Which element has the electron configuration 1s2 2s2 2p6 3s2 3p6 4s2 3d2?

Which element has the electron configuration 1s2 2s2 2p6 3s2 3p6 4s2 3d2?

1 Answer. Stefan V. If you are referring to a neutral atom, then Vanadium (V) has that particular electron configuration. This means that the atom you’re looking for has an atomic mass of 23, which corresponds to the atomic mass of Vanadium, a transition metal located in the fourth row, group 5 of the periodic table.

What element is Ar 4s2 3d10 4p4?

When you look it up, you should locate selenium and find that it has atomic number 34 .

What is the ground state electron configuration of potassium?

Ground state electron configuration of potassium (K) is 1s 2 2s 2 2p 6 3s 2 3p 6 4s 1. The valency of the element is determined by electron configuration in the excited state. This electron configuration shows that the last shell of the potassium atom has an unpaired electron (4s 1 ). So the valency of potassium is 1.

How many electrons are in the 2s orbital of potassium?

Since 1s can only hold two electrons the next 2 electrons for Potassium go in the 2s orbital. The next six electrons will go in the 2p orbital. The p orbital can hold up to six electrons. We’ll put six in the 2p orbital and then put the next two electrons in the 3s.

Is potassium a cation or an ionic compound?

That is, potassium is a cation element. The electron configuration of potassium ion (K +) is 1s 2 2s 2 2p 6 3s 2 3p 6. The electron configuration of potassium-ion shows that potassium ions have three shells and the last shell has eight electrons.

What is the atomic number of potassium (K) 19?

The atomic number is the number of electrons in that element. The atomic number of potassium (K) is 19. That is, the number of electrons in potassium is nineteen. Therefore, the potassium atom will have two electrons in the first shell, eight in the 2nd orbit.
