because Na- is sodium and the charge for sodium is +1
but NO3 is a -1
so when you Cris cross them:
your formula should look like this.
Na+1NO3-1= +1 and -1 cancel out and you are left with NaNO3
:) hope it helped.
Cations are 2 aluminium (Al3+).
Anions are 3 sulfate - (SO4)3-.
Na+(cation) O2-(anion)
One atom of Oxygen
This compound doesn't exist.
There are two sodium atoms in each molecule of Na2O, as indicated by the subscript immediately after the symbol for sodium atoms in the formula.
765 g of Na2O have 193,55 g oxygen.
The chemical formula for sodium oxide is Na2O (with the '2' written in subscript). So in one formula unit of sodium oxide, there is one sodium and two oxygen. 1 mole of sodium oxide would have 3 x 6.02 x 10^23 = 1.81 x 10^24 atoms.Sodium oxide is made of sodium and oxygen atoms. The chemical formula of it is Na2O. There are 3 atoms in 1 molecule of Na2O.
Na2O is sodium oxide. It contains the elements, sodium and oxygen. The chemical formula tells us that there are 2 sodium atoms and 1oxygen atom . It is a highly reactive compound, which will readily dissolve in water to form sodium hydroxide. Na2O + H2O = 2NaOH .

Sodium oxide is a compound, two sodium atoms for each oxygen atom, or Na2O (if I could do the subscript).
Nothing.4 atoms of sodium would have a 4 + charge and 5 atoms of oxygen would have a 10 - charge.So you need 2 atoms of sodium and 1 atom of oxygen to get...,Na2O=====
The compound Na2O is formed through a reaction between sodium metal (Na) and oxygen gas (O2). During this reaction, the sodium atoms lose electrons to become positively charged ions (Na+), while the oxygen atoms gain electrons to become negatively charged ions (O2-). These ions combine to form the ionic compound Na2O.
Na2O is sodium oxide. It contains the elements, sodium and oxygen. The chemical formula tells us that there are 2 sodium atoms and 1oxygen atom . It is a highly reactive compound, which will readily dissolve in water to form sodium hydroxide. Na2O + H2O = 2NaOH .
