helium
Zinc has this electron configuration.
The element with this electron configuration is tin (Sn), which has an atomic number of 50. The electron configuration provided corresponds to the electron distribution in its various electron orbitals.
The symbol of the first element to have an electron in the 4d sublevel in its ground state is Yttrium, symbolized as Y, with the electron configuration [Kr] 4d^1 5s^2.
It loses 2 electrons and becomes a +2 ion.
The first shell only hold 2 electrons, so this element has 1 electron in its first level. Hydrogen
This chemical element is calcium (Ca).
The element with this electron distribution is sulfur (S). The electron configuration 1s^2 2s^2 2p^6 3s^2 3p^4 corresponds to the atomic number 16, which is sulfur.
