What is the electron configuration of the ground state of the S2 ion sulfur Z 16 )?

S: 1s2 2s2 2p6 3s2 3p4 S2- : 1s2 2s2 2p6 3s2 3p6 Note: Replacement of 1s2 2s2 2p6 by [Ne] is acceptable.


Which of the following is the correct condensed electron configuration for titanium Z 22 )?

Let’s consider titanium (Z = 22). Its electron configuration is 1s2 2s2 2p6 3s2 3p6 4s2 3d2, which the (n + l) rule correctly predicts. If the electron configuration depended solely on the orbital energies, we would expect: 1s2 2s2 2p6 3s2 3p6 3d4 – with no electrons in the 4s orbital.


Who named potassium?

Potassium – the only element named after a cooking utensil. It was named in 1807 by Humphry Davy after the compound from which he isolated the metal, potash, or potassium hydroxide.


What does the number 84 in the name krypton 84 represent?

In the case of Krypton-84, this means that you have 84 nucleons, where 36 of these are protons, and the remaining 48 are neutrons. This becomes relevant in nuclear chemistry, where sometimes, you have to balance nuclear equations with respect to the mass numbers (nucleon numbers).


What element forms an ion with a +2 charge that has an electronic configuration of 1s22s22p6 or NE ])?

Oxygen has 6 valence electrons and it can gain two more to form a stable Noble Gas structure, hence it can form a 2+ ion.


What is Xe 4f1 5d1 6s2?

The ground state electronic configuration of Neutral Cerium atom is [Xe] 4f1 5d1 6s2. The portion of Cerium configuration that is equivalent to the noble gas of the preceding period, is abbreviated as [Xe]. For atoms with many electrons, this notation can become lengthy and so an abbreviated notation is used.
