Are there storms with lightning over Antarctica? If yes what happens when a bolt of lightning strucks the ice?

Thunderstorms are unlikely over Antarctica because thunderstorms generally require instability and moisture, both of which are rare at the polar south. If you live where there's snow in the winter, you may have noticed how it rarely, if ever, thunders during the winter. This is the reason why.  Even during the warmest months of the Antarctic summer, the hottest it'll get is around 0 degrees Celsius so it's very unlikely for thunderstorms to occur in the Antarctic. In the event where there is lightning and snow as the precipitation, this is known as thundersnow. As for the second part of your question, ice is a bad electrical conductor so it can be surmised that when lightning strikes the ice, the ice will fragment/melt/explode at the point of impact and then refreeze.
