What type of metal such as sodium have a single valence electrons and are very reactive?

Highly reactive metals with one valence electron are known as Alkali metals.


Which column contains the most reactive elements?

The column that contains the most reactive elements is the alkali metals column, which is the first column in the periodic table. Alkali metals are highly reactive due to having only one electron in their outer shell, making them eager to lose this electron and form positive ions.


What is the most reactive group on the left side?

The most reactive group in the periodic table is group one, the alkali metals.


What type of metals such as sodium have a single valence electron and very reactive?

Highly reactive metals with one valence electron are known as Alkali metals.


What is group one in the periodic table?

Alkali metals. This is the most reactive group on the periodic table


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.


What is family one called in the periodic table?

alkaline earth metals


Why is alkali the most reactive metals?

Alkali metals are the most reactive group of metals because they have one valence electron that they readily donate to achieve a stable electron configuration. This makes them highly reactive with other elements, especially water and oxygen. They react vigorously, often producing heat and releasing hydrogen gas.


Why are alkali metals more reactive than other metals?

Alkali metals are more reactive as they are in group 1 and therefore has only one valence electron. With only one valence electron, its easy for them to achieve inert configuration/ noble gas configuration, which makes them so reactive.


Which periodic table famiy is the most reactive?

The alkali metals family, which includes elements like lithium and sodium, is the most reactive group on the periodic table. These elements readily give up their outermost electron to form a +1 oxidation state, leading to high reactivity with other elements.


What are the most reactive families on the periodic table and why are they the most reactive?

The alkali metals Lithium, Sodium, Potassium, Rubidium cesium and Francium is the most reactive group of metals. They are this way because they only need to lose one electron to gain a stable octet which is very favorable energetically. The most reactive group of non-metals is the halogens, Fluorine, Chlorine, Bromine, Iodine and Astatine. These are the exact opposite. They are extremely reactive because they only need to gain one electron to gain a stable octet which is again, highly energetically favorable.


How are alkaline earth metals different from alkali metals in terms of their properties and reactivity?

Alkaline earth metals have higher melting points and densities compared to alkali metals. They are less reactive and have two valence electrons, while alkali metals have one valence electron and are more reactive.
