IONIC BONDING. HOW DOES IT WORK? Ionic bonding takes place between metals and non-metals Metal atoms try to attain noble gas strucure (full outer shells)
Formation of compounds. What happens when a piece of burning sodium is placed in a gas jar of chlorine? sodium chlorine + sodium chloride.
Positively charged ions and negatively charged ions are attracted to each other and this attraction is the basis of ionic bonding.
Magnesium has metallic bonding. (i)Draw a diagram to show what is meant by metallic bonding. Label the diagram. [2] (ii) Why is magnesium a good conductor.
The chemical nature of cells
Structure and bonding Atomic structure Atomic structure Atomic orbitals Atomic orbitals The electronic structures of atoms The electronic structures of.
Electronegativity. What is electronegativity? The ability of an element to attract bonding electrons to itself What does that mean?
