Which of the following metals interact with oxygen: lithium, calcium, nickel, iron, gold?

In accordance with the condition of the task, we compose the equations:
1. 4Li + O2 = Li2O – redox reaction (ORR), lithium oxide was obtained;
2. 2Ca + O2 = 2CaO – OBP, calcium oxide is released;
3. 2Ni + O2 = 2NiO – during the OVR process, when heated to 500 degrees, nickel oxide was formed;
4. 4Fe + 3O2 = 2Fe2O3 – OVR, occurs during the smelting of cast iron, iron oxide is released;
5. 2Au + 3O2 = 2Au2O3 – gold oxide is obtained, there is redox reaction on heating.
The decision confirms that all processes are redox processes. Metals: lithium, calcium participate in reactions under normal conditions, and nickel, iron, gold when heated, which is confirmed by their position in the Range of metal activity.
