What element completes the 4s sublevel?

The element that completes the 4s sublevel is calcium (Ca). It has the atomic number 20, which means it has 20 electrons. The electron configuration of calcium is (1s^2 2s^2 2p^6 3s^2 3p^6 4s^2), indicating that the 4s sublevel is filled after the 3p sublevel.


What chemical completes the 4s sublevel?

The 4s sublevel is completed by the element calcium, which has an atomic number of 20. In the electron configuration of calcium, the 4s sublevel is filled after the 3p sublevel, resulting in the configuration of 1s² 2s² 2p⁶ 3s² 3p⁶ 4s². Therefore, the completion of the 4s sublevel occurs when two electrons occupy it.


What element completes the 7s sublevel?

The element that completes the 7s sublevel is radium, with the electron configuration 7s2.


What element completes the 2p sublevel?

The 2p sublevel is completed with six electrons and is found in elements from carbon (C) onwards. The seventh element, nitrogen (N), is the element that completes the 2p sublevel.


What is the sublevel of al?

The sublevel of aluminum (Al), which has an atomic number of 13, is 3p. In its electron configuration, aluminum has the arrangement of electrons as 1s² 2s² 2p⁶ 3s² 3p¹, indicating that the outermost electrons are located in the 3p sublevel.


What element has 4 electrons in the 3p sublevel?

To find the element with a 3p4 valence configuration, look in period 3 and group XVI, and that is ...S, sulfur.


What is the chemical symbol that has 5 electrons in the 3p sublevel?

the total electron distribution in such an atom is 1s--2 2s--2 2p--6 3s--2 3p--5 so, total number of electrons comes out to be 17. so, the element is chlorine. symbol is Cl.
