Because sodium loss only one electron from the outer electron shell and become a cation with the charge +1.
The ions that are present in the solution of sodium phosphate is the sodium ions and the phosphate ions. The sodium ion has +3 charge while the phosphate ion has the -3 charge.
Na+ ions
Sodium is an elemental metal, found in the Periodic Table. When it ionises( looses) an electron it becomes the Sodium CATION (Na^(+)). Remember ions that have a positive charge are CATIONS, and ions that have a negative charge are ANIONS. Slo the chloride ion (Cl^-) is an ANION. Collectively they are ions.
The cation Na+.
lose an electron, forms Na+, sodium with a charge of plus one.
Na+ (sodium, plus one charge) OH- (hydroxide ion, one oxygen and one hydrogen, minus one charge)
because Na has one electron in its outer shell, the charge of the ion is Na+
The ions that are present in the solution of sodium phosphate is the sodium ions and the phosphate ions. The sodium ion has +3 charge while the phosphate ion has the -3 charge.
NaI is sodium iodide
0
Sodium is as the cation Na+; and the anion is (OH)-.
Na+ ions
Two Na plus ions will combine with an O2- to form the basic compound sodium oxide. When water is further added, the neutral salt, sodium hydroxide is formed.
Sodium is an elemental metal, found in the Periodic Table. When it ionises( looses) an electron it becomes the Sodium CATION (Na^(+)). Remember ions that have a positive charge are CATIONS, and ions that have a negative charge are ANIONS. Slo the chloride ion (Cl^-) is an ANION. Collectively they are ions.
Na+ ions (monovalent +1)
Sodium is the cation (+1 charge), sulfate is the anion (-2 charge) The chemical formula tells us there are two sodium ions (Na2) and one sulfate (SO4) ion.
Na+ and Cl- are spectator ions.
