No, If in any Pokemon game electric beats ground, I've seen EVERYTHING.
Ground beats Electric though.
Electric type moves aren't really effective against grass type Pokémon, but it is possible with the right set of moves.
Rock and ground types
for electric gyms, a ground type with earthquake is perfect and you get stab and electric pokemons defenses are low normally. it doesn't have to be a ground type Pokemon but ground is the only weakness to electricity. Mud shot, mud bomb, dig and earthpower are other moves aswell to KO electric. Mud sport is useful as it weakens electrics power and ground types have an immunity altogether. If all this fails, a strong physical move should do the trick
rock ground flying grass
fire ground rock
All you need is a ground type pokemon or a ground type move
GROUND
Electric types cannot attack ground types.
Electric-types only have one weakness and that's Ground-type. Any Pokemon can defeat Electric-types, but using a Ground-type will likely have a super effective, making the Pokemon faint quicker.
GROUND
Rock and ground types
ONLY ground types. however, some ground type pokemon, ( like cubone or marowak ) have the ability "lightningrod" witch prevents electric type moves for effecting them. electric types don,t effect ground types anyway.

The 8th Gym Leader has electric type pokemon. Your best bet to defeat him is Ground or Rock pokemon. Electric types are not effective against ground types.
Ground types are great against electric types so find yourself a decent ground type Pokemon and train it a bit then use it.
