Bonding

Question 1

definition of Ionic bonding

Answer 1

the electrostatic attraction between oppositely charged ions which occurs between metals and non-metals

Question 2

what does an compound/ion have to have to be able to conduct electricity

Answer 2

• distance between particles
• ion/electrons have to move freely and pass the electrical current

Question 3

what does the strength of the ionic bonds between atoms depend on

Answer 3

charge of the ions. atoms with higher charge has stronger electrostatic forces

Question 4

features of giant ionic lattice structures

Answer 4

• held together by strong electrostatic forces of attraction
• the electrostatic forces acts in all directions
• formed between oppositely charged ions

Question 5

why ionic compounds are solid at room temperature

Answer 5

• strong electrostatic forces between atoms
• needs a lot of energy to break the forces

Question 6

electrical conductivity of ionic compounds

Answer 6

conduct electricity in liquid form
- solid: ions and electrons are locked into position, current can’t flow
- ions and electrons free to move, carry electric current

Question 7

definition of covalent bonding

Answer 7

the electrostatic attraction between a shared pair of electrons to the nuclei of an atom. it is a bond between a non-metal and non-metal

Question 8

what is the structure made of separate molecules (covalent bonding)

Answer 8

simple molecular

Question 9

features of simple molecular substances

Answer 9

• strong covalent bond within each molecules
• weak intermolecular forces between molecules
• low melting and boiling points
• don’t conduct electricity

Question 10

what is the structure of giant covalent structures

Answer 10

one huge molecule/structure

Question 11

features of the giant covalent structure

Answer 11

• no charged ions
• strong covalent bonds through out the entire structure
• high melting and boiling point
• don’t conduct electricity
