Elements are separated into groups with similar chemical properties. If you organize the elements in order of increasing atomic number, certain repititions occur, which makes it handy to predict how different elements in the same group will react. For example, oxygen and sulfur bear very little resemblance to each other; one's a colorless gas and the other's a non-metal solid. However, in a chemical reaction, they react very similarly, which is why they are placed in the same group.
It means that elements can be separated by their chemical simulatries as they are on the periodic table of elements.
There are 18 groups and 7 periods in the modern periodic table.
Sounds like the Periodic Table of the elements.
Groups in the periodic table are the vertical columns in which the elements are arranged.
The elements with similar properties are placed in groups. Periodic table contain 18 groups.
