due to which the outermost electrons will be far away from the nucleus and consequently, the effective nuclear charge is less. secondly, the shielding effect also increases down the group with the increasing number of shells, which in turn results in the decreasing ionisation energy. electron gain...

The periodic trend in atomic radius depends on two factors: (1) principal quantum number and (2) effective nuclear charge. These two factors contrarily affect the atomic radius.Answer and Explanation: In the periodic table, the principal quantum number predominantly controls the ...

In general, chemists and other scientists can use the table to predict how certain elements will react with one another. The alkali metals, for instance, are in the first column or group of the table and tend to have one valence electron and so carry a charge of +1. This charge means ...
