What characteristic does the alkali metals alkaline earth metals and the halogens have in common?
All alkali metals, alkaline earth metals, and halogens have a common valence electron configuration: alkali metals have 1 valence electron, alkaline earth metals have 2 valence electrons, and halogens have 7 valence electrons. This shared electron configuration influences their chemical properties, such as reactivity and bonding tendencies.
Which set of elements make up the reactive group of all metals?
The reactive group of all metals consists of elements located in Group 1 and Group 2 of the periodic table, known as the alkali metals and alkaline earth metals, respectively. These metals are highly reactive due to their tendency to lose electrons and form positive ions.
What side of a periodic table of elements has metallic properties?
The left side of the periodic table contains elements with metallic properties. These elements include alkali metals, alkaline earth metals, transition metals, and basic metals. Metals tend to have high electrical conductivity, luster, malleability, and ductility.
What metals react violently with acid?
Metals such as sodium, potassium, and lithium can react violently with acids. These reactions can produce heat, hydrogen gas, and cause the acid to splash. Special precautions should be taken when working with these reactive metals to prevent accidents.
Are alkali earth metals reactive?
Alkali earth metals are less reactive than alkali metals but they still react readily with oxygen and water, forming oxides and hydroxides. They are stored under oil or inert gases to prevent them from reacting with moisture in the air.
Are alkali earth metals liquids?
no, the alkali metals make up the first period and all of them are highly reactive.
What characteristics are shared by all alkali metals and alkaline earth metals?
They are highly- reactive metals
What is the metal that reacts explosively with acids?
All alkali metals and alkali earth metals below calcium react vigorously with acids.
Metals that are less reactive than alkali metals and alkaline-earth metals are?
Almost all the rest of the metals.
What important characteristics do the alkali metals and earth metals have in common?
They all have at least one electron.
Why alkali metals are more reactive than alkaline earth metals?
All atoms want to do is make their valence shell full. In alkali metals they have all of their shells completely full except one valence electron. The alkali metals REALLY want to get rid of that electron, so they will react with many elements/compounds to get rid of that electron. In alkaline earth metals they have all of their shells completely full except for two valence electrons. They also want to get rid of those electrons but the alkaline earth metals are not as desperate to do so as the alkali earth metals which make the alkaline much less reactive than the alkali metals.

List all the alkali metals?

Is the alkali metal more reactive than an alkaline-earth metal?
Yes, alkali metals are more reactive than alkaline-earth metals. All atoms want to have 8 electrons in their outer shells. Alkali metals have to give one electron away, where as alkaline-earth metals need to give two away which is less energetically favorable.
Alkali metals alkaline earth metals and aluminum all form ions with postivie charges equal to the?
the group number
