Chemistry Flashcards
3 Types of intermolecular forces
Van der Waals, Dipole-Dipole, Hydrogen Bonding
Properties of Metallic bonding
Ionised atoms, positive ions, outer shell electrons delocalised
Properties of covalent compounds
Low melting and boiling points
Soft or brittle solid forms
Poor electrical and thermal conductivity
Covalent bonding
A shared pair of electrons attracted to the nucleus of each atom
Bond strength and length
Higher energy and shorter length = stronger bond
Ionic bonding
Opposites attract to give you a lattice structure
What reacts in ionic bonding?
Metal and a non metal
Relative mass and relative charge
Proton, 1 and +1
Neutron, 1 and 0
Electron, 1/1840 and -1
spdf example
1s2, 2s2, 2p6, 3s2, 3p6, 4s2, 3d10
Mol equation
Mols = Mass / Molecular Mass
