Flashcards in Ionic, covalent and metallic bonding Deck (20):
1

Which bonding is with two metals ?

Metalic

2

Which bonding is with two non-metals ?

Covalent

3

Which bonding is with a metal and a non-metal ?

Ionic

4

How does ionic bonding occur ?

When the metals want to lose electrons and the non-metals want to gain electrons. They do this so they both have a full outer shell.

5

What is it called when an ion gets a full outer shell if it is not a Nobel gas ?

stable

6

What is it called when a Nobel gas has a full outer shell as they always do ?

inert

7

what charge does the metal have when it looses an electron ?

positive

8

what charge does the metal have when it gains an electron ?

negative

9

what are the 7 steps to drawing an ion ?

1. draw a nucleus
2. add the protons and neutrons inside the nucleus
3. draw shells
4. add electrons (not any that have been lost)
5. add square bracket
6. add charge
7. put electronic configuration underneath ion with square bracket and charge on it

10

What must you draw before drawing the ion ?

the atom at the beginning

11

when drawing an ion that has gained electrons how must you draw them on the ions shells ?

in a different shape (if the electrons on the atom are crosses put them on as circles)

12

if the metal lithium gives an electron to the non-metal fluorine what name does it now have ?

lithium fluoride

13

what is the attraction between the ions called ?

electrostatic attraction

14

what are the steps to drawing an ion when there is more than one atom involved ?

draw it the same as before but put a times sign and then the number of atoms included (if you were using 3 fluroines put a X3 outside the bracket at the bottom corner)

15

what are the 6 steps to knowing which ion has a higher melting and boiling point ?

1. draw both ions
2. (ion name) has charges of ......+ and ........-
3. ion name) has charges of ......+ and ........-
4. (ion name with more + charge) has a stronger electrostatic attraction
5. this means more energy is needed to break the (ion name) bonds
6. so it has a higher melting and boiling point

16

what is the name of the form of a group of oppositely charged ions ?

a giant ionic lattice

17

what happens when a substance is brittle ?

it breaks because the pressure has moved the oppositely charged ions so they repel because they are aligned with ions of the same charge

18

why can't ionic substances conduct electricity ?

electricity is the movement of charged particles, but ionic substances don't have any electrons that can move, even though they have ions but they are in a lattice so they can't move either

19

what does aqueous mean ?

dissolved in water

20

what does molten mean ?

this allows the ions to move
