The element is sulfur with 16 electrons. It gains two electrons to form sulfide ion which has 18 electrons as that of argon.
It is about Cf element. it is in the !8th group.
The element that forms a 2+ ion with the same electronic configuration as Ar is Calcium (Ca). When Calcium loses two electrons, it attains the same electronic configuration as argon by having a full outer shell of electrons.
No, chlorine (Cl) does not have a noble gas electronic configuration. It has the electron configuration [Ne]3s^2 3p^5, which is one electron away from achieving a stable, noble gas configuration like argon (Ar).
The noble gas that is isoelectronic with S2- is Argon. Both S2- and Argon have 18 electrons.
The element symbol for argon, Ar, is derived from the first two letters of the element's name.
Argon is the most unreactive in this series. Cheese is not an element; it is a mixture of compounds.
The element is Argon. Its configuration is 2 8 8.
The element is sulfur with 16 electrons. It gains two electrons to form sulfide ion which has 18 electrons as that of argon.
It is about Cf element. it is in the !8th group.
Ca
The innermost electron shell of argon, which is occupied first, contains a total of 2 electrons.
The abbreviated electron configuration for argon is [Ne] 3s^2 3p^6. The [Ne] represents the electron configuration of the noble gas neon, which has the same electron configuration as the inner electrons of argon.
Argon was first discovered in 1894 by scientists Sir William Ramsay and Lord Rayleigh. They identified it as a new element in a sample of atmospheric nitrogen.
The element described has more valence electrons than oxygen but fewer than neon, more protons than sodium but fewer than argon. This element is magnesium, which has 12 protons, 12 valence electrons (2 more than oxygen but 2 less than neon), and is situated between sodium and argon on the periodic table.
Calcium
The element with 10 electrons in its neutral state is neon (atomic number 10). When it forms an anion with a 2- charge, it gains 2 electrons to have a total of 12 electrons, taking on the electron configuration of the noble gas, argon.
