No. Calcium gains the noble gas configuration (octet) if it loses two electrons and not one.
Calcium loses its two valence electrons to become Ca 2+ ion.
Sodium can become stable by losing 1 electron, forming a sodium ion with a 1+ charge, with the formula Na+. By losing its single valence electron, the resulting sodium ion achieves the noble gas configuration of neon, so that it has an octet (8) of valence electrons.
No, sodium is stable by losing 1 electron in order to achieve a full outer electron shell and become a positively charged ion called Na+.
Potassium forms a 1+ ion because it loses one electron to achieve a stable electron configuration like the nearest noble gas, argon. Calcium forms a 2+ ion by losing two electrons to attain a stable electron configuration like the nearest noble gas, argon.
Elements in group two become more stable as they all have complete electron shell.They do not have valence electrons and hence they are less reactive.Some of the elements of group 2 are Barium,Magnesium and Calcium
The oxidation number of calcium is +2, as it tends to lose two electrons to achieve a stable electron configuration. The oxidation number of chloride is -1, as it tends to gain one electron to achieve a stable electron configuration.
Elements tend to lose electrons and become positively charged ions if they have a few electrons more than a filled energy level. Elements like Lithium, Sodium, Potassium all have a tendency to lose one electron when bonding with other atoms.It is a matter of bonding most effectively.Beryllium, Magnesium, Calcium tend to lose 2 electrons when bonding.
Sodium. A sodium atom has one valence electron in its 3rd energy level. This is very unstable, so a sodium atom will lose that single valence electron to another atom (nonmetal), and the 2nd energy level will then have 8 valence electrons, which is stable. The positively charged sodium ion, Na+, will bond with a negatively charged ion; either a nonmetal or a polyatomic ion.
Sodium has 1 valence electron in its outer shell. By losing this electron, sodium achieves a full outer shell, which is more stable. This stable configuration is achieved by following the octet rule, where atoms tend to gain, lose, or share electrons to have 8 electrons in their outer shell.
No, sodium's outer shell is not stable because it only has one electron in its outer shell. Sodium will readily react with other elements to achieve a stable electron configuration by losing this electron.
Potassium has a valence of +1. This means that it typically forms ions with a positive charge of +1 by losing one electron to achieve a stable electron configuration.
Sodium Na ions have a charge of +1 because they lose one electron to achieve a stable electron configuration. Sodium typically has 11 electrons, with 1 electron in its outermost shell. By losing this electron, it forms a stable cation with a +1 charge.
