In 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.

∙ 7y agoTo be an element and have only one valence electron means having only one proton. If the number of protons and electrons are not matched you have an ion.
The only element with just one proton is Hydrogen.

What is the number of valence electrons for the elements in group 1?
The elements in Group 1 have one valence electron in their outermost s orbital.
Group 1a elements have how many electrons in their valence shells?
All these have one electron in their valence shell.
Why does a d-block have elements a variable valency?
because they have one valence electron
What is the electronic structure of group 1 elements?
An outer electron shell with only one electron.
What elements have 2 valence electron?
Zinc and Calcium
The elements in group 7A have one valence electron true or false?
A valence electron, or valence electrons, are found in all of the elements. A valence electron is an electron located on the out most shell of an element (the valence shell). Most elements will have more than one valence electron. Oxygen, or O, has six valence electrons because its outer shell consists of six electrons.
What is the number of valence electrons for the elements in group 1?
The elements in Group 1 have one valence electron in their outermost s orbital.
What is the number of valence electron for all the elements in periodic table group 1A 1?
One valence electron.
What has one valence electron and reacts with other elements?
Any element in column 1 of a wide form periodic table has exactly one valence electron and reacts with other elements.
What is the number of valence electrons in group one?
Valence electrons are the electrons in the furthest electron shell from the nucleus.For the first three rows, essentially, the number of valence electrons is the number of squares the element is away from the beginning of the row at the left.For example. Sodium is the first (group 1) it has 1 valence electron. Magnesium is the second, it has 2 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.
Group 1a elements have how many electrons in their valence shells?
All these have one electron in their valence shell.
Why does a d-block have elements a variable valency?
because they have one valence electron
Why does a d-block elements a variable valency?
because they have one valence electron
What is the electronic structure of group 1 elements?
An outer electron shell with only one electron.
Elements that have one valence electron?
Elements in Group 1. (eg. Hydrogen, Lithium, Sodium etc.)
Why are elements in group one of the periodic table cations?
The elements of group 1 has 1 valence electron. They lose 1 electron to form cation.
