A period is a row in the Periodic Table which runs horizontally. Each atom in a period has one more electron than the previous atom. Periods feature atoms with similar principle quantum numbers. Within a period, the s and p orbitals have the same quantum number, and, if they exist in that period, the d orbital features a principle quantum number that is one lower than s and p, while that for f is two lower than s and p. Trends across a period include increasing electronegativity, decreasing atomic radius, increasing ionization energy, and increasing electron affinity.

How do periodic trends illustrate and change in chemistry?
Periodic trends illustrate how some elements are very reactive while others are stable.
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.
The periodic table is called periodic because the?
in 1869 periodic trends in the properties of the then-known elements
How do one recognize a periodic trend on the periodic table?
Studying physical and chemical properties of chemical elements it is possible to recognize some trends in the periodic table.
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 trends were seen in Mendeleev's periodic table?
he arranged his Periodic Table by each elements Atomic Mass
Why do we need to study the arrangement and trends of elements in the periodic table?
It is easier to study the properties of elements if they are arranged properly.
Who wrote the periodic table and what was it?
A Russian chemist named Dmitri Mendeleev wrote it and this periodic table was a table to illustrate recurring trends in the properties of elements.
Are the elements on the periodic table alike in properties?
Elements which are close together are generally likely to have similar trends, however, there are occasional blips of trend breakers.
How was the person who devised the first periodic table able to predict the behavior of elements such as gallium scandium and germanium that had not even been discovered yet?
The reason the periodic table was created in the first place was to illustrate the "periodic" physical properties of the known elements of the time. Because of this, the properties of elements that were "missing" from the table could be extrapolated from the periodic trends seen in the known elements.
How many elements are you periodic table?
118 elements are in the periodic table of elements; some of them are still unnamed (January 2013).
What are the columns on the periodic table called?
http://en.wikipedia.org/wiki/Periodic_tablegroups or families are verticalA period is a horizontal row in the periodic table. Although groups are the most common way of classifying elements, there are some regions of the periodic table where the horizontal trends and similarities in properties are more significant than vertical group trends.
