Question 1

What are isotopes?

Answer 1

Same element with a different number of neutrons in their nucleus which results in a changed mass number

Question 2

Name some examples of polyatomic ions

Answer 2

Sulfate and hydroxide

Question 3

What are the 4 specific covalent molecular substances that we have to know?

Answer 3

IDK

Question 4

Name a metal which is an exception to the high melting point physical property (douevenenglishbrah)

Answer 4

Mercury

Question 5

In order for something to conduct electricity what does it need to have?

Answer 5

Mobile charged particles

Question 6

What does a very high melting/boiling point mean?

Answer 6

Strong covalent bonding extending throughout the lattice

Question 7

For a covalent bond what does non-conductivity of electricity in a solid/liquid form mean?

Answer 7

Electrons are fixed

Question 8

What is the one exception

Answer 8

Graphite don’t ask me why

Question 9

For a covalent bond what does hard and brittle mean?

Answer 9

Atoms strongly bound, distortion breaks

Question 10

For a covalent bond what does insolubility in water and most other solvents mean?

Answer 10

Strongly bonded throughout the lattice

Question 11

For a metallic bond what does a high melting/boiling point mean?

Answer 11

strong metallic bonds exist throughout the lattice

Question 12

In a metallic bond what does a relatively high density suggest

Answer 12

ions are tightly packed in the lattice

Question 13

For an ionic bond what does hard and brittle mean?

Answer 13

Ions are tightly bound by electrostatic forces in the lattice

Question 14

In an ionic bond why is electrical conductivity when in solid form not a thing?

Answer 14

Electrons are fixed
