Oganesson is present in period 7 of the modern periodic table. All the shells are completely filled and it is placed in group 18. Let us see the electronic configuration of Oganesson.

Its Atomic Number is 118, its Mass number is 294, and Og is its element symbol. It belongs to the P- block. It has Fcc centered cubic structure. It has no stable isotopes. It has 176 neutrons. Its key isotope is 294Og, and its Electron affinity is 5.43 KJ mol-1.

Let us see some facts about Oganesson’s electronic configuration and its orbital diagram.

## How to write Oganesson electron configuration?

Certain rules write the electronic configuration; rules are the Aufbau principle, Hund’s rule, and Pauli’s exclusion principle.

The Aufbau principle, Hund’s rule, and Pauli’s exclusion principle decide how the electrons are filled in an atomic orbital.

### Step-1 writing the energy order of the orbitals, we use the Aufbau principle.

It states that electrons will occupy orbitals having lower energy before occupying higher energy orbitals. According to this principle, electrons are filled in the following order – 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p.

• It states that electrons will occupy orbitals having lower energy before occupying higher energy orbitals. According to this principle, electrons are filled in the following order – 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p.
• Step-2 Using Paulis exclusion principle to fill up electrons. It tells us that no two electrons in the same atom can have the same value of all four quantum numbers.
• Step -3 Arrangement of orbitals by Hund’s rule. The rule states that electrons must singly occupy all the orbitals of a given sublevel before pairing begins.

Oganesson contains 118 electrons; we can write the electronic configuration using the above information.

1s orbital has the minimum energy; therefore, it is filled first with two electrons which is its maximum capacity.

From the Aufbau principle, we know that 2s orbital is higher in energy than 1s orbital. Thus 2s orbital is filled with a maximum capacity of two electrons after the 1s orbital.

• After that, the 2p orbital is full. It can hold a maximal of six electrons.
• After that, the 3s orbital is full. It can hold a maximal of two electrons.
• After that, the 3p orbital is full. It can hold a maximal of six electrons.
• After that, the 4s orbital is full. It can hold a maximal of two electrons.
• The third orbital is then full. It can hold a maximum of ten electrons.
• After that, the 4p orbital is full. It can hold a maximal of six electrons.
• After that, the 5s orbital is full. It can hold a maximal of two electrons.
• After that, the 4d orbital is full. It can hold a maximum of ten electrons.
• After that, the 5p orbital is full. It can hold up to six electrons, so the 6s orbital is full. It can hold a maximal of two electrons.
• After that, the 4f orbital is full. It can hold fourteen electrons at once.
• After that, the 5d orbital is full. It can hold a maximal of ten electrons.
• After that, the 6p orbital is full. It can hold a maximal of six electrons.
• The 7s orbital is then full. It can hold a maximal of two electrons.
• After that, the 5f orbital is full. It can hold fourteen electrons at once.
• After that, the 6d orbital is full. It can hold a maximum of ten electrons.
