Transcript text: Question 1
The term "heavy metals:"
Is related to the chemical composition of all toxic metals
Accurately describes the high density of all toxic metals
All of these are true
Originated from the discovery of the toxicity of relatively dense mercury and lead
Solution
Solution Steps
Step 1: Analyze the given options
We need to determine which statement accurately describes the term "heavy metals."
Step 2: Evaluate each option
"Is related to the chemical composition of all toxic metals" - This is not entirely accurate as "heavy metals" is more commonly associated with density rather than chemical composition.
"Accurately describes the high density of all toxic metals" - This is partially true, but not all toxic metals are necessarily heavy.
"All of these are true" - This would only be correct if all individual statements were true, which they are not.
"Originated from the discovery of the toxicity of relatively dense mercury and lead" - This is historically accurate as the term "heavy metals" was indeed influenced by the toxicity of dense metals like mercury and lead.
Final Answer
\(\boxed{\text{Originated from the discovery of the toxicity of relatively dense mercury and lead}}\)
