Answer:

#K_2O#

Explanation:

Potassium has a tendency to lose #1# electron to become #K^+#, while oxygen wants to gain #2e^-# to complete its octet, so it becomes #O^(2-)#.

Combining,

#K^+##O^(2-)#

We have to criss cross, so the #2# goes to potassium, while #1# goes to oxygen, so our final formula is:

#K_2O#

This is a compound called potassium oxide.
