How do the atomic size and metallic character of elements vary as we move: (a) down a group and (b) from left to right in a period Q.(a) What is a group in the periodic table? In which part of a group would you separately expect the elements to have (i) the gr...
To determine which group in the periodic table contains elements in all three physical states (solid, liquid, and gas) at room temperature, we can analyze each group provided in the options. 1. Identify the Groups: We have four groups to consider: - Group 5A (Nitrogen family) - Group ...
Groups and periods are two ways of categorizing elements in the periodic table. Periods are horizontal rows (across) the periodic table, while groups are vertical columns (down) the table. Atomic number increases as you move down a group or across a period. Element Groups Elements in a group...

The group number is an identifier used to describe the column of the standard periodic table in which the element appears. Groups 1-2 termed s-block elements. Groups 1-2 (except hydrogen) and 13-18 are termed main group elements.
