Flashcards in Bonding Deck (12):
1

Ionic - what is the attraction called?

Electrostatic attraction

2

Ionic- the higher the charge.....

The higher the melting point

3

Ionic - lose electrons

Oxidation

4

Ionic - gain electrons

Reduction

5

What is ionic bonding between?

Metals and non metals, create compounds

6

What is covalent bonding between?

Non metals, nucleus and electrons, creates elements/compounds

7

What is metallic bonding between?

Metals, positive metal ions and delocalised electrons, elements

8

What are the properties of metallic elements?

Magnetic, conductors, malleable and ductile because whenever the cation gets hit, the electron flows with it making it hard to break (doesn't have rigid bonds) , are giant structures of positive ions surrounded by a sea of delocalised electrons.

9

About diamonds

- 4 covalent bonds
- insulator ( no free electrons )
- strong: millions of strong covalent bonds
- used in cutting because they are so strong

10

About graphite

- 3 covalent bonds
- conductor ( 1 free electron )
- soft: lots of strong covalent bonds but have weak intermolecular forces
- used as a lubricant because the covalent bonds slide over each other

11

What have simple structures

Usually gases/liquids
- have low melting point
- weak intermolecular forces

12

Giant covalent structures

High melting points, strong intermolecular forces
