Cobalt is a meta element. Atomic Mass of it is 59.
The atomic number of Cobalt is 27.
Atomic number 27 : Cobalt Atomic number 28 : Nickel Atomic number 29 : Copper Atomic number 30 : Zinc Atomic number 31 : Gallium
When you talk about an isotope, the number that follows the element name is the number of neutrons. So, 27 neutrons. Every cobalt has 27 protons. If the number of protons were to change (which doesn't happen naturally), then it would no longer be cobalt. Having the same number of protons as neutrons, however, would not make this an isotope. What you are talking about is normal cobalt.
The atomic weight of nickel lies in between that of cobalt and copper.
The element with mass number 27 is cobalt, which has 27 as its atomic mass.
The atomic number of Cobalt is 27.
Cobalt has a lower atomic mass than lead. The atomic mass of cobalt is approximately 58.93 g/mol, whereas the atomic mass of lead is about 207.2 g/mol.
On the periodic table, lead (Pb) has an atomic weight of 207.2, and cobalt (Co) has an atomic weight of 58.93320.
Cobalt, is in the metal family. The atomic number for the element of cobalt, (word steaming from the German meaning for evil spirit, and goblin) is twenty seven.
The atomic weight of cobalt is 58.933.
Cobalt has an atomic mass of 58.933195(5) while nickel has an atomic mass of 58.6934(4). Nickel has the lower atomic mass.
Interestingly, nickel has a lower atomic mass (58.693) than cobalt (58.933), even though cobalt has a lower atomic number (27) than nickel (28).
Cobalt (Co) has a smaller atomic mass than Lead (Pb). Cobalt's atomic mass is only 58.9332 while lead's is 207.2.
The average atomic mass for cobalt is approximately 58.93 atomic mass units. It is calculated by taking into account the different isotopes of cobalt and their relative abundance in nature.
A typical atom of cobalt contains 32 neutrons. Cobalt's atomic number is 27, so that's 27 protons. Its average atomic mass is about 59, so 59-27=32. Note: different isotopes of cobalt will have either more or less neutrons than 32, but most likely, cobalt's most abundant isotope has 32. The atomic mass value on the periodic table, which is 58.933, is a weighted average of all cobalt's isotopes.
The atomic number of Cobalt (Co) is 27. The atomic weight of Co is 58.9332 grams per mole. See the Web Links to the left of this answer for a periodic table with more information about this element!
The atomic mass of cobalt (Co) is approximately 58.93 atomic mass units (amu).
