Answer:
When observing how thallium reacts with the air of the earth's atmosphere, its hardness or resistance resembled sodium, it was not investigated further to classify it correctly
Explanation:
Now it is known that they contain different numbers of valence electrons and that thallium is a heavy metal like lead and that they have similar characteristics except for their melting point where thallium is higher.

<h3>
Answer:</h3>
Higher or lower pH affect the structure of the enzyme and reduces the enzyme activity.
<h3>
Explanation:</h3>
- Enzymes are biological molecules that speed up the rate of chemical reactions.
- Enzyme activity is affected by several factors which include temperature, pH, and enzyme inhibitors.
- Enzymes work on specific molecules known as substrates. They are substrate-specific.
- Enzymes work best at optimum pH and temperature.
- Higher or lower pH affects the structure and charges of an enzyme thus affecting enzyme activity.
- Lower temperature deactivates the enzymes while higher temperatures denature the enzymes.
