Why does 4s orbital start filling while 3p orbital is empty?

The electrons fill in the lowest energy orbital that is available. Electrons in the 4s orbital have a lower energy level than electrons in the 3p orbital, so the 4s orbitals are filled with electrons first.


Why does the s orbital fill before the p orbital?

It has a lower energy level. All else being equal, electrons tend to go into the lowest energy orbital with space available.


When an atom absorbs enough energy electrons move to an orbital?

The electrons become excited and move to higher energy orbitals.


What is the electron configuration of an element?

The electron configuration of an element shows the number of electrons in their energy levels and orbitals. For example, the electron configuration of a neutral magnesium atom, Mg, with 12 electrons, is 1s22s22p63s2. This means that there are two electrons in the s orbital of the first energy level, two electrons in the s orbital and six electrons in the p orbital of the second energy level, and two electrons in the s orbital of the third energy level. The number in front of each letter represents the energy level, the letter represents the orbital, and the superscripts represent the number of electrons in the orbital.


Is valence electrons in the outer most orbital?

No. Valence electrons are the electrons in the outer most orbit (or energy level) and not in outer most orbital.


How many d electrons can there be in an energy level?

There can be 10 electrons in a D orbital


What is subshell or sub energy level?

The level of energy possessed by all electrons in one type of orbital


How many electrons are held in the second energy level?

A total number of 8 electrons. Two in the 2s orbital and six in the 2p orbital


Why do electrons enter the 4s orbital before entering the 3d orbital?

because its energy level is lower


What is energy sublevel?

The level of energy possessed by all electrons in one type of orbital


Must Electrons must fill the higher energy levels before they fill the lower energy levels?

No, according to Hund's rule the electrons fill the lowest orbital first and foremost and then go on to fill higher orbitals.


What do you call the regions of the atoms in which electrons move?

Energy levels or orbital
