Chapter 8 Section 3: Activity Series of the Elements

Introduction

• In Chemistry, activity refers to an element's ability to react

• An Activity Series​ is a list of elements organized according to the ease with which the elements undergo certain chemical reactions

  • How likely is an element to take part in a reaction

    • Metals lose electrons at higher activity levels

    • non metals gain electrons

  • ​The order is determined by single replacement reactions

  • Elements can replace any element underneath them on the list, but not any element above them​

    • Halogens are special, they are in the exact order they are in on the Periodi​

Multiple Choice

Based on the activity series will the following reaction take place:

$$Zn_{\left(s\right)}+H_2O_{\left(l\right)}\ \frac{50\degree C}{\rightarrow}$$  

• Yes

• No

• Zinc only reacts with water when it is in Steam. Water boils at 100 Degrees Celsius, so this reaction will not take place

Multiple Choice

Based on the activity series will the following reaction take place:

$$Sn_{\left(s\right)}\ +O_{2\left(g\right)}\rightarrow$$  

• Yes

• No

Multiple Choice

Based on the activity series will the following reaction take place:

$$Cd_{\left(s\right)}+Pb\left(NO_3\right)_{2\left(aq\right)}\rightarrow$$  

• Yes

• No

Multiple Choice

Based on the activity series will the following reaction take place:

$$Cu_{\left(s\right)}+HCl_{\left(aq\right)}\rightarrow$$  

• Yes

• No

Multiple Choice

Based on the activity series will the following reaction take place:

$$MgCl_{2\left(aq\right)}+Zn_{\left(s\right)}\rightarrow$$  

• Yes

• No
