Noble gases have completely filled orbitals. They generally have 8 valence electrons (helium has only 2) and obey octet rule (stable electronic configuration). Hence they are chemically inert (or do not react with other elements).
Chemical properties depend on electron configuration. By either gaining or losing electrons, an atom changes its electron configuration and therefore its chemical properties also change.The atoms of an element will react to achieve a noble-gas configuration. The atoms will either gain or lose electrons to achieve such a configuration.
False. Alkali metals lose one electron to form a stable electron configuration with a full outer shell of electrons, which is the stable electron configuration for these elements.
A duplet electron configuration is considered stable, as it corresponds to having two electrons in the outer energy level, which is the most stable configuration for elements in the first period. Elements like helium achieve a duplet electron configuration and are relatively stable due to their full outermost energy level.
When sodium (Na) bonds with chlorine (Cl), sodium donates one electron to chlorine. As a result, chlorine achieves a stable electron configuration resembling that of the nearest noble gas, argon. Chlorine ends up with a full outer shell containing eight electrons, giving it the electron configuration of (1s^2 2s^2 2p^6), which is characteristic of a stable, anionic form (Cl⁻).
Potassium can lose one electron from its outer shell to achieve a stable electron configuration similar to argon. Fluorine can gain one electron to fill its outer shell and attain a stable electron configuration like neon. In both cases, the atoms are trying to achieve a full valence shell and become stable like the nearest noble gas.

Na+ is the formula of the ion formed when sodium achieves a stable electron configuration.
What symbol would represent a chlorine ion that has ionized to have a stable electron configuration?
Although the formation of an octet is the most stable electron configuration, other electron configurations provide stability. These relatively stable electron arrangements are referred to a pseudo-noble gas configuration. Although the formation of an octet is the most stable electron configuration, other electron configurations provide stability. These relatively stable electron arrangements are referred to a pseudo-noble gas configuration.
The group of elements that have a stable electron configuration are the noble gases.
False. Alkali metals lose one electron to form a stable electron configuration with a full outer shell of electrons, which is the stable electron configuration for these elements.
Four: All of its valence electrons. If a silicon atom loses four electrons, it has the stable electron configuration of neon, while if the atom gains four electrons it has the stable electron configuration of argon. A silicon atom can also form a stable compound, as contrasted with a stable electron configuration for a single atom, by sharing four electrons with one or more other atoms.
The noble gas configuration for fermium (Fm) is [Rn] 5f12 7s2. It represents the electron configuration of fermium in a stable state, where it mimics the electron arrangement of the noble gas radon (Rn) to achieve a more stable configuration.
gaining one electron to achieve a full valence shell. This would result in the formation of a bromide ion (Br-), which has a stable electron configuration similar to that of a noble gas.
A duplet electron configuration is considered stable, as it corresponds to having two electrons in the outer energy level, which is the most stable configuration for elements in the first period. Elements like helium achieve a duplet electron configuration and are relatively stable due to their full outermost energy level.
The electron configuration of boron is 1s2 2s2 2p1. When boron becomes an ion, it typically loses its outer electron to achieve a stable electron configuration. Therefore, the electron configuration of a boron ion is typically 1s2 2s2.
A stable electron configuration for a chlorine ion can be achieved by gaining one electron. This would give the chlorine ion a full outer shell of electrons. The symbol for a stable chlorine ion with an extra electron would be Cl-.
