Groups In The Periodic Table Flashcards
(8 cards)
What are the physical properties of Group 1 elements?
Group 1 elements are soft, have low melting and boiling points, and are good conductors of electricity.
How do Group 1 elements react with water?
They react vigorously, producing hydrogen gas and a hydroxide of the metal, forming an alkaline solution.
What is the trend in reactivity down Group 1?
Reactivity increases down the group due to the outer electron being further from the nucleus and more easily lost.
What are the physical states and colors of the halogens at room temperature?
Chlorine is a green gas, bromine is a red-brown liquid, and iodine is a grey solid.
What is the trend in reactivity down Group 7?
Reactivity decreases down the group as the outer shell is further from the nucleus, making it harder to gain an electron.
What happens in a displacement reaction involving halogens?
A more reactive halogen will displace a less reactive halogen from its compound.
What are the properties of noble gases?
They are colorless, odorless, inert gases with low boiling points that increase down the group.
Why are noble gases unreactive?
They have a full outer electron shell, making them stable and unlikely to react.
