firstly boron due to its small size has highest electronegativity in the group.Next Al , has larger size and atomic radii so electronegativity decreases.
But in Ga due to the presence of 10 d-electrons , the shielding effect gets reduced.
As a result the attraction due to the nuclear charge increases.
The same happens with In and Tl.

What is the trend in electronegativity of elements when going down the group?
Electronegativity increases as you go along a group/family Everything about elements increases as you go farther down and to the right of the periodic table except the radius, in which the largest elements are at the bottom left, and the smallest at the top right
Why acidic character of oxides of group 15 elements decreases down the group?
The acidic character of oxides of group 15 elements decreases down the group because as we move down the group from nitrogen to bismuth, the ability of the oxide to donate protons decreases due to an increase in atomic size and metallic character, which results in a weaker acidity. Additionally, the anionic character of the oxide decreases as the metallicity of the element increases, leading to a less acidic nature of the oxides down the group.
Which family does NOT have electronegativity values?
It is not true to say that any family does not have electronegativity values. It is tempting to say the inert gases, group 18, but we have a value for the electronegativity of xenon, 2.6 on the Pauling scale. Some of the other members of the group form compounds, though they are difficult or impossible to isolate, and their electronegativities have therefore not been measured. Whether they can thus be said to have electronegativity values or not is a moot point.
What happens to the energy needed to remove an electron as the atomic number increases down a family?
As the atomic number increases down a family, the energy needed to remove an electron decreases. This is because electrons are further from the nucleus with increasing atomic number, leading to weaker attraction and therefore less energy required to remove an electron.
What is the trend for ionic radius for medals?
The trend for ionic radius across the metals is that as you move down a group on the periodic table, the ionic radius increases. This is because as you go down a group, the number of electron shells increases, leading to larger atomic size and hence larger ionic radius.

Why does electronegative decrease down a family?
As we move down a family,although nuclear charge(proton number)increases,the number of shells increases.This make the outermost electrons far away from nucleus and electrons feel less attracted to the nucleus.SO electron negativity decreases.It is opposite to first ionization energy where it is easier to ionize electrons as we move down a family.On the contrary,it is difficult to attract electrons.
What patterns are observed left to right across a periodic table?
The electron pattern is the same among elements in a family. This is the reason the periodic table is arranged as it is.
Are coffee leaves arranged alternately?
No, opposite. Family Rubiaceae.
What trend in electronegativity do you see as you go down a group-family on the periodic table?
Electronegativity decrease down in a group.

What is the relevance between birth rate and gnp growth rate?
There would be a negative relationship, because as GNP increases in a country there is a higher investment in terms of education and family planning, which is a factor that decreases birth rates in a country.
What is the family name for Chlorine in the periodic table of elements?
Chlorine belongs to the family of halogens.It has electronegativity of 3.16.It has atomic number 17.
What is the most active metal on the periodic?
Francium is the most reactive metal. Reactivity increases and you go down a family and decreases as you go across a period on the Periodic Table. Francium is the farthest left and the lowest so it is the most reactive.
What type of doctor treats strep throat?
Your family physician will treat the sore throat. Alternately the ENT specialist will treat you.
