2015年12月1日 · The **electron configuration **for oxygen is 1s2 2s2 2p4. In the electron configuration, the numbers represent the energy levels (1s, 2s, 2p), and the superscripts represent the number of electrons in each orbital.

2024年5月22日 · Those numbers denote electron orbitals, if my chemistry isn't too rusty that is Na (Sodium).

2024年10月23日 · The correct configuration for this element with 53 electrons would be 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s1.

2024年6月3日 · The group element is chlorine (Cl), which has an electron configuration of 1s2 2s2 2p6 3s2 3p5. Chlorine is located in Group 17 of the Periodic Table, also known as the halogens group.

2024年5月28日 · The correct electron configuration for a neutral atom with 28 electrons would be 1s2 2s2 2p6 3s2 3p6 4s2 3d8.

2024年6月20日 · Iodine. Add up all the superscript numbers to get 53, which is iodine's atomic number. Or, just look at the last term, 5p5. That's the element in period 5 that's one short of noble gas configuration.

2024年5月26日 · The full configuration of He 2s2 2p6 is 1s2 2s2 2p6. This configuration represents a neutral oxygen atom with its electrons distributed in the 1s, 2s, and 2p orbitals.

2024年2月26日 · 1s2, 2s2 2p6, 3s1: Containing 11 electrons, this configuration matches the neutral atom of sodium. 1s2, 2s2 2p6, 3s2 3p2: With a total of 14 electrons, it corresponds to a neutral silicon atom. 1s2, 2s2 2p6, 3s2 3p3: This configuration has 15 electrons and represents a neutral phosphorus atom, as indicated in the examples stated above.

2024年6月4日 · No, this electron configuration is not valid. The electron configuration should follow the Aufbau principle and Hund's rule. For the element with 3d5, it should be 1s2 2s2 2p6 3s2 3p6 4s1 3d5.

2020年11月7日 · The electron configuration of 1s2 2s2 2p6 3s1 belongs to an atom that has 11 electrons. Here's how we count them: The numbers 1s 2, 2s 2, 2p 6, and 3s 1 tell you the number of electrons in each orbital.
