3. What happens to the size of atoms in p-block elements when we move from left to right in the same period? a) Size does not change b) Size increases then decreases c) Size increases d) Size decreases
Answer: d Explanation: The size of the atoms of the elements decreases from left to right throughout the same time period. The electrons are added to the same shell because the row is the same. On the other side, an increase in atomic number corresponds to an increase in protons, or positive charge. The overall effective nuclear charge rises as a result. As a result, the electron cloud is drawn closer to the nucleus of the atom. As a result, the size of the object decreases.
