gallium Uses, Properties, Facts Britannica

Gallium is amphoteric (i.e., it reacts either as an acid or as a base, depending on the circumstance), reacting with sodium and potassium hydroxide solutions to yield a gallate and hydrogen gas. The halogens attack it vigorously. In most of its compounds, gallium has an oxidation state of +3 and, in a few, +1 (for example, the oxide, Ga 2 O).

gallium Uses, Properties, Facts Britannica

Somewhat similar to aluminum chemically, gallium slowly oxidizes in moist air until a protective film forms. On burning in air or oxygen, it forms the white oxide Ga 2 O 3. This oxide can be reduced to the metal when heated at high temperatures in hydrogen, and with gallium metal at 700 °C (1,300 °F), it gives the lower oxide Ga 2 O.
