Across chemical groups, elements are generally organized according to their chemical mass with the execption of a couple spots. If you study the Periodic Table of elements than the first trend you would notice is that the atomic number rises by one each time. Down periods, trends occur such as elements in a colmn are organized by their properties.

Does an element on the periodic table decrease in atomic size when you move across a period from left to right and when you move down a group?
1. In a period is a trend of decrease from left to right but it is not absolute.2. In a group the atomic radius increase moving down.
What is the trend in density as you go down the group of halogens?
The density increase down.
Which trend decreases for metals down a group?
Melting Point
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 trend can be observed among the atomic radii of main-group elements down a group?
Within a group, the number of shells (or energy level) increases (as we go from top to bottom of a group) and hence the size of the atom or the atomic radii increases.
What is group trend of boiling point in IA group?
The boiling point decrease from lithium to caesium.

The trend in the atomic radii as you move down the group 1A elements is partially due to what?
Adding more electrons that need to occupy higher energy orbitals
What do you predict the trend in atomic mass will be going down a group?
The atomic mass increases down a group.
What is the trend in density as you go down the group of halogens?
The density increase down.
Which trend decreases for metals down a group?
Melting Point
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 group trend in p-block element?
Atomic radius increases down the group
What trend is oberserved among the atomic radii of main-group elements down a group. eplain this trend?
The trend of atomic radius increases down a group on the periodic table. This occurs because each successive element down a group has another energy level. As more electrons are added, more energy levels are needed to hold the electrons.
What is the trend for atomic mass?
It increases as you move to the right or go down
What trend can be observed among the atomic radii of main-group elements down a group?
Within a group, the number of shells (or energy level) increases (as we go from top to bottom of a group) and hence the size of the atom or the atomic radii increases.
