The element with that electron configuration has 4 electrons in the third level. There are 2 electrons in the 3s sublevel and 2 more electrons in the 3p sublevel. This means 4 valence electrons total. This element is silicon (Si, #14).
The principal energy level that contains electrons with the lowest energy is the first energy level (n=1). This level is closest to the nucleus and has the least amount of energy associated with its electrons.
Electrons in the outermost electron shell have the most energy in an atom. The energy of an electron increases as it moves further away from the nucleus. Electrons in the innermost shell have the least energy, while electrons in the nucleus have the highest energy due to their proximity to the protons.
The principal quantum number for the highest energy electron in carbon would be 2. It is easy to spot this, since carbon exists in row 2 of the period table. The row in which an element resides always shows the highest value of n, or the principal quantum number, that an electron can reside in.

Sodium has one electron in its outermost principal energy level, also known as the valence shell.
The electron configuration of sodium is [Ne]3s1.
The principal energy level that contains electrons with the lowest energy is the first energy level (n=1). This level is closest to the nucleus and has the least amount of energy associated with its electrons.
Valence electrons are found in the outermost energy level of an atom, also known as the highest principal energy level. These are the electrons involved in chemical bonding and determining the reactivity of an element.
An element's period is related to its electron configuration by indicating the energy level of its outermost electrons. Each period corresponds to a new energy level, with elements in the same period having electrons in the same principal energy level. Electron configuration describes the arrangement of electrons in these energy levels, with each period accommodating a specific number of electron shells.
Electrons in the outermost principal energy level are called valence electrons.
The electron configuration of sodium is 1s2 2s2 2p6 3s1. It has three principal energy levels. It has only one valence electron.
Electrons in the outermost electron shell have the most energy in an atom. The energy of an electron increases as it moves further away from the nucleus. Electrons in the innermost shell have the least energy, while electrons in the nucleus have the highest energy due to their proximity to the protons.
The principal quantum number, denoted by ( n ), describes the main energy level of an electron in an atom. It indicates the average distance of the electron from the nucleus and the energy level of the electron. An increase in the principal quantum number corresponds to the electron being in a higher energy level and farther away from the nucleus.
The principal quantum number for the highest energy electron in carbon would be 2. It is easy to spot this, since carbon exists in row 2 of the period table. The row in which an element resides always shows the highest value of n, or the principal quantum number, that an electron can reside in.
The chloride ion (Cl-) has 8 electrons on the outermost energy level.
