The family of 'noble' (= inert) gasses in group (column) 18 of the Periodic Table. Their valence shell is completely filled up with s2 and p6 electrons.
What else can I help you with?
Alkali metals lose an electron to form a stable octet. true or false?
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.
Is a duplet electron considered stable?
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.
Noble gases are very stable because their outermost electron shells contain the maximum number of electrons that those outermost shells can possess?
Yes, that's correct. Noble gases have full valence electron shells, meaning they have achieved the most stable electron configuration. This stable configuration makes them chemically inert and less likely to form chemical bonds with other elements.
What is the correct electron configuration of the ion formed by sulfur?
Sulfur typically forms a -2 ion (S²⁻) by gaining two electrons. The electron configuration for a neutral sulfur atom is 1s² 2s² 2p⁶ 3s² 3p⁴. For the S²⁻ ion, the electron configuration becomes 1s² 2s² 2p⁶ 3s² 3p⁶, which is the same as that of argon, indicating that it has achieved a stable noble gas configuration.
How does potassium and fluorine atoms change their electron configuration to obain a noble gas structure?
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.
What is the correct electron configuration for Cu?
The electron configuration of copper is: [Ar]4s13d10. It isn't 4s23d9 because Cu is able to obtain a more stable electron configuration when it takes an electron from the 4s and adds it to 3d. A half filled 4s and a completely filled 3d is more stable.
What is the formula of the ion formed when sodium achieves a stable electron configuration?
Na+ is the formula of the ion formed when sodium achieves a stable electron configuration.
What is a pseudo-noble gas?
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.
What symbol would represent a chlorine ion that has ionized to have a stable electron configuration?
What symbol would represent a chlorine ion that has ionized to have a stable electron configuration?
What group of elements have stable electron confoguration?
The group of elements that have a stable electron configuration are the noble gases.
Alkali metals lose an electron to form a stable octet. true or false?
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.
What is the noble gas configuration fermium?
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.
Is a duplet electron considered stable?
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.
What is the electron configuration of an ion of boron?
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.
Noble gases are very stable because their outermost electron shells contain the maximum number of electrons that those outermost shells can possess?
Yes, that's correct. Noble gases have full valence electron shells, meaning they have achieved the most stable electron configuration. This stable configuration makes them chemically inert and less likely to form chemical bonds with other elements.
What symbol represents a chlorine ion that has to have a stable electron configuration?
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-.
What is the formula of the most stable oxygen of francium?
The most stable oxidation state of francium is +1. Francium readily loses its single valence electron to attain a stable electron configuration similar to the noble gas configuration of cesium.
