Because of physical change
Alkali earth metals react with oxygen to form basic oxides.
Water and oxygen can be used to compare the reactivity of metals. More reactive metals will react with water to form metal hydroxides and hydrogen gas, and with oxygen to form metal oxides. Less reactive metals may not react with water or oxygen at all.
Alkaline-earth metals are less reactive compared to alkali metals, but they still react with water and oxygen to form oxides and hydroxides. They are more reactive than transition metals but less reactive than alkali metals.
Titanium is more reactive than cobalt. Titanium is known for its high reactivity with oxygen, forming a protective oxide layer on its surface. In contrast, cobalt is less reactive and more resistant to corrosion.
The pattern of reactions of metals with oxygen is based on their position in the reactivity series. Highly reactive metals like potassium, sodium, and calcium react vigorously with oxygen to form metal oxides. Less reactive metals like iron and copper react slowly with oxygen, forming metal oxides or hydroxides. Noble metals like gold and platinum do not react with oxygen at all under normal conditions.
Titanium has a relatively low thermal expansion coefficient compared to other metals, meaning it expands less when heated. This property makes it useful in applications where dimensional stability is important.

The main advantage of using a titanium money clip over other money clips is that titanium is stronger than other metals. Thus, it is less likely to let the money fall out of the money clip.

Silicon is considered to be a relatively reactive element. It reacts with oxygen to form silicon dioxide (silica) and can also react with certain metals and nonmetals to form various compounds. However, silicon is more stable and less reactive compared to some other elements like alkali metals or halogens.
Stronger is a difficult word to define in terms of metals. What you can say is tungsten is harder than titanium, and as a result of being harder it is more difficult to scratch and going be less likely to tarnish. Hence, why both metals have become very popular as tungsten wedding bands and titanium wedding bands, due to the ability to resist scratching and tarnish better than gold bands.
Yes, metals can sink in water depending on their density. Metals such as iron and lead are denser than water, so they will sink. Other metals like aluminum and titanium are less dense than water and will float.

Highly reactive metals like potassium, sodium, and calcium react vigorously with oxygen to form metal oxides. Less reactive metals like iron and copper react slowly with oxygen, forming metal oxides or hydroxides. Noble metals like gold and platinum do not react with oxygen at all under normal conditions.
Metals of medium reactivity can react well with acids, water, and oxygen. They tend to corrode or rust when exposed to oxygen in the atmosphere, react with acids to produce hydrogen gas, and can displace less reactive metals from their compounds in aqueous solutions.
No, titanium is less reactive than sodium.
