-table sugar (C12H22O11)

Question 11

exist as molecules and
combination of two or more atoms

Answer 11

Compounds

Question 12

a molecule made from two atoms of the same type.

Answer 12

diatomic molecules

Question 13

chemical species with an overall electrical charge

Answer 13

Ion

Question 14

How are Ions formed?

Answer 14

when electrons move from one species to another and the overall number of protons and electrons changes

atoms gain or lose electrons
or a proton never comes out of an atom

Question 15

positively charged species
number of electrons < number of protons

Answer 15

Cation

Question 15

negatively charged species
number of electrons > number of protons

Answer 15

Anion

Question 16

typically lose electrons to form cations

Answer 16

Metals in Monoatomic ions

Question 17

Some metals can have more than one charge

Answer 17

multivalent ions

Question 18

typically gain electrons to form anions.

Answer 18

Nonmetals

Question 19

ions that contain more than one type of atom
atoms are held together by strong covalent bonds

Answer 19

Polyatomic Ions

Question 20

made from the combination of cations and anions

Answer 20

Ionic Compounds

Question 22

Ionic compounds are held together by strong —————- between oppositely charged ions

Answer 22

electrostatic forces

Question 23

True or false:

Ionic compounds are electrically positively charged

Answer 23

false

they are electrically neutral

Question 24

Trivia

Answer 24

Ionic compounds are solid at room temperature and requires high temperature to break the attraction of ions and melt the compound

Question 25

Answer 25

strong electrolytes

Question 26

species that do not conduct electricity

Answer 26

nonelectrolytes

Question 27

differentiate Atoms and Molecules

Answer 27

Atoms have one atom, molecules have more than one

Question 28

Differentiate Atoms and Ions

Answer 28

Atoms are electrically neutral, Ions have varied charges that can either be an Anion or a Cation
