Na2S
Na2+1O11-
The compound formed by Na+ and PO43- ions is sodium phosphate, which has the chemical formula Na3PO4.
The chemical formula for sodium selenide is Na2Se.
Back is for salt

2 Neutrons, WHY? NA=NOTHING 1=1 YES? The own neutron it is in = 1 the plus 1+1 = 2 neutrons
The chemical equation is:6 Na + 2 O2 = 2 Na2O + Na2O2
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.
Nothing OR plus 1.
