Concept explainers
Interpretation: The name of element that includes the first letter of its name as the first of
Concept Introduction: Every matter is made of chemicals; the importance of chemistry is that it's the study of everything. Chemistry is all about how something interacts to affect the structure, composition, as well as knowing properties of substances.
Answer to Problem 1STP
Correct answer: The correct option is C.
Explanation of Solution
Reason for correct option: Symbol of any chemical is a short hand way to represent any element. It tells us what atom it is. First letter code for a chemical element is always capital. The periodic table is a very useful way to arrange elements.
Copper is the only one in the list that has the first letter of its name as the first letter of its symbol. Symbol of Copper is Cu.
Reasons for incorrect options:
Option A: Symbolic representation of Potassium is K. So, this is an incorrect option.
Option B: Symbolic representation of Lead is Pb. So, this is an incorrect option.
Option D: Symbolic representation of Sodium is Na. So, this is an incorrect option.

If substitution would not occur at a significant rate under these conditions, check the box underneath the drawing area instead. Be sure you use wedge and dash bonds where necessary, for example to distinguish between major products. Note for advanced students: you can assume that the reaction mixture is heated mildly, somewhat above room temperature, but strong heat or reflux is not used.
