distinguish between the terms group and period
Question
distinguish between the terms group and period
Solution
In the context of the periodic table in chemistry:
-
Group: A group in the periodic table refers to the vertical columns. Elements in the same group share similar chemical properties because they have the same number of valence electrons in their outer shell. For example, all elements in Group 1 (except hydrogen) are alkali metals, and they are highly reactive due to having one electron in their outer shell.
-
Period: A period in the periodic table refers to the horizontal rows. Elements in the same period have the same number of atomic orbitals. For example, all elements in the second period have two atomic orbitals. As you move from left to right across a period, each element has one more proton in its nucleus and one more electron in its outer shell compared to the element before it. This affects the element's chemical properties, making elements in the same period have different properties.
