Question
Chapter 21, Problem 21.6QP
Interpretation Introduction
Interpretation:
The three different methods for refining a metal have to be briefly described.
Concept introduction:
Metals:
- Metal is material which can be an element, compound, or alloy and is hard.
- Metals prepared by reduction usually need further treatments to remove impurities.
- The purification depends on how the metal will be used and there are three common purification methods.

No, it has the wrong number of valence electrons.
The correct number is: ☐
No, it has the right number of valence electrons but doesn't satisfy the
octet rule.
The symbols of the problem atoms are:* ☐
Yes.
No, it has the wrong number of valence electrons.
The correct number is: ☐
No, it has the right number of valence electrons but doesn't satisfy the
octet rule.
The symbols of the problem atoms are:* |
Yes.
No, it has the wrong number of valence electrons.
The correct number is:
No, it has the right number of valence electrons but doesn't satisfy the
octet rule.
The symbols of the problem atoms are:* |
If two or more atoms of the same element don't satisfy the octet rule, just enter the chemical symbol as many
times as necessary. For example, if two oxygen atoms don't satisfy the octet rule, enter "0,0".
