Yes it is. Argon (atomic number 18) is the noble gas that is nearest to calcium (atomic number 20)
Argon (Ar) is the nearest noble gas to potassium.
The noble gas core notation for Calcium is [Ar]4s2. This notation represents the electron configuration of Calcium by using the nearest noble gas (Argon) as a reference.
argon (atomic number 18) is the closest to calcium (atomic number 20)
Argon is closest, as Calcium is number 20, and Argon is number 18.
No, calcium is not a noble gas. It is a metallic element in group 2 of the periodic table. Noble gases are a group of elements that are typically non-reactive due to their full valence electron shells, while calcium is reactive and forms ions in chemical reactions.
The noble gas nearest to Phosphorus (P) is Argon (Ar).
Calcium will lose two electrons to gain the noble gas configuration of Argon.
Calcium (Ca) has 20 electrons in its neutral state. To attain a noble gas electron configuration (like argon), calcium would need to lose 2 electrons to have the same electron configuration as argon, as argon has 18 electrons.
Argon is a noble gas
No noble gas is isoelectronic with the element chlorine. But argon is isoelectronic with the chloride ion.
No, calcium and argon cannot form a chemical bond with each other because argon is a noble gas and does not typically form chemical bonds. Calcium is a reactive metal that tends to form ionic bonds with nonmetals, but it does not form bonds with noble gases like argon.
A calcium atom must lose 2 electrons to achieve a noble gas structure, as it will then have the same electron configuration as argon, a noble gas. This loss of electrons allows the calcium atom to have a full outermost electron shell, giving it greater stability.
