A stable electron configuration refers to an atom in which the outer electron shell is full. Outermost electron shells hold a maximum of 2, 8, 8, 18,...(etc.) electrons. With an outer shell of 2 electrons, the Periodic Table shows that helium has a stable electron configuration. The next stable configuration of an element has 10 (2 + 8) electrons. This is neon. Neon is followed by argon, with 18 (2 + 8 + 8) electrons. Krypton, with 36 (2 + 8 + 8 + 18) electrons is next. The remaining stable configurations follow a similar pattern, based on the maximum number of electrons able to fit into the outermost ring. These elements are extremely stable and rarely react with other elements. They are referred to as the noble gases or inert elements. Atoms of other elements may bond with each other or different elements to form molecules having full outermost shells of electrons.

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.
The hydride ion (H-) is more stable than the hydrogen atom (H•) because the extra electron in the hydride ion helps to stabilize the negative charge through electron-electron repulsion. Additionally, the hydride ion benefits from a full electron octet, making it more stable compared to the hydrogen atom, which has an unpaired electron.
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.
Halogens in group 7 have high electron affinities because they only need to gain one electron to achieve a stable octet electron configuration, which is energetically favorable. This makes them highly reactive in forming stable compounds with metals that can donate an electron to satisfy their electron needs.
When chlorine gains an electron, it achieves a complete octet by filling its outermost valence shell with 8 electrons, which is the stable configuration of a noble gas. This helps it achieve a more stable electron configuration and become chemically stable.
The group of elements that have a stable electron configuration are the noble gases.
The ion formed when sodium achieves a stable electron configuration is Na+ (sodium ion). Sodium (Na) loses one electron to achieve a stable electron configuration similar to that of neon.
its not stable because last orbit need to loose electron to be stable
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.
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 process of removing an electron from a stable nucleus is called electron capture. In this process, an electron is absorbed by a proton in the nucleus, converting the proton into a neutron and releasing a neutrino. This results in a more stable arrangement of particles in the nucleus.
The symbol for a chlorine ion that has gained one electron to achieve a stable electron configuration would be Cl-.
No, sodium's outer shell is not stable because it only has one electron in its outer shell. Sodium will readily react with other elements to achieve a stable electron configuration by losing this electron.
For sodium to become stable, it must lose one electron to achieve a full outer electron shell. This typically occurs through the formation of an ionic bond with another atom that can accept this extra electron, such as chlorine. Once sodium loses its electron and forms a stable bond, it becomes a stable compound.
Lithium bonds due to its tendency to lose an electron and achieve a stable electron configuration. By losing this electron, lithium can attain a full outer energy level, making it more stable and forming bonds with other elements to satisfy its electron needs.
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-.
The hydride ion (H-) is more stable than the hydrogen atom (H•) because the extra electron in the hydride ion helps to stabilize the negative charge through electron-electron repulsion.
