Which of the following is the abbreviated electron configuration for cobalt III ion Co3 +?

The electron configuration of cobalt ion(Co3+) is 1s2 2s2 2p6 3s2 3p6 3d6.

What is the electron configuration of Co2+ ion?

Therefore, the configuration for Co2+ should be 1s2 2s2 2p6 3s2 3p6 4s0 3d7 and for Fe3+ should be 1s2 2s2 2p6 3s2 3p6 4s0 3d5.

Which is more stable Co2+ or Co3+?

We know Co3+ is more stable in complex compounds than Co2+ is in the same.

How do you write the electron configuration for cobalt?

The electronic configuration of cobalt is

  1. A. 1s2,2s2,2p6,3s2,3p6,3d1,4s2.
  2. C. 1s2,2s2,2p6,3s2,3p6,3d3,4s2.
  3. D. 1s2,2s2,2p6,3s2,3p6,3d5,4s2.

How many electrons does cobalt II ion have?

In this case, cobalt ion(Co2+) has a total of fifteen valence electrons. Again, the cobalt atom donates two electrons in 4s orbital and an electron in 3d orbital to convert cobalt ion(Co3+). Here, the electron configuration of cobalt ion(Co3+) is 1s2 2s2 2p6 3s2 3p6 3d6.

Why is cobalt III more stable than cobalt II?

This shows that Co(III) is quite strongly oxidising favouring formation of Co(II). It will even oxidise water. The +3 state can, however, be greatly stabilised by complexing with a ligand such as ammonia. Here we can see that the redox potential is much less +ve and now the stability of the Co(III) is greatly improved.

How many electrons are in the cobalt ion?

That is, the cobalt atom has a total of twenty-seven electrons. We know that the atomic number of cobalt is 27 and the atomic mass number is about 59(58.933u). Neutron (n) = 59 – 27 = 32.

Why is cobalt 3+ unstable?

Here, Co3+ is reduced to Co2+ and H2O is oxidized to O2. Since, E0 reaction is positive, Co3+ is unstable in aqueous medium.

Why does cobalt have a +3 charge?

Knowing that, we can figure out how many electrons cobalt has in its valence shell within the complex. In the periodic table, cobalt has nine valence electrons. However, if the overall complex has a charge of 3+, then the cobalt also had a charge of 3+. It has lost three electrons, so it only has six left.

What are the core electrons in Cobalts electron configuration?

Step-1: Determining the total number of electrons in cobalt. To know the number of electrons,you need to know the number of protons in cobalt.

  • Step-2: Need to do electron configuration of cobalt. Step 2 is very important.
  • Step-3: Determine the valence shell and calculate total electrons. The third step is to diagnose the valence shell.
  • What is complete electron configuration for an atom of cobalt?

    The electron configuration for Cobalt at ground state would simply be Co: [Ar] 4s23d7. The electron configuration of Cobalt will end in d block as Cobalt is an inner transition metal. Cobalt is in the 7th column of the d block and therefore has 7 d electrons d7.

    What is the valence electron configuration for cobalt?

    This configuration includes the argon core ([Ar]:1s^2 2s^2 2p^6 3s^2 3p^6). These electrons are core electrons because they are stable and do not take part in bonding. The remaining electrons are called valence because they do take part in bonding. Therefore, the configuration for the valence electrons for cobalt is 4s^2 3d^7.

    What is the electron affinity of cobalt?

    The electron affinity of cobalt is 63.7 kJ mol ‑1. The ionisation energies of cobalt are given below. Ionisation energies of cobalt. The following are ” Clementi-Raimondi ” effective nuclear charges, Zeff.
