Answer:
0,0,0,0
Explanation:
The formal charge formula:
So:
Hydrogen: 1 elec. of valence and shares two electrons with the O
Oxygen: 6 elec. of valence, 2 lone pairs and shares two electrons with the H and two with the F
Fluorine: 7 elec. of valence, 6 lone pairs and shares two electrons with the O
Oxygen: 6 elec. of valence, 3 lone pairs
Note: the dative bond between F and the second O doesn't count as shared electrons.
Answer: D) An Mg atom donates one electron to each of the two Cl atoms.
Explanation: Ionic compound is formed by transfer of electrons from metal to non metal.
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.
Here magnesium is metal with atomic number 12 and chlorine is a non metal with atomic number of 17.
Thus magnesium loses two electrons to form and chlorine atoms gain one electron each to form
Thus the compound formed is .
