What else can I help you with?
How many valence electron does Ca lose or gain to attain noble-gas electron configuration?
Calcium loses two electrons to obtain a noble-gas electron configuration.
What noble gas has the same electron configuration as silicon?
Silicon has 4 valence electrons. No noble gases will have 4 valence electrons.
How many valance electrons are there in Fr plus?
Fr is in the 1st period. It removes an electron to get noble gas configuration. Fr+ does not have valence electrons.Francium has 1 electron in its outermost energy level. It donates its outermost electron to stabilize its electron configuration. Francium(I) has no valence electrons.
What group attains Electron Configuration of noble gases by gaining one electron?
The group attains electron configuration of noble gases by gaining one electron is the halogens. They have seven valence electrons and need one more electron to complete their outer shell, resulting in a full valence shell like the noble gases.
Do noble gases have electron affinity?
The valence electron shell of noble gases id completely filled; as a consequence the affinity for electrons and the chemical reactivity are at an extremely low level.
Why are the noble gases non reactant?
Noble gases have atoms with the valence electron shell filled.
What is the valence electron of argon?
Valence electrons are the outer layer of electrons, the part that reacts. Argon is a noble gas, so it has a full valence electron level. It has eight valence electrons.
How many electrons does cesium have to give up to achieve a noble gas electron configuration?
Losing an electron cesium has a noble gas configuration.
What element has a complete valence electron shell?
An element with a complete valence electron shell is a noble gas. Noble gases have a full outer electron shell, making them stable and non-reactive. Examples include helium, neon, and argon.
How many valence electron does Ca lose or gain to attain noble-gas electron configuration?
Calcium loses two electrons to obtain a noble-gas electron configuration.
Why does helium belongs to noble gases where infact it has 2 valence electron?
Because helium has completely filled valence orbitals similar to other noble gases.
How many electrons do halogens have to lose or gain to achieve a stable noble gas electron configuration?
They have to gain 1 electron. Halogens have 7 electrons in their valence shell and noble gasses have 8.
What noble gas has the same electron configuration as silicon?
Silicon has 4 valence electrons. No noble gases will have 4 valence electrons.
How many valance electrons are there in Fr plus?
Fr is in the 1st period. It removes an electron to get noble gas configuration. Fr+ does not have valence electrons.Francium has 1 electron in its outermost energy level. It donates its outermost electron to stabilize its electron configuration. Francium(I) has no valence electrons.
What group attains Electron Configuration of noble gases by gaining one electron?
The group attains electron configuration of noble gases by gaining one electron is the halogens. They have seven valence electrons and need one more electron to complete their outer shell, resulting in a full valence shell like the noble gases.
What is true of electron configurations of the noble gases?
They all have a full set of valence electrons.
Do noble gases have electron affinity?
The valence electron shell of noble gases id completely filled; as a consequence the affinity for electrons and the chemical reactivity are at an extremely low level.
