While filling electrons in Berrylium, the 2nd electron will occupy which orbit?
1st Orbit
2nd Orbit
3rd Orbit
4th Orbit
Beryllium has the atomic number - 4 and electronic configuration as 2,2
So, while filling electron 2nd electron will occupy space in 1st Orbit.
While filling the electron in a Carbon atom, which orbit will be occupied by the last electron getting filled?
Statement 1: Hydrogen just needs 2 electrons to fill its outermost orbit.
Statement 2: The first orbit can occupy only 2 electrons.
Statement 1: Hydrogen atom just needs 1 extra electron to fill its outer-most orbit.
