It really isn't that hard, just a little long and frustrating.
You can determine the number of valence electrons from the group number of a representative element. For example, elements in group 1 have 1 valence electron, while elements in group 14 have 4 valence electrons. Additionally, elements in the same group tend to have similar chemical properties due to their shared electron configurations.
The electron in the highest occupied energy level is known as the valence electron. These electrons are involved in the formation of chemical bonds and determine the element's chemical properties.
a filled highest occupied principal energy level
the elections with the highest energy are in an f sub level. your welcome :))
They relate to the sub orbital type, or the highest energy orbitals that are occupied in a given element that falls under the subsequent block of the periodic table. Plato: Its not D. none of the above
Elements in a group have the same number of valence electrons, giving them similar electron configurations. The electron configurations differ by the number of filled inner shells, leading to a trend in chemical reactivity within the group. The periodic table is organized based on these similarities in electron configurations within groups.

The valence electron shell of noble gases is full.

This description fits elements in the lanthanide and actinide series of the periodic table. These elements have their highest occupied s sublevel and a nearby f sublevel containing electrons due to the electron configurations in their atoms.
The electron in the highest occupied energy level is known as the valence electron. These electrons are involved in the formation of chemical bonds and determine the element's chemical properties.
Neutral atoms with s or p electron configurations in the highest energy level are classified as main group elements or representative elements. These elements typically exhibit a wide range of chemical properties due to their varying numbers of valence electrons.

The Bohr model of the atom helped explain the arrangement of electrons in discrete energy levels or shells around the nucleus. This concept of electron shells provided a basis for understanding the organization of the elements on the periodic table, where elements are arranged by increasing atomic number and by recurring chemical properties based on their electron configurations.
