All substances on earth are made up of atoms.
mostly metals
that why you gi to school :D
All of them are metals. Those are in the d block.
Metals come from two different places. Most come from the earth they are natural metals other can be mixes of these metals called alloys. If you look at the periodic table you will see a separate section of the table usually below that has all the man made elements but only a few of these are man made metals. This is a brief answer.
conductors are generally are made of metals and naturally metals are of shiny and so u can tell that all conductors of heat shiny
Fire bells are made from metals so that the bell can be heard for long distances. If the bell was made from wood the sound would not carry or be very loud at all.
No metals are being made on the Earth (metals are all elements) so whatever there were at the start is whatever there are now.
Yes, most alloys are good conductors of heat and electricity. This is because alloys are made by mixing different metals together, which creates a structure that allows the flow of heat and electric charge more easily compared to pure metals.
Metals of course dude.
NOT all metals are magnetic
All metals are chemical elements.
The crust which is about 7 miles thick contains the all of the element metals we have discovered so far because no one has ever drilled all the way through the crust.
