"Sodium phosphorus" is not a valid name for a chemical compound, so it's impossible to answer this question. Sodium phosphatewould be Na3PO4. Sodium phosphide would be Na3P. There are other compounds (sodium phosphite, sodium metaphosphate, etc.) which have similar names, each of which has its own formula. You'll need to make it more clear which one you're talking about to get a definitive answer.
The one that will dissociate into TWO ions is (2) NaBrO3 (sodium bromate). It will dissociate into Na^+ and BrO3^-.
NaBr is a formula unit. It represents the simplest, whole-number ratio of ions in an ionic compound, sodium bromide. It does not represent individual molecules but rather the combination of one sodium ion (Na+) and one bromide ion (Br-).
When a compound dissociates, its components separate into individual ions. For example, when table salt (NaCl) dissociates in water, it forms sodium ions (Na+) and chloride ions (Cl-).
The chemical formula for sodium phosphate is Na3PO4, which indicates that each molecule of sodium phosphate contains three sodium ions (Na+) and one phosphate ion (PO4^3-).
Na2S
The formula of the compound containing Na+ and PO43- ions is Na3PO4. This is because the charges of the sodium ion (Na+) and the phosphate ion (PO43-) balance out when three sodium ions combine with one phosphate ion.
The compound formed by Na+ and PO43- ions is sodium phosphate, which has the chemical formula Na3PO4.
The ionic compound formula for sodium bicarbonate is NaHCO3.
The compound formula for sodium sulfide is Na2S. It consists of two sodium ions (Na+) and one sulfide ion (S2-).
The compound is sodium phosphate, which has the formula Na3PO4.
The compound Na2 represents sodium chloride, which is commonly known as table salt. It consists of two sodium ions (Na+) and one chloride ion (Cl-) in a 1:1 ratio.
Sodium sulfate's formula is Na2SO4 because it contains two sodium ions (Na+) for every one sulfate ion (SO4 2-). This combination of ions results in a neutral compound where the total positive charge from the sodium ions balances the total negative charge from the sulfate ion.
In the formula NaCl, there is one Cl- ion for each Na+ ion. This is because NaCl is a 1:1 ratio compound where one Na ion combines with one Cl ion to form a stable compound.
Sodium chloride (NaCl) contains one sodium ion (Na+) and one chloride ion (Cl-). Calcium chloride (CaCl2) contains one calcium ion (Ca2+) and two chloride ions (Cl-). The charges on the ions determine how they combine to form a compound, hence the difference in formulas.
Sodium acetate is a compound. It is made up of sodium ions (Na+) and acetate ions (C2H3O2-).
Table salt has the chemical formula NaCl, which stands for sodium chloride. It is composed of sodium ions (Na+) and chloride ions (Cl-), held together by ionic bonds.
The formula of sodium sulfide, Na2S, indicates that each sodium sulfide molecule contains two sodium (Na) ions and one sulfide (S) ion. The ratio of sodium ions to sulfide ions in sodium sulfide is 2:1.
