modern periodic table & metals and non metals
electronic structure of attoms
metals to the left of the table don't have many electrons to remove and metals towards the bottom of the table have outer electrons which are longway from the nucleus
for non metals forming ions is more difficult this is at they are to the right and have many electrons in the outer shell
react to form a full outer shell do this by looing or gaining a electrons
periodic table
6) they are called groups
5) elements with similar properties form columns
7)group number says how many electrons are in the outer shell elements in the same group are most likely to react in similar ways
4) easy to work out which elements are metals and which are non metals metals are to the left and non metals are to the right
8)if you know the properties of one element you know the properties of all elements in that group
3) if it wasn't for the periodic table organising everything would be hard
9)you can make predictions about trends in reactivity
2)in the periodic table the elements are laid out in order of increasing atomic protons number means they are in patterns in the properties of the elements
10) rows are called periods each new period represents another full shell
1) there 100ish elements which all materials are made up of
most elements are metals
2) there towards the bottom and to the left of the periodic table
3) most elements in the periodic tabel are metals
1) metals are elements which can form positive ions when they react
4) non metals are at the far let and top of the periodic table
5) non metals don't generally form positive ions when they react
physical properties
all metals have metallic bonding which causes them to have similar basic physical properties
great at conducting heat and electricity
high boiling and melting points
they are strong can be bent or hammered into different shapes
non metals don't have metallic bonding don't tend to exhibit the same properties as metals tend to be dull looking more brittle arnt always a solid at room temperature
