What is the importance of valence electrons in the organization of the periodic table?

The importance of valence electrons is that atoms in the same group ("groups" in the Periodic Table are the vertical columns- for example, nickel and platinum are in the tenth column; therefore, in the same group). Atoms of elements in the same group have the same number of valence electrons, so they have similar properties. Hope that helped with your homework! ;D

∙ 13y agoValence electrons & electronic configuration are important for the periodic table because they help chemists to determine the properties of the elements &the type of chemical reactions that can be undergone by a particular element.

∙ 13y agoThe valence electrons are the electrons that can be involved in chemical bonding. With a knowledge of valence electrons the chemist can predict how an element is likely to react.

What is the most important factor determining how an atom will bond?
the oxidation number, determined by its group on the periodic table.
The nonreactive elements at the far right of the periodic table that contain an octet of electrons in their valence shell are?
D. Noble Gases
How many electrons of a calcium are involved in chemical bonding?
Calcium is in group II of the periodic table meaning that it has 2 valence electrons. These are the electrons that are involved in making a chemical bond, so the answer to your question is TWO.
What is the name of the electrons in the outermost level of an atom called?
The electrons in the outermost level are known as the valence electrons.
Which atoms are most reactive?
The most reactive elements have either 1 valence electron or 7 valence electrons
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
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 is the number of valence electrons in family 1A of the periodic table?
One valence electron.
How many valence electrons does group 1 in the periodic table have?
it has one valence electron
Valence electrons does Ba have?
Barium has two valence electrons, as can be deduced from its placement in Group 2 of the modern periodic table.
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.
