Alkaline earth metals, such as magnesium and calcium, do react with air. When exposed to oxygen, they form oxides or hydroxides on their surface, which can give them a characteristic dull appearance. The reactivity increases as you move down the group from beryllium to radium.

What are metals that are less reactive than alkali metals and alkaline-earth metals?
Transition metals such as copper, silver, and gold are less reactive than alkali metals and alkaline-earth metals. These metals are less likely to react vigorously with water or air compared to alkali and alkaline-earth metals.
How does alkaline earth metals react?
Alkaline earth metals are reactive and tend to lose two electrons to form a 2+ cation. They react with water to produce hydrogen gas and hydroxide ions. They also form oxides when they react with oxygen in the air.
What does a alkaline earth metal react to easily?
Alkaline earth metals react easily with water and oxygen in the air to form oxides or hydroxides. They are less reactive than alkali metals, but still exhibit a high reactivity compared to other elements.
Why do alkaline metals and alkaline-earth metals reactso violently?
Alkali metals and alkaline-earth metals react violently with water or air because they have low ionization energies, meaning they readily lose electrons to form positive ions. When they react, they release a large amount of energy as heat and produce hydrogen gas. This rapid release of energy and gas can result in explosions or violent reactions.
Do alkaline metals react with oxygen?
Yes, both the alkali metals and the alkaline earth metals with react with oxygen. The alkali metals will do so rapidly even at room temperature, cesium and rubidium self-ignite on contact to air.

Do alkali metals react slower or faster than alkaline earth metals?
Alkali metals react faster than alkaline earth metals due to their lower ionization energy and higher reactivity. Alkali metals readily lose their outermost electron to form a +1 cation, making them highly reactive with water and air. Alkaline earth metals, on the other hand, are less reactive as they have higher ionization energies and require more energy to lose their outer electron.

What metals are reactivie?
Reactive metals include alkali metals (e.g. lithium, sodium, potassium) and alkaline earth metals (e.g. calcium, magnesium). These metals react easily with water, air, and acids to form various compounds. Additionally, transition metals such as iron and aluminum are also considered reactive due to their tendency to undergo oxidation reactions.
What are some dangers of working with alkaline eath metals?
Alkaline earth metals such as magnesium, calcium, and barium can react vigorously with water or air, producing flammable hydrogen gas. They are also toxic when ingested, and can cause skin irritation if handled without proper precautions. Additionally, alkaline earth metals can form explosive compounds if not stored or handled correctly.
Which two families in the periodic table have the most reactive metals?
The alkali metals (Group 1) and the alkaline earth metals (Group 2) are the two families in the periodic table with the most reactive metals. Alkali metals are more reactive than alkaline earth metals due to their lower ionization energy and higher reactivity with water and air.
Are alkali metals and alkaline earth metals always found combined in nature?
They react easily. They combine with other elements to complete/fill their outer shell.
What do metals react with that is found in the air?
group one and two metals react with oxygen in the air as well as moisture to from metal oxides
Is alkaline flammable?
Alkaline substances are generally not flammable on their own. However, certain alkaline metals such as lithium, sodium, and potassium can react violently with water or air, leading to combustion. These reactions are highly exothermic and can produce flammable hydrogen gas.
