Sodium and magnesium have a valency of 1 because they have 1 electron in their outermost energy level. By losing this electron, they achieve a full outer shell and become stable with a positive charge of +1.

How will you find the valency of chlorine sodium and magnesium?

Look in the periodic table at groups; sodium has the valence +1, magnesium +2 and chlorine -1.


What is the valency of an element sodium chloride?

Sodium chloride is composed of sodium (Na) and chlorine (Cl). Sodium has a valency of +1, while chlorine has a valency of -1. In sodium chloride, sodium donates its electron to chlorine, forming an ionic bond with a valency of +1 for sodium and -1 for chlorine.


What is valency of sodium?

The valency of sodium is +1. Sodium is an alkali metal with one electron in its outermost shell, which it tends to lose in chemical reactions to achieve a stable electron configuration.


What is the valency of sodium phosphate?

The valency of sodium is +1, and the valency of phosphate is -3. Therefore, the valency of sodium phosphate (Na3PO4) is +1/-3, resulting in an overall valency of +1.


What is the symbol and valency for Sodium ion?

Symbol for sodium cation is 'Na(+)' Its valency is '1'.


What is the valency of sodium sulphate?

The valency of sodium in sodium sulfate is +1, while the valency of sulfate is -2. Therefore, the valency of sodium sulfate as a whole is +2.


What is the valency magnesium?

magnesium has a valency of 2


What is the valency of sodium thiosulphate?

The valency of sodium thiosulfate is determined by breaking down the compound into its constituent ions. In this case, sodium has a valency of +1 (Na+), and thiosulfate has a total charge of -2 (S2O3^2-). Therefore, the valency of sodium thiosulfate is +1 because it has one sodium ion for every thiosulfate ion in the compound.


Why is the valency of sodium one?

The sodium cation is Na+. The valence of sodium is +1.


What is the valency of magnesium sulphate?

The valency of magnesium in magnesium sulfate is +2, as magnesium typically forms ions with a charge of +2. Sulfate (SO4) has a valency of -2 because it usually gains two electrons to achieve a stable octet.


What is the valency of Sodium in Na2Co3?

0The valence of Na in this compound is +1 and of Carbonate it is -2However it is better to use: ionic charge or -number,So, when dissolved in water, you get:Na2CO3 -> 2 Na+ + CO32-


Why the valency of Na is not 4 in NaCl crystal?

Sodium (Na) typically has a valency of +1 because it has one electron in its outer shell, which it tends to lose to achieve a stable electron configuration. In a NaCl crystal, sodium loses one electron to chlorine (Cl), which has a valency of -1, resulting in an overall neutral compound with a 1:1 ratio of Na and Cl ions.
