1. Transition Elements
Trends

2. Review What do you know about the properties of metals?
What do you know about the properties of alkali metals?

3. How do transition elements compare to Alkali
Most have higher melting points then group 1
Higher densities (none float on water)
Stronger and Harder
Much Less Reactive
Can form multiple charged ions
i.e +2, +3, or even +4 ions
These ions can be different colors

5. Atomic Size (Radius) Decreases from left to right
WHY?
Increases down a period, but it is very difficult to observe in transitions elements

6. Transition Metals Form Alloys
An alloy is a mixture of a metal with other elements (metals or non–metals).
The point about using alloys is that you can make up, and try out, all sorts of different compositions until you find the one that best suits the required purpose in terms of tensile/compression strength, malleability, electrical conductivity or corrosion resistance etc

7. Steel – an Iron Alloy
Steel alloys of varying strength and anti–corrosion properties are used in thousands of products and constructions
reinforcing rods in concrete buildings
bridge girders
car engines
appliances from washing machines to electric kettles
saucepans
tools like chisels and very hard drill bits,
ship hulls

8. Brass- an alloy of Copper and Zinc
It is a much more hard wearing metal than copper (too soft) and zinc (too brittle) and is more malleable than bronze for 'stamping' or 'cutting' it into shape.
Brass is used to make fixtures and fittings like door knobs, screws, hinges, springs and musical instruments like trumpets, trombones, French horns,

9. TITANIUM is a strong metal that has a low density and a high resistance to corrosion which makes a good structural material.
Titanium alloys are amongst the strongest lightest of metal alloys and used in aircraft production.
As well as its use in airplane it is an important component in nuclear reactor alloys and for replacement hip joints because of its light and strong nature AND doesn't corrode easily.
Titanium alloys are superior to aluminum alloys, but titanium alloys are more expensive

10. Transition metals and electrons
Transition metals get their properties from electrons
Remember the transition metals are apart of the d block – their electron configurations end in the d orbitals
Remember the inner transition( Lanthanide and actinides) end theirs with the f orbitals

11. Another way to do electron configurations
Box and Arrow Method
This sublevel configuration can be broken down into orbitals (boxes). 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p
Reminder each orbital can hold 0,1, or 2 electrons

12. When we draw electrons, we use up and down arrows
When we draw electrons, we use up and down arrows. So, if an electron is paired up in a box, one arrow is up and the second must be down. When filling sublevels other than s, electrons are placed in individual orbitals before they are paired up
