• It is located in the 7th period of the periodic table.
2. Determine the group/family:
• Flerovium is in Group 14 of the periodic table, which is the Carbon family.
3. Determine the electronic configuration:
• The electronic configuration of an element is determined by filling electrons into the atomic orbitals following the Aufbau principle, Hund's rule, and the Pauli exclusion principle.
• For
Z=114,
the electrons fill up to the 7p orbital.
4. Write the electronic configuration:
• The electronic configuration of Flerovium is
[Rn]5f146d107s27p2.
5. Match with the given options:
• Option 1: Carbon family,
[Rn]5f146d107s27p2
• Option 2: Oxygen family,
[Rn]5f146d107s27p4
• Option 3: Nitrogen family,
[Rn]5f146d107s27p6
• Option 4: Halogen family,
[Rn]5f146d107s27p5
The correct option is Option 1, which corresponds to the Carbon family and the electronic configuration
[Rn]5f146d107s27p2.
Therefore, the element
Z=114
belongs to the Carbon family with the electronic configuration
