Question

Please select the word from the list that best fits the definition: The notation specific to the organization or arrangement of electrons within orbitals surrounding the nucleus of an atom.

A) Electron configuration
B) Energy levels

Answer 1

The term 'electron configuration' refers to the specific notation used for the arrangement of electrons in energy levels and orbitals of an atom, denoting the number of electrons in each orbital with a superscript. Orbitals, such as s and p, have distinct shapes and are used to predict where electrons are likely to be found within an atom.

Step-by-step explanation:

Electron configuration refers to the distribution of electrons in atomic orbitals. It is a crucial concept in understanding the organization of electrons within an atom. The notation describes the arrangement of electrons in various energy levels and sublevels around the nucleus. Energy levels, also known as electron shells, are the regions where electrons are likely to be found.

In the electron configuration notation, the main energy levels are represented by numbers (1, 2, 3, etc.), and sublevels are denoted by letters (s, p, d, f). For example, the electron configuration of hydrogen is 1s¹, indicating that it has one electron in the first energy level's s sublevel.

Understanding electron configuration is essential for predicting an element's chemical behavior, bonding tendencies, and its placement on the periodic table. The arrangement of electrons in orbitals is a key factor in determining the chemical properties of elements and their ability to form compounds.
