As you move down the groups in the Periodic Table, the atomic size increases due to the addition of electron shells. This results in higher shielding effects, which reduce the effective nuclear charge experienced by outer electrons. Consequently, elements become more reactive, particularly in groups like the alkali metals and halogens. Additionally, properties such as melting and boiling points often change, typically decreasing for metals and increasing for nonmetals.
What else can I help you with?
Which choice has the element groups in the correct order from left to right on the periodic table Apex?
In the modern Periodic Table ;- #1 ; Groups are the columns down. #2 ; Periods are the lines across.
Which direction are families on the periodic table?
groups on the periodic table are the vertical coumns that go up and down. A period on the periodic table are the rows that go horizontal or across.
What trend is seen atom size going down the periodic table?
Excepting groups 5-12 of the periodic table.the atomic radius increase down in the group.
What are the horizontal collum called in the periodic table?
There seems to be a typo in your question. If you meant a "horizontal row" (left to right) of the periodic table, those are called periods. If you meant a "vertical column" (up and down) of the periodic table, those are called groups.
What are some good questions about the periodic table?
Some good questions about periodic table: where are metalloids placed? why group 18 elements are inactive? How many groups and periods are in periodic table? How reactivity changes across and down the group?
A chart that arranges all known elements into groups?
Is the Periodic Table. The columns down are the GROUPS The lines across are the PERIODS.
What are groups on the periodic table?
there are alot of groups in the periodic table. to many to mention but each element is grouped into is like chemicals generally down the periodic table. heres a link which will give you all the groups and there properties http://en.wikipedia.org/wiki/Group_%28periodic_table%29
How does reading across a period the periodic table compare with reading down a group of the table?
Periods (across the Periodic Table) have increasing Atomic Mass. Groups (down the table) have similar properties and reactive natures.

How are groups on a periodic table numberd?
From right to left (1- 18) on the periodic table. Instead of up and down (1-7) periods go vertically. (rows) groups go horizontally. (columns)
What trend is seen atom size going down the periodic table?
Excepting groups 5-12 of the periodic table.the atomic radius increase down in the group.

What do you notice about the number of orbitels as you move from down a family in the periodic table?
the number of orbitals increases by one for each period.
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.
How does one recognize a periodic trend on the periodic table?
one should look for predictable changes and patterns
