The electron configuration of cobalt is [Ar]3d7.4s2.
The element with atomic number 27 is cobalt and its electronic configuration is [Ar] 4s2 3d7
Ar 3d7 4s2
The element cobalt has 27 protons. Since the sum of the number of protons and neutrons in your particular question is 59, the answer to what has 27 protons and 32 neutrons is the particular isotope of cobalt labeled 59Co. This is cobalt's only stable isotope.
An ion of copper, Cu+2, has 27 electrons and a charge of +2. The copper atom has loaned out (or had borrowed from it) in a chemical reaction, those 2 electrons. An ion is formed any time the number of electrons an atom has does not equal the number of protons in its nucleus. The 2 electrons plus 27 electrons makes 29 electrons - just the number that are present in a neutral atom of copper.
The atomic masses of two isotopes of cobalt are 59 and 60. What is the number of protons in each?
26 is the atomic mass because the number of protons and neutrons together = atomic mass
Aluminium is the 13th element, with an atomic number (of protons in the nucleus) of 13 and a mass number of 27 (number or neutrons + protons).
The number of protons is equal to the number of electrons. Cobalt is the element with 27 protons. Cobalt is a d block metal.
Cobalt has 27 protons. The double of 27 is 52, and the atom with 52 protons is tellerium.
Cobalt: Its atomic number, which equals the number of protons in its nucleus, is 27.
This would be a rather large electron configuration with somehwere around 27 valence electrons.... its kind of like playing with fire stating these facts though since this elements has been discovered but not fully confirmed.

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.
Protons and neutrons have roughly the same mass, regardless of the element. Proton mass: 1.67262171(29)×10−27 kg Neutron mass: 1.67492729(28)×10−27 kg
