Some elements form monatomic molecules because they have a stable electron configuration when they exist as single atoms. These elements have filled valence electron shells, making it energetically favorable for them to exist as single atoms rather than bonding with other atoms to form molecules.
Yes, it is acceptable to use the noble gas configuration to represent the electron configuration of some elements. This simplifies the process by labeling the core electrons as the nearest noble gas configuration and then adding the valence electrons for the specific element.
The electron configuration in the outer shell is the same for all of the elements in the same column. This results in some similar chemical properties between these elements in the same group (column).
Sodium Magnesium Aluminium Silicon Phosphorus Sulphur Chlorine All the above seven elements have same core-electron configuration as that of neon.
No, the electron configuration for an ion is not always the same as that of its nearest noble gas. When an atom loses or gains electrons to form an ion, its electron configuration changes. For example, a sodium ion (Na⁺) has the electron configuration of [Ne], which is the same as neon, but a chloride ion (Cl⁻) also has the same configuration as argon ([Ar]). Thus, while some ions can have configurations similar to noble gases, this is not universally true for all ions.
We can predict the electron configuration, some chemical and physical properties, the atomic weight, etc.

Some elements become ions by gaining or losing electrons to achieve a stable electron configuration. When an element gains electrons, it becomes a negative ion (anion), while losing electrons results in a positive ion (cation). This process allows the element to achieve a full outer electron shell and become more stable.

Noble gases are called inert gases because they are the least reactive elements due to their stable electron configuration. They have a full outer electron shell, making them highly stable and unlikely to form chemical bonds with other elements. This inertness gives them low reactivity under normal conditions.
Iodine accepts one electron to achieve noble gas configuration. Strontium loses two electrons to achieve noble gas configuration. Nitrogen accepts three electrons to achieve noble gas configuration. Krypton already has a noble gas configuration.
Metalloids typically have electron configurations that show characteristics of both metals and nonmetals. They often have an outer shell electron configuration that is intermediate between metals and nonmetals, with some similarities to both groups. For example, metalloids like silicon and germanium have electron configurations that show both metallic properties (conductivity) and nonmetallic properties (brittleness).
Some elements achieve stable electron configurations through the transfer of electrons, which occurs in ionic bonding. This process involves one element losing electrons (cation) and another element gaining electrons (anion) to reach a stable configuration. Ionic bonding typically occurs between metals and nonmetals with significant differences in electronegativity.
