Which Element Forms A 3+ Ion That Has The Electron Configuration KR 4d 6?

What does kr mean in electron configuration?

Kr is the symbol for krypton, which is a noble gas.

Its atomic number is 36 and it is located in the fourth row on the periodic table.

Noble gases get their name because their outer electron shells are filled..

What element has an electron configuration of Kr 5s2?

antimony atomSo, for an antimony atom, the noble gas configuration would be [Kr] 5s2 4d10 5p3.

Which element forms a 3 3 ion that has the electron configuration KR 4d6 KR 4d6?

Rhodium Rh[ Kr ] 4d six ion has 42 electrons . As it is a 3+ ion , the parent atom would have forty-five electrons . This would make it Rhodium Rh .

Is a metal that forms a 3+ ion?

As an example, iron commonly forms two different ions. It can sometimes lose two electrons to form the Fe2+ ion, while at other times it loses three electrons to form the Fe3+ ion. Tin and lead, though members of the p block rather than the d block, also are capable of forming multiple ions.

What element is 1s2 2s2 2p6 3s2 3p6 4s2 3d6?

ironThus, following the rules on how to fill the orbitals, the electronic configuration of iron (for example) is 1s2 2s2 2p6 3s2 3p6 4s2 3d6 , and it is abbreviated form [Ar] 4s2 3d6.

Which element has the ground state electron configuration 1s22s22p63s2?

element Silicon2 Answers. BRIAN M. The electron configuration 1s22s22p63s23p2 is the element Silicon.

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 element forms an ion with an electronic configuration of KR and a charge?

Answer : The symbol of the element is Selenium (Se).

Which ion has the same electron configuration?

Atoms and ions that have the same electron configuration are called isoelectronic. Common ions of representative elements are isoelectronic with a noble gas. When forming ions, transition metals lose their valence s-sublevel electrons before they lose their d-sublevel electrons.
