First, we need to add up the number of electrons in the configuration 1s2 2s2 2p6 3s2 3p6 4s2 3d10. Doing so gives a result of 30. A neutral element having 30 electrons will also have 30 protons. Checking the Periodic Table, we see that zinc is the element with 30 protons.
The electron configuration of cobalt is [Ar]3d7.4s2.
The electron configuration of cobalt is Ar 3d7 4s2.
The abbreviated electron configuration of cobalt is [Ar] 3d7 4s2.
The electron configuration 1s2 2s2 2p6 3s2 3p6 4s2 3d7 represents the element manganese (Mn), which has an atomic number of 25.
The ground-state electron configuration of a neutral cobalt atom is [Ar] 3d7 4s2. This means that cobalt has two electrons in the 4s orbital and seven electrons in the 3d orbital.
The electron configuration of cobalt is [Ar]3d7.4s2.
Cobalt has an electron configuration of 1S2 2S2 2P6 3S2 3P6 4S2 3d7 or. [Ar] 4S2 3d7
The noble gas configuration for cobalt (Co) is [Ar] 3d7 4s2, where [Ar] represents the electron configuration of argon. This notation indicates that cobalt has the same electron configuration as argon, with an additional 3d7 4s2 electron configuration specific to cobalt.
The electron configuration of cobalt is Ar 3d7 4s2.
The abbreviated electron configuration of cobalt is [Ar] 3d7 4s2.
The electron configuration 1s2 2s2 2p6 3s2 3p6 4s2 3d7 represents the element manganese (Mn), which has an atomic number of 25.
[Ar] 4s2 3d7 or 2, 8, 15, 2
The element with 27 protons is cobalt (Co). Its electron configuration is 1s2 2s2 2p6 3s2 3p6 4s2 3d7.
The electron configuration for the +2 cation of cobalt (Co) is [Ar] 3d7. This is because cobalt has an atomic number of 27, which means its neutral configuration is 1s2 2s2 2p6 3s2 3p6 4s2 3d7. When it forms a +2 cation, it loses two electrons from its 4s subshell, resulting in the configuration [Ar] 3d7.
The ground-state electron configuration of a neutral cobalt atom is [Ar] 3d7 4s2. This means that cobalt has two electrons in the 4s orbital and seven electrons in the 3d orbital.
Co2+ has 25 electrons with the configuration: [Ar] 4s2 3d5 no its [Ar]3d^7
the element belongs to 4th period, 9th group, it is a d block element. the element is cobalt
