Keep in mind that the Atomic Mass of an element is based on an average of relative abundance of stable isotopes. Nickel has several stable isotopes and Cobalt I believe has only one stable isotope. The weighted average proportionally to the relative abundance of the several Nickel isotopes is less than the average of Cobalt's isotope(s). So basically Though Nickel has a greater atomic number and the trend is for this to correlate with atomic mass because nickel exists in relatively large proportion as a lighter stable isotope Nickels average atomic mass is less than Cobalt's atomic mass. Google about relative abundance and calculating atomic mass to find all sorts of interesting things!
In the Periodic Table, the elements are arranged by atomic number (number of protons), not atomic mass. The number of protons is an important factor in how an element behaves chemically.
Atomic mass is determined by number of protons plus number of neutrons in an atom. Many elements have isotopes which have different number of neutrons. Typically, the increase in atomic number will result in atomic mass increasing, but Cobalt has enough naturally occurring isotopes which make the average atomic mass is slightly higher than the average atomic mass of Nickel.
No. although Nickel has more protons in its nucleus, Cobalt has more neutrons on average.
Average atomic mass of Cobalt : 58.9 grams/mole
Average atomic mass of Nickel : 58.7 grams/mole
Elements are arranged according to atomic number.So Co is placed before Ni.
Co has 27 protons ans Ni has 28.So Cobalt will be before Nickel.Cobalt has less protons that why placed earlier on the table.
1. Co is the chemical symbol of cobalt.2. CO is the chemical formula of carbon monoxide.

W on the Periodic Table is Tungsten. One may wonder why it is not't T. This is because W is from "wolfram ". It refers to the fact that tungsten was originally obtained from the mineral wolframite)
Te and I,Ar and K,Co and Ni
CO2 is a molecule called carbon dioxide. Periodic table lists elements and any molecules or compounds like the one asked in the question.
The chemical symbol Co is the symbol for cobalt. Don't confuse this with CO, which is carbon monoxide.

The 27th element is Cobalt (Co).
You won't find charcoal in the periodic table. But charcoal is mostly composed of carbon atoms. And the chemical symbol for carbon is simply "C".
Co
Unknown to Mendeleev, Lothar Meyer was also working on a Periodic Table. Although his work was published in 1864, and was done independently of Mendeleev, few historians regard him as an equal co-creator of the periodic table.
If you mean on a periodic table ... ---- Co= Cobalt 27 Co 58.933 ----
