Why was the element hydrogen placed in group 1 of the periodic table?
Hydrogen has one valence electron.
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 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
What is the number of valence electrons the element hydrogen has?
One.Hydrogen has only 1 electron in total, and it is also a valence electron.
How many valence electron are in potassium?
Just 1 valence electron in K (number 19, period IV, group 1)(Its electron configuration is 4s1, in which 4:means shell number 4, s: means s-orbital, 1: means 1 electron)4s1your answer is 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.
Why was the element hydrogen placed in group 1 of the periodic table?
Hydrogen has one valence electron.
What is the element of group 1 in the periodic table is called?
Group-1 elements are called alkali metals. They have one valence electron.
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.
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 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
What is the valence electron configuration of each element in group 1?
All elements in group 1 have 1 valence electron.
How many valence electrons are contained in an atom of Rb?
1: This is the correct answer for any element in wide form Periodic Table Group 1.
What is the number of valence electrons the element hydrogen has?
One.Hydrogen has only 1 electron in total, and it is also a valence electron.
Which element has 1 valence electron and is in period 1.?
The element with 1 electron in period 1 would be hydrogen.
How can you determine the number of valence electrons in an atom?
You can determine how many valence electrons an atom has by what family the element of the atom is in. For instance, if the element is in family 8A, the number of valence electrons will be 8. Or, if the element is in family 2A, the number of valence electrons for the atom will be 2. So, whatever number family the atom is in, the number of valence electrons equals that.
How do you determine the number of valence electrons if you know the group no of elements?
valence electrons are electrons at the outermost shell as we all know, group in PE can be determined by looking at the valence electron thus if it is in group 1..then the valence electron is 1
