That varies, element #3 will have 3, element 4 will have 4, etc.
However, they all have 2 valence electrons.
The groups in the periodic table tell you what each element within them will react with, the number of valance electrons the element has, and what family it is in.
Any element in group 1
there are 6 valence electrons in each element in group 16
A group in Periodic Table is the column of element in periodic table
By the group number of the A columns
2 electrons.
-An element is placed in that group of periodic whose group number is equal to the number of valence electrons.
These are the alkali metals (group 1 of the periodic table).
In the Periodic Table of the Elements, a column (group) contains all elements that exist with the group number of electrons in the outer energy level of an atom of that element.
Fluorine is a nonmetal. It is located in group 17 of the periodic table. It tends to obtain an electron to form the fluoride ion.Fluorine is the element with highest electronegativity. So it does not tend to lose electrons. It is in the 17th group of the periodic table.
This depends upon The Periodic Table GROUP to which an element belongs to.
In the Periodic Table of the Elements, a column (group) contains all elements that exist with the group number of electrons in the outer energy level of an atom of that element.
