Question

why do xe forms compounds only with flourine and oxygen​

Answer 1

Not all the noble gases combine with oxygen and fluorine. Only the heavier noble gases like Xe, etc will react with oxygen and fluorine. Noble gas form compounds with oxygen and fluorine only because they are most electronegative elements. So they can ionise noble gases also.

Answer 2

because they both are high eleconegtivity in periodic table so Xe only forms compound with F and O2
