An element is a pure substance that contains two or more electrons. There are many different elements known to man.
7 Helium contains two electrons in all naturally occurring states.
The correct electron configuration for an element with 5 electrons, which is boron (B), is 1s² 2s² 2p¹. This indicates that the first energy level (1s) contains two electrons, the second energy level (2s) contains two electrons, and one electron is in the 2p subshell. Thus, the total adds up to five electrons.
Helium is the element in the noble geses family that does not have an octet. Helium is the element in the noble geses family that does not have an octet.
There are 2 electrons in level one of a helium atom.
