Which statement best describes how electrons till orbitals in the penodic table?
Electrons fill orbitals in order of their increasing energy from left to right
o Electrons fill orbitals in order of their increasing energy from right to left
Elements fill orbitals in order of increasing energy from top to bottom in each group
Elements fill orbitals in order of increasing energy from bottom to top in each group.

Answer :

Answer:

Electrons fill orbitals in order of increasing orbital energy

Explanation:

Apex

The periodic table consists of elements placed in increasing order of atomic numbers. In the table, electrons fill orbitals in increasing orbital energy. Thus, option A is correct.

What is the Aufbau principle?

The Aufbau principle states the filling of the orbitals and subshells of the atom with the electrons based on the energy levels. The electron occupies the lowest energy level.

The filling of the electron proceeds with an increase in the energy levels or the orbitals that in a periodic table increases from left to right across a horizontal row.

In a period, the number of the subshell or orbitals increases with an increase in the atomic number. The electron fills the higher energy levels after they have completely occupied the low energy levels.

Therefore, in option A. the electrons fill from an increasing order of energy levels.
