Helium, Neon, and Argon in Group 18 are inert gases. 8 Periods Reflects a filling of electron shells. Elements in period 4 fill the fourth electron shell. 7 Groups Vertical columns on the periodic table. The transition metals are found in groups 3 through 12. 8 Periods Properties change ac...
Most of the elements on the period table of elements are classified as metals. The periodic table of elements groups the elements into different families based on their characteristics. There are several different families of elements that qualify as metals. ...

'Periods' are the horizontal rows that run from left to right, while 'groups' are the vertical columns (going from up to down). Different groups are present in the periodic table: The Alkali Metals The Alkaline Earth Metals The Transition Metals ...
The columns of the periodic table are called groups. All elements in a group share the same number of valence electrons. The three broad categories of elements are metals, nonmetals, and metalloids. Most elements are metals. Nonmetals are located on the righthand side of the periodic table....
The red column is known as Group 1, and the orange column is Group 2. The elements in these groups are known as reactive metals. Pure sodium fizzes and shoots around when placed in water, potassium bursts into flame in water and caesium explodes when added to water! The reactivity of the...
Any element in the d-block of the periodic table, which encompasses groups 3 to 12, is referred to as a "transition metal" by many scientists. The f-block lanthanide and actinide series are also considered transition metals and are referred to as "inner transi...
If you don't have the chart of the activity series handy, you can also use trends in the periodic table to predict the reactivity of a metal or nonmetal. The most reactive metals belong to thealkali metalselement group. Reactivity increases as you move down the alkali metals group. ...
