The 'Periodic Table' is characterized as the 'tabular representation of chemical elements as per their atomic number in order to keep the elements possessing similar properties in a single group.'
In case one moves towards right from left in this table except for the transition elements, the trend that occurs would be:
A). Valence electrons increase by one.
- 'Valence electrons' are described as 'any of the electrons that are present in an atom's outermost shell.'
- These are the electrons that possess the ability to develop bonds with other present atoms.
- The valence electrons present increase by one unit to maximum of 4 units in the period if we move from the left towards the right leading to an enhanced charge on the nucleus.
Thus, option A is the correct answer.
