Yes, gold (Au) is less reactive than magnesium (Mg). Magnesium is more reactive because it readily loses electrons to form positive ions, while gold is relatively unreactive.
Potassium (K) is more reactive than magnesium (Mg) because potassium is a more reactive metal due to its lower position in the reactivity series. Potassium reacts more violently with water and air compared to magnesium.
Magnesium (Mg) is more reactive than aluminum (Al) because it is higher up in the reactivity series of metals. This means that magnesium can easily lose electrons to form positive ions in chemical reactions compared to aluminum.
Mg is more reactive than Zn because Mg has a lower electronegativity than Zn, meaning it is more likely to lose electrons in a reaction. Additionally, Mg has a smaller atomic radius, allowing it to react more readily due to stronger electron-nucleus interactions.
The most reactive series is the reactivity series of metals, which ranks metals from most reactive to least reactive based on their tendency to undergo chemical reactions. The series is a useful tool in predicting how metals will react with other substances.

A more reactive metal pushes out a less reactive metal out of a compound element, eg. CuSo4+Mg=MgSo4+Cu
The stranded cell notation for a galvanic cell made with magnesium (Mg) and gold (Au) is written as: [ \text{Mg(s)} | \text{Mg}^{2+}(aq) || \text{Au}^{3+}(aq) | \text{Au(s)} ] In this notation, the anode (Mg) is on the left side, while the cathode (Au) is on the right, with a double vertical line (||) representing the salt bridge that separates the two half-cells.
Barium is more reactive than magnesium.

Barium (Ba) is more reactive than magnesium (Mg) because as you move down a group on the periodic table, reactivity tends to increase. Barium is located below magnesium in Group 2 of the periodic table, which means it has an additional electron shell that is further away from the nucleus, making it easier to lose electrons and react.
