Flashcards in Topic 1 - Group 1, Group 7 and Group 0 Deck (12):
Why does the boiling point increase as you go down Group 0?
The atoms are larger so the inter molecular forces are harder to break. They require more energy.
What is another name for Group 0 elements?
Why is Group 0 unreactive?
They have full outer shells.
What is another name for Group 1 metals?
How does Group 1 react with water? How does it vary throughout the group?
They produce a metal hydroxide and hydrogen. The amount of energy given out increases the further down the group you go.
Why does reactivity increase as you go down the group?
The outer electron is more easily lost since it is further from the nucleus.
How do Group 1 metals react with Chlorine? How does it vary throughout the group?
They react vigorously and form metal chloride salts. As you go down, it gets more vigorous
How do Group 1 metals react with Oxygen? How does it vary throughout the group?
They from a metal oxide. Lithium forms Lithium Oxide, Sodium forms Sodium Oxide and Sodium Peroxide, Potassium forms Potassium Peroxide and Potassium Superoxide.
What is another name for Group 7 elements?
What are the trends as you go down for Group 7?
Less reactivity, higher melting/boiling points, higher atomic masses.
Why is Group 7 less reactive as you go down?
It becomes harder to gain a new electron since the outer shell is so far from the nucleus.
