Question

match the description to the appropriate chemical family. alkali metals alkaline earth metals noble gases halogens transition metals makes up the d - block of the periodic table, these are used as catalysts for chemical reactions most reactive of all metals, chemical reaction with water is very violent and causes hydrogen gas to be released (which then ignites) most of this group is chemically inert, one element is known for use in bright sign tubing group name means \salt - forming\, includes the most electronegative element on the periodic table unique because they become more soluble as temperature decreases

Explanation:

1. Transition metals make up the d - block of the Periodic Table and are used as catalysts for chemical reactions.
2. Alkali metals are the most reactive of all metals, and their chemical reaction with water is very violent, releasing hydrogen gas which then ignites.
3. Noble gases are mostly chemically inert, and neon (a noble gas) is known for use in bright sign tubing.
4. Halogens' group name means "salt - forming", and fluorine, the most electronegative element on the periodic table, is a halogen.
5. The description about solubility with temperature change does not match the common properties of the given chemical families.

Answer:

1. transition metals - makes up the d - block of the Periodic Table, these are used as catalysts for chemical reactions
2. alkali metals - most reactive of all metals, chemical reaction with water is very violent and causes hydrogen gas to be released (which then ignites)
3. noble gases - most of this group is chemically inert, one element is known for use in bright sign tubing
4. halogens - group name means "salt - forming", includes the most electronegative element on the periodic table
5. No match - unique because they become more soluble as temperature decreases
