Differing number of protons. For example, Hydrogen has 1 proton, whilst Helium has 2 and Lithium has 3.
No two different elements will have the exact same atomic number. Each element has a unique number of protons in its nucleus, which determines its atomic number and distinguishes it from other elements.
Magnesium is different from other elements because of its physical and chemical properties. It is a lightweight metal with a high strength-to-weight ratio, making it valuable for applications in industries such as aerospace and automotive. Magnesium also has a high reactivity with oxygen, which causes it to form a protective oxide layer that makes it resistant to corrosion.
They are usually completely different (metal alloys are the exception). The best example would be sodium and chlorine; a metal that basically explodes on contact with water and a gas which causes people to drown in their own mucus together form a harmless salt that is necessary to human life. They're not related at all. For example- Look at the salt (NaCl). Na (Sodium) atoms are from a soft metal. Cl (Chlorine) atoms are from a yellow-green gas. By combination, they make salt which is neutral. They are different. This is the only thing we can say, since the properties vary from compound to compound and elements to elements.
It is important for scientists to know how elements are similar or different because it helps them understand the properties of different elements, how they interact with each other, and their behavior in various chemical reactions. This knowledge is essential for developing new materials, predicting how substances will behave in different conditions, and advancing scientific research and technology.
If the periodic table was rearranged based on a different organizing principle, the elements would be grouped together in a different way than they are currently. This could potentially change our understanding of the relationships between elements and how they interact with each other.

If there are 109 different elements, there must be 109 different atomic numbers since each element has a unique atomic number that distinguishes it from other elements on the periodic table.
No two different elements will have the exact same atomic number. Each element has a unique number of protons in its nucleus, which determines its atomic number and distinguishes it from other elements.

what happens to the properties of elements when they react with each other element
It is very normal that different compounds or elements have different properties. Each is a specific entity.
All DragonVale hybrids are bred by picking two dragons of different elements to be bred with each other.
An element is made up of only one type of atom. Atoms are only different from each other due to their atomic number - which is the number of protons. Different elements may have different relative atomic masses, but it is the differing number of protons in each atom that determines which element it is.
