Flashcards in Topic 1 - Group 1, Group 7 and Group 0 Deck (12):
1

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.

2

What is another name for Group 0 elements?

Noble gases.

3

Why is Group 0 unreactive?

They have full outer shells.

4

What is another name for Group 1 metals?

Alkali metals.

5

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.

6

Why does reactivity increase as you go down the group?

The outer electron is more easily lost since it is further from the nucleus.

7

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

8

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.

9

What is another name for Group 7 elements?

The Halogens

10

What are the trends as you go down for Group 7?

Less reactivity, higher melting/boiling points, higher atomic masses.

11

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.

12

What kind of bond does Group 7 form with metals?

Ionic
