In Group 1 of the Periodic Table, the elements have one valence electron. As you move down the group, the size of the atoms increases due to the addition of more energy levels. As a result, the outermost electron becomes further away from the positively charged nucleus and more shielded by inner electrons. Thus, the electronic structure remains similar, with one valence electron, but the atoms become larger in size.

Why are Group 1 and Group 2 elements found in many compounds but not Group 18 elements?
group 18 has completely filled electronic configuration and hence are stable. group 1 and group 2 have 1 and 2 electrons respectively in their valence shells and needs to lose these to attain completely filled electronic configuration. hence they are reactive.
Why is the noble gases a group of un-relative elements?
because they have completely filled electronic configuration.
Why do neon and helium have different number of dot in their Lewis structures if they are in the same group?
because they are different types of elements.
What elements on the periodic table have the highest energies?
Group 18 as they have completely filled electronic configurations, are stable and hence do not ionize.
What elements in the same group and family have?
in the same group( family) have the same electronic configurationhttp://en.wikipedia.org/wiki/Group_(periodic_table)
What group is ns2np4?
Group 6A Elements (ns2np4, n ≥ 2).
Why is hydrogen grouped with elements in group 1a?
valence electrons and electronic configuration.
What is the electronic structure of group 1 elements?
An outer electron shell with only one electron.
Why are Group 1 and Group 2 elements found in many compounds but not Group 18 elements?
group 18 has completely filled electronic configuration and hence are stable. group 1 and group 2 have 1 and 2 electrons respectively in their valence shells and needs to lose these to attain completely filled electronic configuration. hence they are reactive.
Mention the General electronic configuration of nitrogen group elements?
these elements have 5 electron in the valence shells and have configuration of ns np5
Which data structures is a group of data elements that usually describes a single entity or event?
record
What is distinctive about the electronic configuration of the group 2 elements?
They all have 2 electrons in their outer shells.
Why is the noble gases a group of un-relative elements?
because they have completely filled electronic configuration.
Why the elements in group 3A and 6A dips in ionization energy?
Beacause of electronic configuration (M.O.T)
Why size of 18th group elements is larger?
This is because, 1) Inter electronic repulsions between electron pairs present in the outermost orbit. 2) In 18th group elements vanderwaal's radius is considered.
What elements lack a noble gas electron configuration?
Only group 18 elements have noble gas configuration. All other elements lack a noble gas electronic configuration.
Why do neon and helium have different number of dot in their Lewis structures if they are in the same group?
because they are different types of elements.
