Flashcards in Ch 8 Section 3 Deck (20):
1

ability of an element to react is referred to as the element's

activity

2

the more readily an element reacts with other substances, the

greater the activity is

3

an activity series is a list of elements organized according to the

ease with which the elements undergo certain chemical reactions

4

for metals, greater activity means a greater ease of

loss of electrons, to form positive ions

5

for nonmetals, greater activity means a greater ease of

gain of electrons, to form negative ions

6

the order in which the elements are listed is usually determined by

single-displacement reactions

7

the most-active element, placed at the top in the series, can replace each of the

elements below it from a compound in a single-displacement reaction

8

an element farther down can replace any element

below it but not any above it

9

each halogen will react to replace any halogen listed

below it in the periodic table

10

activity series are used to help predict whether

certain chemical reactions will occur

11

activity series are based on

experiment

12

the information that activity series contain is used as a general

guide for predicting reaction outcomes

13

activity series reflects the fact that some metals react

vigorously with water and acids, replacing hydrogen to from new compounds

14

other metals replace hydrogen in acids but react with water only when

the water is hot enough to become steam

15

Li, Rb, K, Ba, Sr, Ca, Na
React with cold H2O and

acids, replacing hydrogen. React with oxygen, forming oxides

16

Li, Rb, K, Ba, Sr, Ca, Na;
activity of halogen nonmetals

F2, Cl2, Br2, I2

17

Mg, Al, Mn, Zn, Cr, Fe, Cd
react with steam (but not cold water) and

acids, replacing hydrogen. react with oxygen, forming oxides

18

Co, Ni, Sn, Pb,
Do not react with

water. react with acids, replacing hydrogen. react with oxygen, forming oxides

19

H2, Sb, Bi, Cu, Hg
react with

oxygen, forming oxides

20

Ag, Pt, Au
fairly unreactive, forming

oxides only indirectly
