Na is a cation (positive) and F is a anion (negative) this is an ionic bond. In a ionic bond the cation loses its valence electrons to give them to the anion. In this case Na will give its valence electron to F so F can complete its octet:)
Answer:
The smallest possible inside length of the tank is 
m.
Explanation:
As we know that
Thus, volume of 
liter tank is also equal to 
cubic meter
The volume of a cube is equal to 
, where, x is the length of the side of the cube
With the give condition,
Solving the above equation, we get -
The smallest possible inside length of the tank is m.
