Periodic table

L.G. To understand and identify patterns in the periodic table.


Keywords:

Metal - A shiny element that conducts heat and electricity

Non-Metal - A chemical element that lacks the properties of a metal

Metalloids - Chemical elements with properties in between those of metals and non-metals


The periodic table is in an order/is a sequence.


Metals 

Non-Metals 

  • Solid

  • Shiny, malleable, ductile and sonorous

  • Good conductors of heat and electricity

  • Have high melting points and high density

  • Usually gas or liquid

  • Dull, brittle, and are not sonorous (Makes a ringing sound when hit)

  • Poor conductors of heat and electricity

  • Have low melting points and low density. 


Metals can easily give away electrons. Non-metals can easily recieve electrons

Groups (Vertical):

Group 1: Has 1 electron in the outer shell

Group 2: Has 2 electrons in the outer shell

Group 3: Has 3 electrons in the outer shell

Group 4: Has 4 electrons in the outer shell

Group 5: Has 5 electrons in the outer shell

Group 6: Has 6 electrons in the outer shell

Group 7: Has 7 electrons in the outer shell

Group 8: Has 8 electrons in the outer shell


Periods (Horizontal):

Period tells us how many electron shells

  • Each perriod indicates how many electron shells an element has

  • E.g. Elements in period 3 will have 3 electron shells.
