Chapter 2

Question 1

What is always the charge of Zn?

Answer 1

+2

Question 2

what is always the charge of Ag?

Answer 2

+1

Question 3

When do you need a roman numeral?

Answer 3

when naming metals that can form more than one kind of cation

ex: Iron (Fe) can have a charge of 2+ or 3+ so you need to specify which [Fe (II) or Fe (III)]

Question 4

Difference between -ous and -ic?

Answer 4

“ous”–“ite”
“ic”–“ate”
“ous” is used on the oxoacid with the fewer amount of Oxygen atoms
“ic” is used on the oxoacid with the greater amount of oxygen atoms

Question 5

J.J Thomson

Answer 5

discovery of the electron

Question 6

Aristotle

Answer 6

no smallest “piece” of matter- continuous

Question 11

Isotopes

Answer 11

atoms with identical atomic numbers but different mass numbers

Question 12

Atomic mass

Answer 12

the weighted average of the isotopes masses of the elements naturally occurring isotopes

Question 13

nucleons

Answer 13

neutrons + protons

Question 14

nuclear chemistry

Answer 14

study of propertied and reactions of atomic nuclei

Question 15

Answer 17

have a charge of +2 and mass of 4 amu (He)

Question 18

beta rays (β)

Answer 18

have a charge of -1 and no mass (-1e on product side of equation)

Question 19

gamma rays (𝛾)

Answer 19

form of light energy (not particle like beta or alpha)

Question 20

ionizing ability

Answer 20

gamma

Question 21

penetrating ability

Answer 21

alpha

Question 22

positron emission

Answer 22

similar to beta, but instead of -1e on product side, it is +1e

Question 23

electron capture

Answer 23

similar to beta, but instead of -1e on product side, it is on the reactant side
