When Na and Cl combine to form a compound which atom will become a cation?
Sodium will become a cation with a 1+ charge and the formula Na+.
What is the ratio of atoms for the compound NaCl?
The ratio Na/Cl is 1 in the formula unit.
What is the charge on ions formed from atoms of Na?
because Na has one electron in its outer shell, the charge of the ion is Na+
What subscripts would most likely be used if an alkali metal and a halogen formed an ionic compound?
1 and 1
Why is sodium fluoride a compound?
Na has 1 valence electron, Cl has 7. Therefor the 1 electron from the Na goes onto the Cl so that both have a full set of valence electrons.
What is the name of the compound when Na plus and CI-1 are combined?
The compound formed when Na+ and Cl- are combined is called sodium chloride (NaCl).
Is sulfate a atom?
No. Sulfate is a compound. It is a combination of atoms: 1 atom of Sulfur and 3 atoms of Oxygen. SO42-
What is the formula for the compound Na plus O?
Na (sodium) has a valence of 1+ and oxygen (O) has a valence of 2-, so it will take 2 Na for each O. The compound formed (sodium oxide) has the formula Na2O.
What charge will the ion formed by sodium?
+1 Na+ ion is formed
What is the formula for ionic compound of sodium nitrate?
Na+1 NO3- => Na(NO3)
What is the oxidation numbers in the compound NaCl?
+1 for Na -1 for Cl
What is the total molar concentration of ions in a 0.350 M solution of the strong electrolyte Na2SO4 assuming complete dissociation?
1 mol Na2SO4 will dissociate to 2 mol Na+ and 1 mol SO42- Therefore 0.350 M Na2SO4 will dissociate to 0.350*2 = 0.700 mol Na+ and 0.350*1 = 0.350 mol SO42- Therefore the total concentration of ions is 0.700 mol + 0.350 mol = 1.050 mol.
What is the correct formula for a compound formed between sodium and sulfate ions?
Na + have a charge of +1 sulphates SO4 2- have a charge of -2 Somehow the formula must cancel out and render a neutral molecule Thus the formula is '''Na2SO4 '''the compound is called sodium sulphate
Can ionic compounds be composed of 1 cation and 2 anion?
Yes. For example NaHSO4. Here there are two cations, Na+ and H+, and one anion SO42-. As long as the charges balance out and equal zero, there can be an infinite number of cations and anions in a given compound.
What is the ion formed by a sodium atom called?
Sodium, Na, is in group 1 of the periodic table, so to achieve a complete valence shell, it forms a cation with a charge of 1, Na1+.
Is sodium chloride a mixture or a compound?
Sodium Chloride is a compound made up of Na+ and Cl- ions in a lattice arrangement in a 1:1 ratio
Is sodium perbromate a polyatomic ion?
Sodium perbromate is not a polyatomic ion. It is an ionic compound formed by combining sodium (Na +1 ) ions with perbromate ions (BrO4 -1). Perbromate by itself would be a polyatomic ion.
