Ionic Bonding

Question 1

Ionic bonding?

Answer 1

When a metal and a non-metal react together

Question 2

Transfer of electrons

Answer 2

The metal atom loses electrons and the non-metal gains those electrons

Question 3

Positive ion

Answer 3

Cation (metal)

Question 4

Negative ion

Answer 4

Anion (non-metal)

Question 5

When oppositely charged ions are strongly attracted (electrostatic attraction)

Answer 5

Ionic bond

Question 6

Dot and cross diagram

Answer 6

Show the arrangement of electrons in an atom or ion. Shows where the dot or cross originally came from.

Question 7

Sodium Chloride (NaCI)

Answer 7

The sodium atom gives up its outer electron, becoming an Na (+) ion. The Chlorine atom picks up the electron, becoming a CI(-) ion.

Question 8

Ionic compounds have a…..

Answer 8

…..regular lattice structure

Question 9

Regular Lattice Structure

Answer 9

Ions form a closely packed regular lattice. There are very strong electrostatic forces of attrition between oppositely charged ions, in all directions.

Question 10

Properties

Answer 10

High melting/boiling points-strong attraction between ions
Don’t conduct electricity in solid state-fixed in place
Conducts electricity when melted-electrons are free to move
Dissolves easily- can carry an electrical charge- ions separate and free to move
