Flashcards in Ionic bonding Deck (13):
1

What happens to group one metals as you go down the group?

They get more reactive

2

What happens to the attractions of the outer electrons as you go down the group 1 elements?

The single outer electron is further from the positivley cahrged nucleus, accrodingly the bonds are weaker and less attracted

3

When drawing an Ion if the atom looses an electron(s) they have a square bracket with what sign?

+

4

When drawing an Ion if the atom gains an electron(s) they have a square bracket with what sign?

-

5

What do metals always do with electrons?

Loose them to gain a full outer shell

6

When drawing an ion what do you have to remeber to draw?

-Square bracket
-Charge

7

What is the trend in group 7 metals?

As you go down the group the elements become less reactive

8

Why are group 7 metals less reactive as you down the group?

The electron is further from the nucleus so is less attracted.

9

What are Ionic Bonds? (oppistley charged ions)

- The attraction between opsitley charged ions

10

Name the properties of an ion...

- High melting point
-Ions cannot conduct when solid- as they cant move
-Ions can conduct when theyre liquid

11

What happens when a group 1 metal reacts with a non metal? (charge)

- The ion formed has a positive charge as a negative electron has been discarded from the ion

12

What happens to a group 7 when they react with a metal?

-The ion formed has a negative charge as the hallogen gains a negative electron

13

What are ionic compounds when drawn?

-Giant lattices
