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.
Why don't elements in group 8 bond with other elements?
The elements in group 8 of the periodic table are iron (Fe), ruthenium(Ru), osmium(Os), and hassium(Hs). All four of these elements are grouped together because each of their atoms has a full valence shell containing the maximum of 8 electrons. Atoms seek to bond when their outer valance is unstable and has less than 8 electrons. Their goal is to fill the valance with 8 electrons to become chemically unable to bond or "chemically inert." That is the case with the group 8 elements. They have a complete or closed shell and that is why they do not bond with other elements.
How many valence electrons does an atom have from group 16?
Atoms of elements in Groups 13-18 have 10 fewer valence electrons than their groups numbers.However , helium atoms have only 2 valence electrons.
Why is Chlorine in group 7 and period 3 of the periodic table?
That is where chlorine belongs (it is a noble gas). Chlorine has properties similar to the elements around it, and it has 7 valance electrons like the rest of the elements in its group.

What do valance electrons tell us about atoms?
they tell us if the substance is stable or not
How atoms in a group are similar?
Groups, in the periodic table of elements, are elements that all have the same number of valance electrons, which in turn tells us a lot about the kinds of chemical reactions that these elements will or will not undergo.
What does groups in a periodic table have?
atoms in a group have the same number of valence electrons
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.
How many valance electrons does the carbon group have?
4
Which group 0 2 5 or 7 atoms electronic configuration 3s2 3p5?
Looks like seven valance electrons to me. that would make this group the halogens, 7A.
How many valence electrons does a fluorine atom contain?
A fluorine atom has 7 valance electrons. This can be identified by looking which group fluorine is located, which is group 7. However when the atoms get bigger this rule does not apply so easily.

What groups of atoms give off the most energy when they gain electrons?
Group 17, halogens
Does group 1 give or take valance electrons?
give
Radium is in group 2 of the periodic table what does group mean?
This group, as all groups, shares similar interaction dynamics with other elements because this group, group 2A, has two valance electrons in the outer shell.
