module 2 section 1 defenitions

Question 1

Define ionic bonding (2)

Answer 1

• Electrostatic attraction
• between + and - ions

Question 2

Define electrostatic attraction (3)

Answer 2

• 2 particles
• with opposite charge
• that attract

Question 3

What is meant by a bond? ()

Answer 3

• a region of electron density

Question 4

define covalent bonding (3)

Answer 4

• strong electrostatic attraction
• between a shared pair of electrons
• and nuclei if bonded atoms

Question 5

Define electronegativity (2)

Answer 5

• Ability of an electron to attract a pair of electrons towards itself
- in a covalent bond

Question 6

Define polar molecule (3)

Answer 6

• A molecule that contains - polar bonds
• with dipoles
• that don’t cancel outdie to their direction

Question 7

define induced dipole dipole interactions (4)

Answer 7

• intermolecular forces
• caused by random movement of electrons
• creating a temporary dipole
• that induces a dipole in neighbouring molecule

Question 8

define permanent dipole dipole interactions (2)

Answer 8

• weak intermolecular forces of attraction
• between polar molecules

Question 9

define hydrogen bonding (3)

Answer 9

• intermolecular bonding
• between molecules containing N,O or F
• and the H atom of NH, OH or HFB
