What is the general trend of electro negativity as you go down the periodic table?
The electronegravity decreases as you go down the periodic table. As you go down the columns in the periodic table the atoms get bigger because there are more full shells of electrons (although the number electrons in the OUTER shell always stays the same for each element in the group). so because there are more shells the outer shell of electrons becomes increasingly further away from the nucleus this means they are shielded from the attractions of the positive nucleus' pull by the increasing number of inner shells.
hope this was the answer you were looking for and that it made sense.

What element has the lowest electronectivity?
Francuim is thought to have the lowest electro-negativity.Linus Pauling estimated that francium had the same electro-negativity as Caesium = 0.7. The electro-negativity of caesium was later revised to 7.9 but francium is so unstable and reactive that it is not possible to obtain samples of pure francium to accurately determine its electro-negativity.
Does chlorine have the highest electronegativity?
Yes chlorine does have highest electro-negativity due to its highest electron gain enthalpy
What trend does electro negativity follow going down the periodic table?
Electronegativity decreases as you go down a group in the periodic table. This is because as you move down a group, the atomic radius increases, leading to a decrease in the attraction between the nucleus and the outer electrons, resulting in lower electronegativity values.
What can be deduced about the electronegativity of hydrogen relative to that of nitrogen?
The electro negativity of Nitrogen is 3.04 and the electro negativity of Hydrogen is 2.10. If you subtract the two numbers, you will have the electro negativity difference.Eg3.04 - 2.10= 0.94This works for all of the elements on the periodic table the same way.
What is the general trend of the melting points of elements on the periodic table?
The general trend of melting points of elements on the periodic table increases from left to right across a period and decreases down a group.
Where is electronegativity lowest on the periodic table?
Electro negativity is lowest in the bottom of the first group. Cs and Fr have least electro negativity.
What elements has the highest electronagativity?
The element with the highest electro negativity is Fluorine. The general trend on the periodic table for electro negativity is that as you go across periods (horizontally) the electro negativity increases while going down groups (vertically) the electro negativity decreases.
How does the electro negativity change as you move down a group in the periodic table?
As we move down a group, electronegativity decreases.

How can an element's properties on the periodic table be predicted?
an elements location on the periodic table tells almost the complete story of every element on the table... electro-negativity, atomic radius, electron affinity, # of electrons, protons, neutrons, atomic weight, and many chemical properties as well. Start by looking at the columns on the periodic table. The 1st column is alkali metals, and all those elements in that column share similar properties. The same is true for the second column, and the last few columns on the right side of the table. There are also "trends" on the table, such as one which says that as you move left to right, and top to bottom on the table the electro-negativity increases. Do some more research on the terms i listed in the first paragraph. Those are the keys to understanding how to predict an elements properties.
Why does electro negativity decrease while going down the periodic table?
Down the group the size of atom increases. Hence the force of attraction between the nucleus and the electrons of the next atom decreases. Or in other words, the electronegativity decreases down the group.
What trend does electro negativity follow going down the periodic table?
Electronegativity decreases as you go down a group in the periodic table. This is because as you move down a group, the atomic radius increases, leading to a decrease in the attraction between the nucleus and the outer electrons, resulting in lower electronegativity values.

What does the periodic table describe about an element?
Periodic table describes the symbol, atomic number, mass number of different elements in general.
