What is the significance of the periodic table of elements?

To summarize, the periodic table is important because it is organized to provide a great deal of information about elements and how they relate to one another in one easy-to-use reference. The table can be used to predict the properties of elements, even those that have not yet been discovered.

What was special about the arrangement of his table?

In 1865, the English chemist John Newlands arranged the known elements according to their properties and in order of increasing atomic mass. He placed the elements in a table. As he studied his arrangement, Newlands noticed that all of the elements in a given row had similar chemical and physical properties.

What is significant about the elements within the same group of the periodic table?

The periodic table of the elements places the elements according to their atomic number, electronic configuration and chemical properties. Thus, depending on the location of an element in the periodic table, we can guess its electronic configuration and more importantly, its properties.

What information can you tell about an element based on its position in the periodic table?

Elements are placed in order on the periodic table based on their atomic number, how many protons they have. In a neutral atom, the number of electrons will equal the number of protons, so we can easily determine electron number from atomic number.

How can we use the periodic table to predict reactivity?

The number of electrons in the outermost shell of an atom determines its reactivity. Noble gases have low reactivity because they have full electron shells.
