A. Fewer valence electrons
Valence electrons are electrons that are held most loosely in the outermost shell.
Rate of effusion gas/rate of effusion H2 = √(M(H2))/√(M(gas))
0.344= √2/√(M(gas))
√(M(gas))= √2/0.344
M(gas)= (√2/0.344)² =2/(0.344)² ≈16.9

Answer:
Decrease by the distance squared
Explanation:
<u><em>Gravitation formula:</em></u>

where
'F' is the force of attraction between the two bodies (Gravitational force),
'G' is the universal gravitational constant,
'M' is the mass of the first object,
'm' is the mass of the second object and
'r' is the distance between the centers of each object.
Hence, with the increase by distance between two objects , the gravitation decreases by the distance squared
