An alkali metal is any Group 1 metallic elements: lithium, sodium, potassium, rubidium, cesium and francium; all are strongly reative, soft low density metals. Which means if they come in contact with a halogen it can cause a vigorous reaction.
Yes
Alkali metals are from Group 1 of the Periodic table and have a single electron in their outer shell. Alkaline-Earth metals are in group 2 of the periodic table and have 2 electrons in their outer shell.
Highly reactive metals that easily combine with other elements are called alkali metals, like sodium and potassium. They react vigorously with water and oxygen.
They metals are stored in oil to minimize the reactivity with air. When alkali metals react with air, they quickly tarnish after begin cut, they burn easily.
No, cesium is an alkali metal. Metals do not react with one another. Cesium reacts with nonmetals and acids to form salts.
Yes
All alkali metals and alkali earth metals below calcium react vigorously with acids.
Alkali Earth metals are the most reactive metals on the periodic table.
Alkali metals react vigorously with water, producing hydrogen gas and forming alkaline solutions. They react with oxygen to form oxides, and with noble gases they can form compounds under certain conditions, although the reactivity is not as intense as with water or oxygen.
They do react vigorously.
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.
Alkali metals are all of the elements on the far left hand side of the Periodic Table with the exception of hydrogen. They are all highly reactive metals that also react vigorously with water.
They don't
Many. All the alkali metals will react explosively with it. All the alkaline earths will also react extremely vigorously. Group 3 metals from Al and below will and many transition metals do also. Copper, silver and Gold do not.
alkali metals react violently in cold water
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.
No, Acids react with metals to form salts.
