C2 (ionic bonding, limitations of the partical matter, metallic bonding,…
C2
ionic bonding
oppositely charged ions - 1 positive and 1 negitive non-metal
atoms always want a full outer shell
atoms either gain or lose a electron to acheive a full outer shell
lose electron = positive ion
gain electron = negitive ion
all metals lose electrons
all non metals gain electrons to form negative ions
ions will bond together to get a overall charge of 0
naming ionic compunds
the metals is named 1st
the non-metal is named 2nd
properties of ionic compounds
ionic lattice
ions of opposite charges are attracted to each other by electrostatic attraction
representing ionic compounds
dot and cross diagrams
3D models
Ball and stick models
limitations of the partical matter
particals aren't solid or inelastic
particales aren't spheres, they are atoms/ions/molecules
doesent show the forces between the patical so no way of knowing how strong they are
distance between the particales are not to scale
metallic bonding
metallic elements and alloys that share delocalised electrons
covalent bonding
non-metallic elements and compound that shair pairs of electrons
