Metallic And Ionic Bonding

Question 1

Define ionic bonding

Answer 1

The strong electrostatic attraction between oppositely charged ions

Question 2

How do you increase the strength of an ionic bond

Answer 2

Increasing the ionic charge
Decreasing the ionic radii

Question 3

How do ions form

Answer 3

Cations is the loss of electrons
Anions is the gain of electrons

Question 4

What are isoelectric ions

Answer 4

Ions that have the same number of electrons and electronic structure

Question 5

What is the trend in ionic radii across a period of isoelectric ions

Answer 5

As the number of protons increases, the ionic radius decreases because as the positive charge of the nucleus increases, the electrons are attracted more strongly and are therefore pulled closer to the nucleus

Question 6

What are the physical properties of ionic compounds

Answer 6

High melting points
Brittleness
Poor electrical conductivity when solid but good when molten
Often soluble in water
