One reason the periodic table of the elements is so useful is that it is a means of arranging elements according to their similar properties. This is what is meant by periodicity orperiodic table trends. There are multiple ways of grouping the elements, but they are commonly divided into met...
Periodic Table of the Elements Introduction to the Periodic Table People have known about elements like carbon and gold since ancient time. The elements couldn't be changed using any chemical method. Each element has a unique number of protons. If you examine samples of iron and silver, you ...
The elements can also be classified into themain-group elements(orrepresentative elements) in the columns labeled 1, 2, and 13–18; thetransition metalsin the columns labeled 3–12; andinner transition metalsin the two rows at the bottom of the table (the top-row elements are calledlanthanid...

metals. Specifically, they are a collection of transition metals that are calledthe lanthanides and actinidesor the rare earth metals. These elements are located below the table because there wasn't a practical way to insert them into the transition metal section without making the table look ...
Electron Affinity - the amount of energy released when an electron is added to a neutral atom or molecule to form a negative ion. Melting/Boiling Point Highest in the middle of a period. The elements get more metallic as you go down the table, and less metallic as you go across....
