Text Solution

AI Generated Solution

**Step-by-Step Solution:** 1. **Understanding Atomic Size**: Atomic size refers to the distance from the nucleus to the outermost shell of electrons in an atom. 2. **Identifying the Trend in Groups**: In the periodic table, elements are arranged in groups (columns). As we move down a group, we need to consider what happens to the atomic structure. 3. **Increase in Atomic Number**: As we go down a group, the atomic number of the elements increases. This means that there are more protons in the nucleus. ...

The following questions refer to the Periodic Table : What happens to the atomic size of elements moving from top to bottom of a group.

Metals have few electrons in their valence shell while non-metals generally have more electrons in their valence shell. Metallic character is closely related to atomic radius and ionisation enthalpy. Metallic character increases from top to bottom in a group and decreases from let to right in a period of periodic table. metallic character is inversely related to electronegativity of element. Q. The electronegativity of the following elements increase in the order:
