Chemistry Quiz

Question 1

Element

Answer 1

A substance that can’t be broken down any further + made of one kind of atom (negative)

Question 2

Valence Electrons

Answer 2

Electrons in the outermost shell

Question 3

Difference between ionic and covalent bonding?

Answer 3

ionic bond - one atom transfers electron to another atom (creates a positive and negative ion)

covalent bond - atoms share electrons

Question 4

Ionic bonds form between what?

Answer 4

metals and nonmetals

Question 5

Covalent bonds form between what?

Answer 5

nonmetals

Question 6

What are diatomic molecules made of?

Answer 6

2 atoms of the same element combined together

Question 7

Electronegnativity

Answer 7

the tendency of an atom to attract an electron.

Question 8

What is the relationship between electronegnativity and valence electrons?

Answer 8

As the number of valence electrons increases, electronegativity increases

Question 9

What kind of atom has the highest electronegativity?

Answer 9

Atoms with a small atomic radius and many electrons

Question 10

What is a hydrogen bond?

Answer 10

A weak attraction between a partially positive hydrogen and partially negative atom

Question 11

What is hydrogen bonding responsible for?

Answer 11

• Water’s high boiling point
• Water’s special properties
  (cohesion, adhesion, and
  surface tension)

Question 12

What is a chemical reaction?

Answer 12

The process that leads to the change of one set of chemical substances into another (a chemical change)

Question 13

What type of reaction do bubbles indicate?

Answer 13
