What is the relationship between the group and the number of valence electrons in periodic table?

They are the same! Elements in group IA (alkali metals) have 1 valence electrons. Elements in group IIA (alkaline earth metals) have 2 valence electrons. Group IIIA (boron family) has 3 valence electrons, and so on.

∙ 9y agoIf you are just looking at the main group elements, the group number would correspond perfectly to the number of valence electrons. However, upon including the other groups, the relation is. S-block: valence e- = group number. P-block: valence e- = group number - 10. D-block: valence e- = group number.

∙ 13y agoIn the modern Periodic Table with 18 columns, excluding helium, the number of valence electrons is the same as the column number for columns to the left of the transition elements and is equal to (the column number - 10) for columns to the right of the transition elements. The number of valence electrons in the columns of transition elements are not so simply correlated.

Second of all, the relationship between them is that they both are classified by atomic number, atomic radius, atomic structure, and the total number of protons, neutrons, and electrons (, which, by the way, makes a stable charge and stable isotope if the amount of each type of particle is equal).

∙ 14y agoThere is no relationship between this, however most of the elements in a group have the same number of valence electrons.

What has 7 valence electrons in the periodic table?
halogens
How do you work out the number of valence electrons in a substance?
Just get to know the periodic table of the elements; that is the key to understanding valence electrons.
How many valence electrons does Xenon have?
The number of Valence Electrons of Xenon is 8 because it is in the eighth group on the periodic table
In an periodic table dots around an elements symbol indicate the number of valence electrons in an atom?
yes, the number of dots represent the number of valence electrons in the periodic table.
How would you find valence electrons in a periodic table?
the group number of the periodic table shows the valence electron. such as :- sodium is placed in group 1 and have valence electron.
What is the relationship between two elements located in the same column on the periodic table?
They have the same number of valence electrons (electrons in their outermost shell). They do not have the same number of shells however.
What is the relationship between column numbers and number of valence electrons?
theses are not called colmns but are called groups of periodic table.the relation between them is that in the periodic table the elements are placed in such a way that the the number of electrons in the outermost shell are equal to the group number.
What are electrons in the outer unfilled energy levels called?
Valence electrons
How many valence electrons consult of the periodic table chorine?
Two valence electrons
Which side of the periodic table do elements gain valence electrons?
all the elemants have valence electrons the last number of the elecotrons is the elemets valence electrons
Which group of elements 7 valence electrons?
The groups of electrons with 7 valence electrons are groups 7 and 17 on the periodic table.
How many valence electrons dose As from the periodic table have?
As is present in group-15. It has 5 valence electrons.
How many valence electrons does AsO2 have?
As,Arsenic belongs to nitrogen family in periodic table so it has 5 valence electrons.
What has 7 valence electrons in the periodic table?
halogens
Does the valence electrons equal the number of protons?
Rarely. The number of valence electrons of an element depends on it's position on the periodic table. Any given element can have between 1-8 valence electrons. The number of valence electrons increases left to right on the periodic table, while the number of protons, which determine the atomic mass and identity of an element, increase in general. Therefore the number of valence electrons can only equal the number of protons at the 8th element and below (neon).
What happened to the number of valance electrons move from left to right on the periodic table?
the number of valence electrons increases on moving from left to right in periodic table.Group 1 has 1 valence electron and group-18 has 8 valence electrons.
What relationship is there between the outermost suborbital in an atom and its position in the periodic table?
The position in the periodic table can range in size moving from left to right, and it has a wider range of numbers, but in the outermost suborbital, it can only range from 1-8 valence electrons!
