Flashcards in Compounds & Mixtures - Cornell Notes Deck (15):
1

True or False?

Compounds have similar physical and chemical properties to their individual elements.

False

2

Electrons ready to bond are called

Valence electrons

3

Formed when one or more electrons are transferred from one atom to another

Ionic bond

4

When an element loses an electron, it becomes

Positively charged

5

When an element gains an electron, it becomes

Negatively charged

6

The attraction between two oppositely charged ions

Ionic bond

7

Positively and negatively charged atoms

Ions

8

Occur when electrons are shared by atoms

Covalent bond

9

Nonmetal + Nonmetal =

Covalent bond

10

Metal + Nonmetal =

Ionic bond

11

In a Louis Dot Diagram, shared electrons are represented by a(n)

Dash

12

The structure that forms when atoms are joined by covalent bonds

Molecule

13

Intermolecular forces of attraction that occur between oppositely charged regions of nearby molecules

Van der Waals forces

14

The universal solvent

Water

15

Why is water the universal solvent?

Its polarity gives it the ability to dissolve both ionic and other polar molecules (due to like charges)
