Why Elements are aleways combined in a compound with another element why does this occur?

That's because of the way "compound" is defined. If atoms of an element combine with other atoms of the SAME element, then it's not called a "compound".


Does an element become a compound when the type of atoms is changed?

Yes, the element changes to compound when atoms of it changes because compound is made up of different types of element and the element is made up of different types of atoms when the atoms are changed the element also changes and different types of elements are made due to this the element is changed to a compound.
