Alloys are supposed to give greater strength to metals, which is why gold is mixed with others to make it harder. They have greater strength and are more resistant to erosion.

Chemistry

Because more energy is required to form $O^{6+}$ ion.

Explanation:

Oxygen is the 8th element of the periodic table which belongs to Group 16.

The electronic configuration of the element is: 1s^22s^22p^4

The number of valence electrons are 6 which is not a stable electronic configuration.

To attain stable electronic configuration, this element will either loose 6 electrons to form $O^{6+}$ ion or gain 2 electrons to form $O^{2-}$ ion.

The loosing of 6 electrons require a huge amount of energy and is an unfavorable reaction. Hence, this element will gain 2 electrons easily and form $O^{2-}$ ion.

This element is considered as a non-metal because it gains electron to attain stable electronic configuration.
