1 Answer. Helium, #"He"#, has an atomic number equal to #2#, which means that it has #2# protons in its nucleus. A neutral helium atom will thus have #2# electrons surrounding its nucleus. This means that the electron configuration for helium has to account for only #2# electrons. Both of these electrons are located on the first energy level ...
1 Answer. Just as simple as [H e]! Helium's electron configuration is [1s2]. But, helium is in the last row of the periodic table, which are noble gases. So, helium's noble gas configuration will be. [H e]. Just as simple as [He]! Helium's electron configuration is [1s^2].
1s^2 Helium has an atomic number of two which means it has 2 protons. A neutral He atom will also have 2 electrons. Here is a review of determining the number of subatomic particles in an atom. In its ground state, helium will have two electrons in the first energy level. These electrons are found in the 1s sublevel. Here is a video which discusses how to write electron configurations. Hope ...
Helium. For starters, your atom contains 2 electrons, so right from the start, you should be able to say that you're dealing with a helium atom, "He". You can say that because a neutral atom has equal numbers of protons inside the nucleus and of electrons surrounding the nucleus, regardless if the atom is in its ground state or not--keep in mind that this is true when dealing with atoms, not ...

Helium has 2 valence electrons, located in period 1, group 18 and in S-block. Therefore its electron configuration is, 1s2. I hope this helps. 1s2 Helium has 2 valence electrons, located in period 1, group 18 and in S-block.
The electron configuration of helium is 1s 2. An atom has two parts: a nucleus and the electron shells around it. An atom's weight is equal to the... See full answer below.
Electron Configurations are an organized means of documenting the placement of electrons based upon the energy levels and orbitals groupings of the periodic table. The electron configuration for the first 10 elements. H 1s1. He 1s2. Li 1s22s1. Be 1s22s2. B 1s22s22p1.
The electronic configuration of helium atom with atomic number 2 can be written as, 1s². The s orbital can accommodate only two electrons in them and helium having only two electrons gets completely filled. Helium being the inert gas has the most stable configuration. Therefore, 1s² is the electronic configuration of He.
To determine the electron configuration for helium, we need to consider its atomic number. Helium (He) has an atomic number of 2, meaning it has 2 electrons. Electrons fill orbitals in a specific order, known as the Aufbau principle. The order starts from the lowest energy level to the higher ones.
