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.


What states that an electron occupies the lowest energy orbital that can receive it?

The principle that states an electron occupies the lowest energy orbital available is known as the Aufbau principle. According to this principle, electrons fill atomic orbitals in order of increasing energy levels, starting from the lowest energy level. This process continues until all the electrons are placed in the available orbitals, ensuring that the most stable electron configuration is achieved.


Why are the valence electrons of calcium in the 4s orbital not the 3d orbital?

Valence electrons occupy higher energy levels first before moving to lower energy levels, according to the aufbau principle. In calcium, the 4s orbital has lower energy than the 3d orbital, so valence electrons fill the 4s orbital first before the 3d orbital.


What is the highest occupied energy level in Beryllium?

The highest occupied energy level in Beryllium is the 2s orbital. Beryllium has 4 electrons, with 2 electrons in the 1s orbital and 2 electrons in the 2s orbital.


How many electrons does the first energy level lf an atom have?

The first energy level of an atom can hold a maximum of 2 electrons. This is due to the arrangement of electrons in orbitals, where the first energy level contains only the 1s orbital. According to the Pauli exclusion principle, each orbital can hold a maximum of 2 electrons with opposite spins.


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.


How many electrons can the 3rd energy level have?

it can be a logical amount of info but there are 3 indefinatlly


Is valence electrons in the outer most orbital?

Yes, valence electrons are the electrons in the outermost energy level or orbital of an atom. These electrons are involved in determining the chemical properties of an element and its ability to bond with other atoms.


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

There can be 10 electrons in a D orbital


How do you find out how many electrons are in the higher energy level of nitrogen?

Nitrogen has 7 electrons in total. In its ground state, nitrogen has two electrons in the 1s orbital and five electrons in the 2p orbital. Therefore, there are 3 electrons in the higher energy level (2p orbital) of nitrogen.


How many electrons can be held in the fourth orbital?

The fourth orbital, which is the 4d orbital, can hold up to 10 electrons. This orbital has a higher energy level than the 3d orbital and can accommodate more electrons. Each orbital can hold a maximum of 2 electrons per subshell (s, p, d, f).
