What element has the electron configuration 4s2 3d7?
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.
What is the electron configuration of the element with 27 protons?
The electron configuration of cobalt is [Ar]3d7.4s2.
In the elements in the middle section of the periodic table which orbital are the electrons being added?
the outer shell electrons of the transition elements (middle section) go into the 'd' orbital e.g. Cobalt (Co) 1s2 2s2 2p6 3s2 3p6 4s2 3d7 The 4s orbitals get filled up before the 3d orbitals because it takes less energy to fill the 4s orbital
What is the period block and group of the element with the electron configuration Ar 3d74s2?
the element belongs to 4th period, 9th group, it is a d block element. the element is cobalt
What is the abbreviated electron configuration of cobalt?
The abbreviated electron configuration of cobalt is [Ar] 3d7 4s2.
What is the configuration for co?

What is the electron configuration of Colbat?
Cobalt has an electron configuration of 1S2 2S2 2P6 3S2 3P6 4S2 3d7 or. [Ar] 4S2 3d7
What element has 27 protons in its orbital diagram?
The element with 27 protons is cobalt (Co). Its electron configuration is 1s2 2s2 2p6 3s2 3p6 4s2 3d7.

Write out electron configurations for N and Co?
Cobalt electron configuration is [Ar]3d7.4s2.Nitrogen electron configuration is [He]2s2.2p3.
What is complete electron configuration for an atom of cobalt?
The electronic configuration of cobalt is :1s2 2s2 2p6 3s2 3p6 3d7 4s2 This is so because cobalt has an atomic no of 27. So it will have 27 electrons. The 1st shell can accommodate a maximum of 2 electrons, the 2nd shell can accomodate 8. So that makes it 10, 17 to go. Now the 3s and 3p subshells get filled up with 2 and 6 electrons respectively, but after that instead of the 3d subshell, the 4s subshell gets filled up.(This is so because the 4s subshell has a lower energy level than 3d).So that makes it 20 electrons. The remaining 7 proceed into the 3d subshell to make a total of 27.
What is the noble gas configuration for Co?
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.
Electron configuration for the two plus cation of Co?
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.
What is the core notation for the electron configuration of a cobalt 2 ion?
The core notation for the electron configuration of a cobalt 2 ion is [Ar] 3d7. The [Ar] represents the electron configuration of the argon noble gas, which has the electron configuration 1s2 2s2 2p6 3s2 3p6. The 3d7 indicates that there are seven electrons in the 3d subshell of the cobalt ion.
What is the electron configuration of the element with 27 protons?
The electron configuration of cobalt is [Ar]3d7.4s2.
In the elements in the middle section of the periodic table which orbital are the electrons being added?
the outer shell electrons of the transition elements (middle section) go into the 'd' orbital e.g. Cobalt (Co) 1s2 2s2 2p6 3s2 3p6 4s2 3d7 The 4s orbitals get filled up before the 3d orbitals because it takes less energy to fill the 4s orbital
What is the total number of electrons in an atom of 27 Co?
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.
