Question: Which 1+ Ion Has The Ground State Electron Configuration KR 4d10?

What is the ground state electron configuration of the ion Cu +?

3d9Cu2+ has the ground-state electronic configuration [Ar]3d9..

Which is more stable cu2+ or Cu+?

Stability depends on the hydration energy (enthalpy) of the ions when they bond to the water molecules. The Cu2+ ion has a greater charge density than Cu+ ion and thus forms much stronger bonds releasing more energy.

Why is the electron configuration of Cu different?

In both examples, an electron moves from the 4s sublevel to produce a 1/2 full 3d (Cr) or completely filled 3d (Cu). This gives the atom greater stability so the change is favorable. It is important to note that this explanation is just looking at the examples of Cr and Cu.

Which if any is the ground state electron configuration for K +?

The ground state electron configuration of ground state gaseous neutral potassium is [Ar]. 4s1 and the term symbol is 2S1/2.

Which of the following is the correct electron configuration for cu2+?

So the electron configuration of Cu2+ is: 1s2 2s2 2p6 3s2 3p6 3d9.

Why does CU have a 2 charge?

Because the charge field density of the copper atom’s electron cloud moves a 4s into 3d. … Thus, copper certainly does have 2 valence electrons it can lose, giving it an oxidized state of 2+.

What is the correct electron configuration for potassium K?

[Ar] 4s¹Potassium/Electron configuration

What is the electron configuration of Br?

[Ar] 4s² 3d¹⁰ 4p⁵Bromine/Electron configuration

What element forms a 3+ ion with the electron configuration of KR 4d10?

FREE Expert Solution. Therefore, the element that forms the +3 ion that has the given electron configuration is Cobalt (Co).

What does the 2+ in cu2+ mean?

The old style system has different suffixes in their names. For example, Fe2+ is called the ferrous ion, and Fe3+ is called the ferric ion; Cu+ is the cuprous ion, and Cu2+ is the cupric ion. … Copper(II) means copper in the 2+ oxidation state.

Why does cu2+ have color?

Answer : Because do not contain any unpaired electron whereas contain one unpaired electron. Explanation: … As we know that the unpaired electrons present in the ion show color due to the transition of the electrons from ground state to the excited state.

Why is K+ more stable than k2+?

Atomic number of k = 19, … We see that, Pottasium(k) has 1 electron in it’s outermost shell, So k+ will have, 8 outermost electrons, According to Octet rule, K+ will be more stable !.

What is the name of cu2+?

cuprous ionThe old style system has different suffixes in their names. For example, Fe2+ is called the ferrous ion, and Fe3+ is called the ferric ion; Cu+ is the cuprous ion, and Cu2+ is the cupric ion. Notice that the ion with the lesser charge ends with –ous and the one with greater charges ends with –ic.

Which ion has the same electron configuration as Kr?

BrNotice how Br− has the same electron configuration as Kr. When this happens, the two are said to be isoelectronic. Write the electron configuration codes for the following atoms or ions using the noble gas electron configuration shortcut.
