Argon, being one of the noble gases, has a completely filled outer electron shell and thus has zero valency.
What else can I help you with?
When a calcium atom loses its valence electrons the ion formed has an electron configuration that is the same as an atom of?
Argon. Calcium has the electron configuration 1s2 2s2 2p6 3s2 3p6 4s2, and when it loses its valence electrons (the outermost 4s2 electrons) it has a configuration identical to argon. If you don't know about sublevels, then disregard that. Calcium has a configuration of 2-8-8-2, and when it loses its 2 valence electrons, it has a configuration identical to argon in the ground state. Hope that cleared it up
What is the valence electron configuration of argon?
Argon, being one of the noble gases, has a completely filled outer electron shell and thus has zero valency.
Does KR and AR have the same valence electron configuration?
Krypton and argon both have 8 valence electrons. This is true of all noble gases except helium, which has only 2 valence electrons.
Would aluminum gain or lose electrons to becom like argon?
Aluminum would lose 3 electrons to become like argon. Argon has a full valence shell with 8 electrons, so aluminum, with 3 valence electrons, would need to lose these electrons to achieve a full valence shell configuration similar to argon.
How many valence electrons do argon has?
Argon is a noble gas. All noble gasses have 8 valence electrons. Thus argon has 8 valence electrons as well.
How many valence electrons must calcium lose or gain to have 8 valence electrons?
It loses 2 electrons to obtain the argon configuration of 8 valence electrons.
What is the valence in argon?
Argon has a valence of 0 because it is a noble gas and already has a full outer shell of electrons.
Why argon octet?
Argon, as a noble gas, is chemically stable because it has a full valence shell of electrons (8 electrons). This full valence shell gives argon the same electron configuration as the nearest noble gas, neon, which is very stable. Because of this stability, argon tends not to react with other elements to form compounds.
How many bonds does argon have?
Argon is a noble gas and therefore does not typically form bonds with other elements, as its electron configuration is stable with a full valence shell. It exists as single atoms in its natural state.
How many valence electrons are there argon?
8 valence electrons- 1s22s2p63s2p6
Which sub levels contain valence electrons in an atom of argon?
In an atom of argon (atomic number 18), the valence electrons are found in the 3s and 3p sublevels. Specifically, argon has a complete outer shell with the electron configuration of 1s² 2s² 2p⁶ 3s² 3p⁶. Therefore, the valence electrons are the two electrons in the 3s sublevel and the six electrons in the 3p sublevel, totaling eight valence electrons.
Why does argon not react?
because it is a noble gas and already has its eight valence electrons. That makes it highly unlikely to react.
