Answer 10

False

Question 11

Turue or false: Metals become cations

Answer 11

True

Question 12

True or false: Non Metals become anions

Answer 12

True

Question 13

True or false: Non Metals become cations

Answer 13

false

Question 14

How do we name cations?

Answer 14

name of elements + ion

Question 15

How do we name anions?

Answer 15

Drop the end replace with ide

Question 16

What is meant by atoms losing or gaining electrons to become like the nearest noble gas?

Answer 16

They gain or lose electrons to become like the nearest noble gas in terms of atomic number.

Question 17

What does the highlighted section show?

Answer 17

Metals

Question 18

Answer 18

Non-metals

Question 19

When 2 oppositely charged ions become attracted to eachother and become held together, what do we call this?

Answer 19

Ionic bond

Question 20

How are crystal lattices made up of a perfect pattern?

Answer 20

They form when oppositely charged ions are held together by strong electrostatic forces. The anion repels the anion of other ionic compounds, and attracts the cations, and vice versa. This causes a pattern as ions become attracted to the opposite ion, and repels ions of the same charge simultaneously.

Question 21

What are ionic bonds made out of?

Answer 21

Metal (cation) + non-metal (anion)

Question 22

How do we name ionic compounds?

Answer 22

name of cation + name of anion (anion must have the end replaced with ide)

Question 23

Complete the following

Answer 23

Question 24

Complete the folllowing

Answer 24

Question 25

What is a bronsted-lowry acid?

Answer 25

Any substance that donate a proton (H+, hydrogen ion specifically) during a reaction.

Question 26

What do you call a bronsted-lowry acid that loses one proton when it reacts?

Answer 26

monoprotic acids

Question 27

What do you call a bronsted-lowry acid that loses two proton when it reacts?

Answer 27

Diprotic acids

Question 28

What do you call a bronsted-lowry acid that loses three proton when it reacts?

Answer 28

Triprotic acids

Question 29

What do you call diprotic and triprotic acids?

Answer 29

Polyprotic acids

Question 30

Complete the following

Answer 30

Question 31

whats the term used to refer to how basic a substance is?

Answer 31

alkalinity

Question 32

Atomic mass vs mass number

Answer 32

Mass Number (A) → The total number of protons and neutrons in an atom’s nucleus. It’s always a whole number (e.g., Carbon-12 has a mass number of 12). Atomic Mass → The average mass of an element’s atoms, considering the relative abundance of its isotopes. It’s typically a decimal value (e.g., Carbon’s atomic mass is 12.011 u, due to isotopes like Carbon-13).
