What else can I help you with?
Does rubidium have one valence electron?
Yes. Rubidium is an alkali metal, and all alkali metals have one valence electron.
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 many valence electrons does an alkali metal have?
An alkali metal has 1 valence electron. Group 1 elements, such as lithium, sodium, and potassium, all have 1 valence electron in their outermost energy level.
What happens to the valence electron in an alkali metal when it combines with a halogen gas?
This electron is lost.
How many valence electrons are present in rubidium?
Rubidium has one valence electron as it an alkali metal.
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 element is a metal with 2 valence electron?
All alkali earth metals have 2 valence electrons.
How many valence electrons are in rubidium?
1 valence electron. It is an alkali metal and all alkali metals have one atom on their last energy level.
The outer electron configuration of an alkali metal has?
The outer electron configuration of an alkali metal is one electron in the s subshell. This electron is easily lost to form a cation with a full valence shell, resulting in the high reactivity of alkali metals.
Why will an alkali metal often combine with a halogen nonmetal to form a compound?
Well, the "happy" number in chemistry is eight. And alkali metals have one valence electron while halogens have seven so when they combine, the combination has eight valence electrons. This means it is full.
Number of valence electrons in Lithium?
There is one valence electron in lithium, also in every other alkali metal element.
Which element region will most readily react to form an ionic compound with alkali metal?
This is the valence electron.
