Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Electron Configuration

Electron configuration describes the distribution of electrons in an atom's orbitals. It follows the Aufbau principle, which states that electrons fill orbitals starting from the lowest energy level to the highest. The configuration is typically represented using the notation of subshells (s, p, d, f) and the number of electrons in each subshell.

Periodic Table and Atomic Number

The periodic table organizes elements based on their atomic number, which is the number of protons in the nucleus. Each element has a unique atomic number, and for element Z = 116, this indicates it is the 116th element, known as livermorium. The position of an element in the periodic table helps predict its electron configuration based on its group and period.

Valence Electrons and Shells

Valence electrons are the outermost electrons of an atom and are crucial for determining chemical reactivity and bonding. The electron configuration reveals how many valence electrons an element has, which is influenced by its position in the periodic table. For heavy elements like Z = 116, understanding the filling of d and f orbitals is essential for predicting their chemical behavior.
