Electron configuration for He?
1s2 Or, He(2) i.e., Helium has only two electrons and it is a completely filled first shell making it the simplest noble gas.
What is the oribital notation of helium?
it's an up arrow and down arrow next to each other, beneath that it says 1s2.
Why does helium end in s² than p6?
helium has only 2 electrons and hence its configuration is 1s2

The solar system contains only the sun planets and satellites?
It also contains asteroids and comets, which technically are not satellites as they do not orbit a planet, but orbit the sun in the asteroid belt, the Kuyper belt, and the Oort cloud.
What three subatomic particles are found in the nucleus?
The nucleus of an atom contains only protons and neutrons. Electrons orbit the nucleus.
Is the electron configuration for a Si atom written as 2.8.8.4?
It is written as 1s2 2s2 2p6 3s2 3p2. The innermost electron "ring" contains 2 electrons, the next contains 8 and the last contains 4.
