Because of the interaction between each element's sub atomic particles. Magnesium has its specific properties because of the way it's electrons are arranged. Oxygen has different properties because it has a different electron arrangement. When combined, the resulting molecule is larger and has a different, more complex arrangement of sub atomic particles interacting with each other.
It is a compound.
Nitrogen and oxygen are individual elements with different properties.
Yes
The answer is in the question. Magnesium is an element, so is oxygen, together they can form MgO, a compound, as compounds are multi atomic structures, like Iron Oxide, another rust just like MgO.
Air is composed of many different gases that are not chemically combined and retain their individual properties. Water is a compound because it is composed of two hydrogen atoms chemically bonded to an oxygen atom, and the properties of water are different from the properties of the elements hydrogen and oxygen.

reacts with oxygen in air to produce magnesium oxide.
reacts with oxygen in air to produce magnesium oxide.
Yes
Oxygen and ozone are completely different in properties. Ozone is a pollutant on breathing, while oxygen is not.

it is soluble (sulphates get less soluble as you go down the group in the periodic table)
Oxygen and ozone have different properties. It is because of their atomic structure.
No. They are two completely different substances. Magnesium chloride (MgCl2) is a water soluble compound of magnesium and chlorine. Magnesium oxide is a water insoluble compound of magnesium and oxygen.
