Do Alkali earth metals react with oxygen?
Alkali earth metals react with oxygen to form basic oxides.
Which metal is more reactive titanium or cobalt?
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.
Which two substances can be to compare the reactivity of metals other than acids?
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.
Are alkaline-earth metals reactive?
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.
Pattern of reactions of metals with oxygen?
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.
Does titanium expand a lot when heated compared to other metals?
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.
Do Alkali earth metals react with oxygen?
Alkali earth metals react with oxygen to form basic oxides.
Where is yttrium on the reactivity scale?
Yttrium is classified as a moderately reactive metal. It is part of the lanthanide series and typically reacts with oxygen and water, although it does so less vigorously compared to alkali metals. Yttrium's reactivity increases with temperature, and it forms stable oxides when exposed to air. Overall, it is more reactive than transition metals but less so than alkaline and alkaline earth metals.
What are the main advantages of using a titanium money clip?
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.
Is Fe very reactive?
Iron (Fe) is moderately reactive compared to other metals. It readily reacts with oxygen in the presence of moisture, leading to oxidation and rust formation. However, it is less reactive than alkali metals and alkaline earth metals. In general, while iron can participate in various chemical reactions, it does not react explosively or violently under normal conditions.
Which metal is more reactive titanium or cobalt?
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.

Are alkaline-earth metals reactive?
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.
How reactive is silicon?
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.
Is a titanium rings stronger then a tungsten rings?
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.
Was metal sink in water?
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.
Pattern of reactions of metals with oxygen?
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.
