yes it can
The protons and neutrons of cobalt just like any other element are located in the nucleus whereas the electrons are located in the energy shells.
Lead is an element. The fact that it comes as shot, or fishing weights, or curtain weights, or some other form does not make it any thing other than an element. When it is mixed with other substances to create lead crystal, then it is a mixture.
It's readily available at modest cost. Cobalt is fairly common, and it is found in quantities that make it commercially recoverable in over a dozen countries. It does not appear to be in short supply. There is a bit of work involved in winning the metal, but recovery does not require exotic and grossly expensive processes. Cobalt is mined as an arsenide only in Canada and Morocco. In other locations, cobalt is recovered as a commercially separated byproduct of copper or nickel production. Cobalt is a necessary metal for modern industry. It has a wide variety of uses from an alloy forming element to a compound forming element that has applications as a pigment or a catalyst. There are a variety of other uses aside from these. Need links? You got 'em.
H2 is an element as it does not include any other elements from the Periodic Table.
Any other gas.
Yes. Cobalt (Co) can be reacted with most elements. Here are a few reactions:Cobalt + Oxygen --> Cobalt OxideCobalt + Sulphur --> Cobalt SulphateCobalt + Iodine --> Cobalt IodideCobalt + Chlorine --> Cobalt Chloride
The protons and neutrons of cobalt just like any other element are located in the nucleus whereas the electrons are located in the energy shells.
It is used in paints, medicines, meteors, and Pottery.
rubidium, magnesium, cobalt, argon.
Copper is an element in and of itself - you can't "mix" any other substances to get it. Copper is mixed with zinc to make brass, or with tin to make bronze.
Lead is an element. The fact that it comes as shot, or fishing weights, or curtain weights, or some other form does not make it any thing other than an element. When it is mixed with other substances to create lead crystal, then it is a mixture.
The number of neutrons in any element is equal to mass number - atomic number. So,number of neutrons in cobalt is = 58 - 27 = 32. therefore, number of neutrons in cobalt is 32.
There are no compounds in Cobalt. It is completely impossible, because Cobalt is an element, and compounds are made up of elements. If this is what you meant to ask, then there a a lot of compounds with Cobalt in them. One example is Cobalt (III) Fluoride, chemical formula CoF3. Any compound with a "Co" (the "C" must be capitalized and the "o" must lowercase) in it contains Cobalt.
Oxygen is an element and don'y contain any other element.

No. Kryptonite is a nobel gas, and doesn't react with any other elements.
