Which group of metals is characterized by a single valence electron and are very reactive atoms?
Alkali metals
What else can I help you with?
What are the most reactive metals called?
The most reactive metals are called alkali metals. This group includes elements like lithium, sodium, and potassium, which readily react with other elements due to their low ionization energy and tendency to lose an electron to achieve a stable electron configuration.
What do all elements group 1 have in common in terms of electrons?
Group A1 of the Periodic Table (Hydrogen, Lithium, Sodium . . . ) is an Alkali Metal and only has one valance electron. If the element were to lose that electron, it forms an ion. Each element violently reacts when combined with water.
How many valence electrons does the element cesium have?
A cesium atom has 1 valence electron. It is an alkali metal, and all alkali metals have 1 valence electron. The electron configuration for cesium is (Rn)7s1. The single electron in the 7s sublevel is its valence electron.
The force of attraction by group 1 metals for their valence electrons is?
The force of attraction by group 1 metals for their valence electrons is weak. This is because group 1 metals have a single valence electron that is loosely held and easily lost to form positive ions.
How can you tell that sodium is in group 1 from its electron structure?
Sodium has one valence electron. As you move left to right on the periodic table in the columns, the amount of valence electrons increases. It may get a little trickier for transition metals, but that is a separate question.
Which group of metals is characterized by a single valence electron and reactive atoms?
Alkali metals
What type of metals such as sodium have a single valence electron are very reactive?
Highly reactive metals with one valence electron are known as 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 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.
What type of metals such as sodium have a single valence electron and are reactive?
alkali metals
Which group of metals is charterised by a single valence electron and very active atoms?
Alkali metals, such as sodium and potassium, are characterized by having a single valence electron and very reactive atoms. They readily lose this outer electron to form +1 cations in chemical reactions.
Is alkali metals highly reactive because of its one valence electrons?
Yes, alkali metals are highly reactive because they have one valence electron that they readily donate to achieve a stable electron configuration. This makes them extremely reactive with water and air, which results in explosive reactions.
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.
What do the alkali group 1 metals have in common?
Alkali group 1 metals have one valence electron, which makes them highly reactive. They have low melting and boiling points and are soft metals that can be easily cut with a knife. These metals also tend to form ionic compounds due to their tendency to lose their single valence electron.
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.
What group of metals is characterized by a single valence electrons and very reactive atoms?
The alkali metals easily yield the one electron found in their valence shell, to bond with other elements. Since it takes so little energy to remove this electron from an alkali metal (i.e., they have a low ionization energy) these metals are never found in nature in their elemental forms (they are too reactive; i.e., their atoms so easily bond to other atoms).
How many valence electrons do alkaline earth metals have?
The alkali earth elements have TWO valence electrons.
