What change takes place as you move down in group 17 of periodic table in electron gain enthalpy?

on moving down the group the atomic size as well as nuclear charge inreases.But the effect of increase in atomic size is much more pronounced than that of nuclear charge and thus the additional electrons feels less attraction consequently electron gain enthalpy becomes less negative on going down the group

What is the number of valence electron for all the elements in periodic table group 1A 1?
One valence electron.
What do period members have in common in the periodic table?
There are seven periods in the periodic table--represented by seven horizontal groups. Each group is organized in such a way that is meant to illustrate similar chemical behavior in the elements. For instance, period 2 elements obey the ocet rule, which means that they need 8 electrons to complete (or stabilize) their valance shell.
Which family is group one in the periodic table?
The group-1 family is alkali metals. It has one valence electron.
What group in the periodic tables needs the least energy to lose one electron?
the alkali metals
What are the GROUP1 characteristics of the periodic table?
Group-1 are alkali elements.They have one valence electron.
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.
Which group on the periodic table will gain an electron in reaction?
group 17 - the halogens
Which group in the periodic table loss electron?
Alkali metals, Ist group.
What group in the periodic table gains electrons most readily and why?
Group-17 in the periodic table gains electron most readily. The elements in this group require only one electron to complete its octet.
How does the ionisation energy change down the groups in the periodic table?
Ionisation energy decreases down the group. It is easy to remove an electron.
What is group one on the periodic table?
group #1 on the periodic table is called alkali metals, has one valence electron, and is the most active metal group.
What group of the periodic table most readily accepts electron?
Group VII A or XVII or Halogens.
What is group in periodic table?
In the periodic table, group indicates the number of valence electrons in the outermost shell. E.g. Group I- the elements in that group have one valence electron in the outermost shell.
Why are elements in group one of the periodic table cations?
The elements of group 1 has 1 valence electron. They lose 1 electron to form cation.
What is the number of valence electron for all the elements in periodic table group 1A 1?
One valence electron.
What do period members have in common in the periodic table?
There are seven periods in the periodic table--represented by seven horizontal groups. Each group is organized in such a way that is meant to illustrate similar chemical behavior in the elements. For instance, period 2 elements obey the ocet rule, which means that they need 8 electrons to complete (or stabilize) their valance shell.
What is the location of elements that has only one valence electron?
Group 1: the group on the far left of the periodic table.
