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 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.
An electron in the second main energy level and the second sublevel is described by the symbols?
The electron in the second main energy level and second sublevel is described by the quantum numbers n=2 (main energy level) and l=1 (sublevel), which corresponds to the p orbital. The set of quantum numbers for this electron is 2p.
What is the sublevel of notation for Fe?
Iron (Fe) has an atomic number of 26. In terms of electron configuration, its sublevel notation is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d⁶. This indicates that iron has two electrons in the 4s sublevel and six electrons in the 3d sublevel, with the 3d sublevel being the highest energy level that is partially filled.
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 elements completes the 2s sublevel?
The 2s sublevel can hold a maximum of 2 electrons.
What is the maximum number of electrons that can go into sublevel 2s?
The maximum number of electrons in any s sublevel is 2, irrespective of what the principal quantum number, i.e., the number before the s in an electron configuration, may be.
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.
Which element has a single electron in the 2p sublevel?
The element that has a single electron in the 2p sublevel is boron. The electron configuration of Boron is 1s22s22p1.

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.
Why is it that all of the sub shells in a given shell have the same energy in the hydrogen atom whereas in a many-electron atom the sub shells in a given shell do not have the same energy?
The hydrogen atom only has one energy level (shell). The first energy level also contains only one sublevel, 1s sublevel (subshell), which can only hold two electrons. When you get to the second energy level in the second period on the periodic table, it has two sublevels, the 2s and the 2p sublevels. Both of the electrons in the 2s sublevel have the same energy. The 2p sublevel can hold 6 electrons. All of the electrons in the 2p sublevel have the same energy, which is higher than the energy in the 2s sublevel. So, as we move down the periods on the periodic table, we move from the first energy level to the seventh energy level. Each energy level contains specific numbers of sublevels, and all of the atoms within a particular sublevel have equal energy.
How many electron orbitals calcium have?
Zero. Calcium has two electrons in its 4s sublevel, and none in the 3d sublevel. The 3d sublevel doesn't start filling until after the 4s sublevel is filled.
Which element has one 2s electron?
Lithium
Number of electrons on an s sublevel in the outermost electron shell of the group IA?
one electron
How many 5s electrons are in Rb sublevel?
In the Rb atom, the electron configuration is [Kr]5s^1. This means there is 1 electron in the 5s sublevel of the Rb atom.
What is the difference between a 2s orbital and a 3s orbital?
The main difference between a 2s orbital and a 3s orbital is their energy levels. A 3s orbital is at a higher energy level than a 2s orbital. Additionally, the 3s orbital has a larger size and higher probability of finding an electron farther from the nucleus compared to a 2s orbital.
