Sodium Chloride is an ionic compound. Its molar mass is 58.44g. One formula unit of NaCl consists of one, whose chemical symbol is___ and one___whose chemical symbol is___. Please help me to fill in the gaps :)

One formula unit of NaCl consists of one cation, whose chemical symbol is and one anion whose chemical symbol is

Explanation:

For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.  

The cation is formed by the metal sodium which forms   and the anion is formed by non metal chlorine which forms .

For a formula unit of sodium chloride,  the charges have to be balanced , thus the valencies of ions are exchanged and the neutral compound result. Thus

and   combine to form neutral

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.

the maximum mass of nh3 is nh3 in grams
