The groups in the Periodic Table that have different numbers of valence electrons are the main group elements (Groups 1, 2, and 13-18). For example, Group 1 elements have one valence electron, while Group 2 elements have two. Transition metals (Groups 3-12) also display variability in their valence electron counts due to their d-orbital involvement, leading to a wider range of oxidation states. Each group’s distinct number of valence electrons determines its chemical properties and reactivity.

How can the number of core electrons be detemined from the periodic table?
Take carbon as an example.Carbon, indicated by it's atomic number, has 6 electrons. The number at the top of carbon's group is the number of valance electrons. Carbon has 4 valance elections.6 total electrons - 4 valance electrons= 2 core electrons in carbon=====================(try another element yourself to see this process )
What elements have the same number of valance electrons as boron?
All in the same group: 13 (or 3) like Al, Ga, In.
What is the number of valance electrons as you move right across a row or period in the periodic teale?
It depends on which group you are talking about. The number of valance electron normally increase by one as you move right across the table. when you get to the transition metals however, the valance electron will vary.
What are the columns used for on the periodic table?
the elements in a given column (or group) have the same number of valence electrons and hence similar chemical properties.
How many electrons are in oxygen's outer level?
The word "valance" is used to describe electrons in the outer-most energy level of an atom. Oxygen has six valance electrons.
How can the number of valence electrons be determined from the periodic table?
By looking at the group number you can tell how many valance electrons there are ex: Group 1= 1 valance electrons Group 2-12= 2 valance electrons Group 13= 3 valance electrons Group 14= 4 valance electrons Group 15= 5 valance electrons Group 16= 6 valance electrons Group 17= 7 valance electrons Group 18= 8 valance electrons
How many Valance electrons in oxygen?
6 Use the periodic table as a guide. As you go across from left to right the number of valence electrons increases. H = 1 Be = 2 B = 3 C = 4 N = 5 O = 6 F = 7 This trend stays the same all the way down each column. Usually periodic tables are marked on the top with roman numerals or something to signify how many valence electrons each element has.
How can the number of core electrons be detemined from the periodic table?
Take carbon as an example.Carbon, indicated by it's atomic number, has 6 electrons. The number at the top of carbon's group is the number of valance electrons. Carbon has 4 valance elections.6 total electrons - 4 valance electrons= 2 core electrons in carbon=====================(try another element yourself to see this process )
Why noble gases require the group 8 in the periodic table?
They have a perfect octet of valance electrons; eight in number.
How many valance electron does krypton have?
Since krypton is a noble gas in the group number 18, it has 8 valence electrons. Eight is the maximum number of valence electrons.
Does group 1 give or take valance electrons?
give
What has 5 electrons in its outer shell?
If you are talking about the valance electrons any elements in group 5 on the periodic table will have 5 valance electrons.
What is the group number for elements that have a stable number of electrons in their energy levels?
They r noble gases which have stable valance shell and grotp no. 18
Which group of elements forms bonds by using their six valance electrons?
Group 16 because on the periodic table, there are different columns that represent a greater or lesser amount of valence electrons; and group 16 has the amount of 6 valence electrons.
What elements have the same number of valance electrons as boron?
All in the same group: 13 (or 3) like Al, Ga, In.
What is the number of valance electrons as you move right across a row or period in the periodic teale?
It depends on which group you are talking about. The number of valance electron normally increase by one as you move right across the table. when you get to the transition metals however, the valance electron will vary.
How many valance electrons does halogen have?
Halogens are group 17 elements. They have 7 valence electrons.
