The elements with only one valence electron are a part of the Alkali Metals:
* Lithium * Sodium * Potassium
* Rubidium * Cesium * Francium Hydrogen also only has one valence electron, but it is not considered part of the Alkali Metals family, nor any other family.

∙ 13y agoIn addition to hydrogen, all elements in Group I of the periodic table have one valence electron. They are lithium, sodium, potassium, rubidium, cesium, and francium.
The farther you move right on the Periodic Table the more valence electrons. For example, elements in Group VII have 8 valence electrons except helium.

What element has one valence electron and is very reactive?
Sodium.
What element has one valence electron but is not a metal?
There is no non-metal with one valence electron. Every element with 1 valence electron belongs to the alkali metals family
Element 3 lithium has one valence electron and element 4 beryllium has two valence electrons Element 5 boron has how many valence electrons?
Boron has 3 valence electrons.Boron has 3 valence electrons.
If an element has 1 valence electron what group is it in?
That element would be in the Alkali Metals (group one)
Which Element Has One Valence Electron And Is In Period 4?
The element would be potassium (K).
What element has only one valence electron and is extremely reactive?
HYDROGEN
How many valence electrons should an element to react with a element with 7 valence electrons?
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.
What element has the same valence electron configuration as phosphorus?
The answer is nitrogen. Nitrogen is one example of an element that has the same valence electron configuration as phosphorus.Ê
What element has the same valence electron configuration as phosphorus p?
The answer is nitrogen. Nitrogen is one example of an element that has the same valence electron configuration as phosphorus.Ê
What element has one valence electron calcium or potassium?
Potassium has one.
What element has one valence electron and is very reactive?
Sodium.
What element can only have a valence of 1?
Hydrogen. Since it has room to gain or lose no more than one electron in its single shell, it can therefore only have a valence of 1.
What element has one valence electron but is not a metal?
There is no non-metal with one valence electron. Every element with 1 valence electron belongs to the alkali metals family
Element 3 lithium has one valence electron and element 4 beryllium has two valence electrons Element 5 boron has how many valence electrons?
Boron has 3 valence electrons.Boron has 3 valence electrons.
Are all elements with one valence electron conductive?
No. For example, Hydrogen is an element with one valence electron, but it is a non-conductive gas under standard conditions.
If an element has 1 valence electron what group is it in?
That element would be in the Alkali Metals (group one)
