Want this question answered?
Covalent bonding is typical of organic compounds which do not contain metal. Metals form either metallic or ionic bonds.
Some metals are considered precious because there harder to find and the monkey in the center of the earth might like the metal to eat at night. just jokeing the real reason is because its harder to find some of the metals and depending on the minarels in the metal
It might be metals or nonmetals in the bulb
Oh, they probably just noticed one day that the two are almost nothing alike each other, and that you'd have to be an idiot to fail to identify them as separate materials. Ever seen gold leave a big black streak when dragged across a surface? And the compound you're referring to is called iron pyrite-- "fool's gold," is a nickname. It's called "fool's gold" because you'd have to be a "fool" not to be able to tell it apart from gold. Otherwise they'd probably call it something like "nearly gold, almost anyone could fall for the similarities." But they don't. The alchemists would not have known streak-plate tests or compounds like iron pyrites as that, but they might have picked up other characteristics, such the ease or otherwise of melting the two materials. Remember that alchemists were not scientists as we would accept, but empiricists who worked on random guess-work in searching for that which cannot exist.
Of course it is. Whether you can get it to work, and exactly what 'work' means, is another matter. It is obvious that, unless one has a clear idea of the objective, and at least some scientific application of methodology (and, even for many of the greatest Alchemists, this required the dedicated work of a lifetime), one could 'do Alchemy' until the cows came home without the slightest prospect of success. Perhaps you just want a pile of gold? Remember that the Alchemists say, 'Aurum Nostrum Non Vulgi' - 'Our gold is not that of the common man'. Without wishing to cause offence (although I probably will, and for that I apologise), I feel that the way you have phrased the question suggests you might have more success in another field.
1. Because people always want as much gold. 2. Because at that time chemical and physical knowledge were very low.

Metals from groups 13-15 could be used. The metals in these mixed groups are not very reactive, and so could provide protection against corrosion.
Alchemists discovered Arsenic, Antimony, and Bismuth. The Golden Dream Alchemists, in the Middle Ages, believed they could turn ordinary metals into gold. The metallic elements silver (Ag), gold (Au) and copper (Cu) are lustrous, malleable, ductile, conductive and valuable. Each metal is used to make sculptures, jewelry and other structures. If ordinary metals are combined with other elements, you can create an alloy. Artists often work with alloys because of their durability and color. Alloys are used to make coins, costume jewelry, sculptures and other items. However, is there a way to turn alloys into one of these precious elements? To answer this question one would have to create an experiment. This experiment should be performed in a chemistry lab. Its objective is to show how alloys are made. Alchemy in the Middle Ages was a right mixture of science, philosophy and mysticism. Nowhere near operating within the modern definition of a scientific discipline. Medieval alchemists approached their craft with a holistic attitude. They believed that purity of body, spirit and mind was necessary to pursue their ideas successfully. At the very heart of medieval alchemy was the idea that all matter was composed of four elements, earth, fire, water and air. With the right combination of elements, it was theorized, any substance on earth might be formed. This included precious metals as well as elixirs to cure disease and prolong life. Alchemists believed that the 'transmutation' of one substance into another was possible, thus we have the cliche of medieval alchemists seeking to 'turn lead into gold'. Medieval Alchemists discovered Hydrochloric and Nitric acid, Potash and Sodium Carbonate. They were able to identify the elements Arsenic, Antimony, and Bismuth.
I thought it might be jessica from laguna beach, but i could be wrong
um it might be your testies..ever thought of that?
Metals, not non-metals. You might want to find a periodic table.

What transition metals might you find in a tin of pale pink paint?
In some cases it might be possible; if the particular dissimilar metals can be welded by any other means they could also be spot welded. You might need different size electrodes on each side of the joint to get a good spot weld.
it was because they thought they might accidentally kill someone and it could happen any way and then they would go to hell and they might be framed too
For example acids.
