About when did the first blacksmith live?
That is a very hard question to answer. Man has been using metal for a very long time. Gold, silver. and copper are thought to be the some of the first metals mankind learned to use. Blacksmiths work mainly with iron or steel. Very little iron occurs in its natural state. Iron nickle meteorites were probably used by very early people to form tools. As you can imagine there would be very little metal to work with. Current thinking is that potters using iron rich dyes found puddles of metal after the kilns cooled off. These people would of probably use this metal for decoration and art. They would of been the very first blacksmiths. That could of been as long ago as 6ooo BC or even earlier then that. Every time scientists think that they have a firm grip on the dates new evidence is found pushing the dates even further back.
Will a 60watt light bulb melt a chocolate?
Under the right circumstances, yes. So will, for example, a 15 watt soldering iron. It just won't melt very much. It is not the wattage that determines the temperature, it is the insulation (or lack thereof) around the bulb and chocolate that determine it.
How fast can a medieval battle axe split or destroy a metal shield?
The simple answer is not very well, "metal" shields were actually still mostly wood, but the key differences are that the edges are protected my metal rims, and a metal boss (lump in the middle) is used to improve bashing in close contact. The front of a shield is quite difficult to hack into when you consider that properly trained swordsmen would use it to deflect, rather than just block. The real weakness of a wooden shield was any time the opponent's weapon caught an edge, because splitting would (wood?) occur at that moment.
What were the materials ancient Greeks used to make chariots?
The first section is the wheel hub. The Romans chariots at first used carved/turned wooden hubs, and later moved on to cast metals such as bronze and copper. Early chariots had very little metal on them, but later ones had a LOT of metal depending on the owner's position in society or the use to which the chariot was intended to be put.

Is sodium shiny when it is cut?
yes! very fun BUT DANGEROUS to put in water
How many electrons do alkali metals have on there auter shell how does this affect the properties of a metal?
Alkali metal have only one electron on the external shell; the are very reactive and form cations.
Is an alkali metal a base?
The metal itself, no. But after reacting with water or something containing water it produces a very strong base.
What metal is alkali metal?
This is the first column in the Periodic Table. There are six metals that are "Alkali Metals" and six that are "Alkali Earth Metals". The Alkali metals are:LithiumSodiumPotassiumRubidiumCaesiumFranciumThese metals get more reactive as you go down the list...Hope I helped :D
What element is used to treat depression?
A medicines used to treat depression is often referred to as lithium but it is NOT the element lithium. Taking pure lithium metal would be very dangerous as it is a very reactive alkali metal.
