describe the general trend in size going from top to bottom of any group or family
Chemical families are also known as the columns on the periodic tables. The general trend is that the amount of energy required to lose an electron decreases as you move down a column, or chemical family.
what does a group/family have of elements have in common
decreases from top to bottom
Within a row, as you move from left to right, the trend is typically an increase in density due to the increase in atomic number. Within a group, as you move down, the trend is typically an increase in density due to the increase in atomic mass and the addition of more electron shells.
Electronegativity decrease down in a group.
I suppose that this trend is normal.

Electronegativity decrease down in a group.
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.
As you move down a family on the periodic table, the mass of the atoms generally increases. This is because each element in a family adds an additional energy level or shell of electrons, which adds to the overall mass of the atom.
In the group 2 (IUPAC name) of the periodic table the atomic radius increase from beryllium to radium.
going down a group, electronegativity decreases going across a period, electronegativity increases
When moving across a period from left to right on the periodic table, properties tend to increase up to group 14 and then decrease. Within a group, as you move down, the properties generally increase due to the addition of extra electron shells.
