Verified step by step guidance1
Understand the meaning of the term 'trace' in a chemical context. 'Trace' generally refers to something present in very small quantities.
Consider the options given: whether the element is present in very small amounts, essential for all chemical reactions, found only in labs, or radioactive.
Recall that a 'trace element' in chemistry and biology is an element required by organisms in minute amounts, or simply present in very small quantities in a sample or environment.
Eliminate options that do not fit the common usage of 'trace' in chemistry, such as being radioactive or only found in labs, since these are unrelated to the quantity implied by 'trace.'
Conclude that the adjective 'trace' means the element is present in very small amounts.
