How many energy levels would electrons of hydrogen and helium fill?

Electrons of hydrogen fill up to two energy levels, while electrons of helium fill up to a total of two energy levels as well. Helium has an additional energy level compared to hydrogen because it has 2 electrons, filling up both the first and second energy level.

What is the significance of the helium energy level diagram in understanding the electronic structure of helium?

The helium energy level diagram helps us understand how electrons are arranged in the helium atom. It shows the different energy levels that electrons can occupy, and how they are filled according to the rules of quantum mechanics. This diagram is important because it helps us predict the behavior of helium and other elements based on their electronic structure.


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.


What two atoms will have their outer energy level filled with two electrons?

Helium and neon will have their outer energy level filled with two electrons. Helium has 2 electrons in its only energy level, while neon has 8 electrons in its second energy level.


Why does helium have more emission lines than hydrogen?

Helium has more emission lines than hydrogen because it has more electrons and energy levels, leading to more possible transitions between these levels and the emission of different wavelengths of light.


How many electrons are in the third energy level of helium?

Oh, dude, helium only has two electrons total, so there can't be any in the third energy level. It's like trying to fit a square peg in a round hole - just not gonna happen. So, zero electrons in the third energy level of helium.
