Element B is more reactive because it needs only one electron to attain stability. Both elements are non-metals, so they share electrons to form covalent bonds, resulting in the molecular compound AB3 or PCl3.
The atomic number is 11 and mass number is 23. It is a positively charged cation because protons exceed electrons by one. Its electronic configuration is 2, 8 and the species is a sodium ion, Na+.
The total mass of reactants equals 5.3 g plus 6.0 g, which is 11.3 g. The total mass of products equals 2.2 g plus 0.9 g plus 8.2 g, which is 11.3 g. Since reactant mass equals product mass, the ...
Row NH4+: NH4NO3, (NH4)2SO4, (NH4)3PO4. Row Li+: LiNO3, Li2SO4, Li3PO4. Row Al3+: Al(NO3)3, Al2(SO4)3, AlPO4. Row Cu2+: Cu(NO3)2, CuSO4, Cu3(PO4)2. Each entry balances the positive and negative charges of the combining ions.
