Which group on the periodic table is correctly paired with its description?
A
Group 1: Alkali metals, highly reactive with water
B
Group 18: Halogens, form salts with metals
C
Group 17: Transition metals, good conductors of electricity
D
Group 2: Noble gases, inert and non-reactive
Verified step by step guidance1
Begin by identifying the groups on the periodic table. The periodic table is organized into columns called groups, each with distinct chemical properties.
Group 1 consists of Alkali metals. These elements are highly reactive, especially with water, and include lithium (Li), sodium (Na), and potassium (K).
Group 18 contains Noble gases. These elements are known for being inert and non-reactive due to their complete valence electron shells, including helium (He), neon (Ne), and argon (Ar).
Group 17 is made up of Halogens. These elements are highly reactive and tend to form salts when combined with metals, such as chlorine (Cl), bromine (Br), and iodine (I).
Group 2 consists of Alkaline earth metals. These elements are somewhat reactive and include beryllium (Be), magnesium (Mg), and calcium (Ca). Transition metals, which are good conductors of electricity, are found in groups 3-12.
