What do the groups of the periodic table tell us?
The group number tells you the total number of electrons present in the outermost orbit of an atom. In other words, group number tells you the number of valence electrons of an atom. For example, Let us consider group 1 of the Periodic table. Group 1 indicates that the elements lying in that group have only 1 electron in its outermost orbit.

Why are elements in Groups 13-16 categorised together?
Groups 13-16 don’t really fit together in any nice way, so let’s look at them one by one. The thing they have in common is the progressive filling of a p-orbital. The metallic properties of these elements decrease along each period and increase down each group. As a result, these groups contain non-metals like nitrogen, oxygen and sulfur, all the semimetals, and metals like aluminium, tin, lead, and bismuth.
Why is polonium used as a radiation source?
Polonium has been used as a radiation source, and due to its high radioactivity, in thermoelectric generators.
What is nitrogen gas?
Ammonia, nitric acid and nitrate salts were known, in some cases, since ancient times. Even though 78% of the Earth’s atmosphere is nitrogen gas, it was only discovered in 1772 by Daniel Rutherford who called it noxious air. Rutherford did not identify it as an element and several other contemporary scientists also investigated it and proposed the names burnt air and phlogisticated air. Antoine Lavoisier proposed the name azote from Greek meaning no life, as animals and flames died in pure nitrogen, and whilst this was adopted in other languages, only the chemical term azo- was adopted in English, as did the name pnictogen (Greek for producing suffocation) for the group to which nitrogen belongs. In 1790, Jean-Antoine Chaptal proposed the name nitrogene from nitre, the French name for potassium nitrate, and Greek -gene meaning to produce. The association was that nitre was used to make an acid (nitric acid) of which nitrogen was a key element.
What is the most common metal in the Earth's crust?
Aluminium is the most common metal in the Earth’s crust and found in over 270 minerals, though not in pure form owing to its high reactivity. The mineral alum (containing aluminum and sulfate) was used since 5th century BC Greece in the dyeing of fabrics and continued to be of commercial importance into the 16th century. Various scientists proposed that alum was the salt of a new element, and Hans Christian Ørsted first isolated the metal in 1824. Aluminum remained scarce and more expensive than gold until modern methods of extracting it from the minerals bauxite and alumina (aluminium hydroxide and oxide) were developed in the late 1800s.
Why is lead being phased out?
More recently lead has been used for ammunition, ballasts, construction, radiation shielding, lead glass and lead-acid batteries, however it has been phased out of many applications due to its toxicity.

What is the oxygen group on the periodic table?
Oxygen group is the group 16 on the periodic table.
What is an example of group 18?
Example of group 18. All the elements of group 18 are chemically inert (that means they do not easily react with other elements). And all the elements of group 18 have a complete octet (that means they have 8 electrons in their outer shell).
