    Where to attach neutral/ground in breaker panel

    Installing an over the range microwave, ran the (yellow) wire to the box, but where can I attach the ground and neutral wires? The one bus on the right is full, the second bus on the right is empty, but can I use it? Nothing else is attached to it.
