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.
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.
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.
Does calcium and barium have similar or different reactivities?
Calcium and barium have similar reactivities, because they are both alkaline earth metals. Quantitatively, barium is slightly more reactive than calcium because it has more electron shells between its valence electrons and its nucleus.
What are the most reactive metals called?
The most reactive metals (those in the first group of the periodic table) are called Alkali metals.
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
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.
Is alkali metals highly reactive because of its one valence electrons?
Yes, alkali metals will react with anything to get rid of that one valence electron, which makes them highly 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).
What term describes the most reactive non metals that have 7 valence electron shields?
They are basically called halogens.
How many valence electron does alkali metals have?
Alkali metals have one valence electron.
What metals are the farthest left side of the periodic table?
They're called the alkali metals, and they all have 1 valence electron, which means they are the most reactive of all the metals.
Alkali metals are extremely reactive because?
because they have one valence electron that is easily removed to form a positive ion.
