The trend for the valence electron(s) is mostly significant to the the elements in s and p blocks. In other words groups 1-2 and 13-18 in the modern Periodic Table. The first four aforementioned groups have 1, 2, 3 and 4 electrons which can be shared with an other atom. The elements in groups 15, 16 and 17 are tend to obtain electrons from other elements 3, 2 and 1 respectively. The group 18 elements are naturally inert because they do not have valence electrons.

What is the valency of tin in the periodic table?
The valency of tin is variable. It can either be 2 or 4.
How do periodic trends affect bonding?
Periodic trends affect bonding due to the arrangement of the elements on the periodic table. The periodic table only includes chemical elements.

What do the elements in a column on the periodic table hav in common?
They have the same Valency
How do you do valency of an atoms?
You will have to check the valency from a periodic table. It will be written on the top right hand corner. e.g., O2
Are lithium and sodium a periodic table?
No sodium and lithium are in the periodic table they are both in the first column and are metals. They both have a valency 1
What valency is iron on the periodic table?

What did organizing information on the periodic table reveal?
Periodic patterns and trends
The periodic table is called periodic because the?
in 1869 periodic trends in the properties of the then-known elements
How are the trends in the periodic table helpful in identifying an element?
The periodic trends that arise from the arrangement of the periodic table provide chemists with an invaluable tool to quickly predict an element's properties. These trends exist because of the similar atomic structure of the elements within their respective group families or period and the periodic nature of the elements.
What is the valency of first and second group elements in the periodic table?
1 and 2 respectively
