If the first energy level is complete with two electrons then what has two elements?

If the first energy level is complete with two electrons, then the elements hydrogen and helium have two elements in their electron configuration. Hydrogen has one electron in its first energy level, while helium has two electrons filling its first energy level.


What is the electron shell diagram for helium?

Helium has one energy shell with only 2 electrons in it.


What element has one main energy level?

Helium has two electrons which completely fills the first principal quantum level.


What is the first energy level in helium called?

The first energy level in the quantum (current) theory of the atom is the 1s electron orbital, which can hold two electrons.The following energy levels go like this:1s22s22p63s23p64s24p63d105s25p64d106s2...And so on. (The first number being the energy level, the letter being the shape of the electron orbital, and the superscript being the number of electrons the orbital can hold.)


What is the first energy level of an electron?

The K shell's 1s orbital is te first energy level of an electron.


Which noble gas has only two energy levels?

Helium is the noble gas that has only two energy levels in its electron configuration. Its electron configuration is 1s2, which means it has two electrons in the first and only energy level.


The first element with an electron in the second energy level?

The first element with an electron in the second energy level is lithium. Lithium has three electrons, with two in the first energy level and one in the second energy level.


Why does Lewis diagram of helium differ from that of argon?

The Lewis diagram of helium shows two electrons paired in the first energy level, while argon shows two electrons paired in the first energy level and eight electrons paired in the second energy level. This difference is due to the atomic number and electron configuration of each element: helium has 2 electrons in total, while argon has 18 electrons in total.


What information does the first quantum number of an electron give?

The energy level the electron is in


What is the highest occupied energy level in He?

It is 2p. Because the electron configuration for oxygen is 1s2 2s2 2p4, therefore 2p being the greatest or highest energy level


What is the number for electrons on hydrogen's first energy level?

Hydrogen's electron configuration is 1s1. It has only one electron. It is located in the first energy level.


Does an atom of helium have eight electrons in its outer energy level?

the largest number of electrons an atom of helium can have is 2, because it is in the first period, which means it can only have one energy level, which has a maximum capacity of two electrons
