This Exam contains:
-Guarantee passing score -15 Questions and Answers -format set of multiple-choice -Expert- Explanation Question 1: The top row of the inner transition metals is the [...] (it starts with lanthanum (La))
Answer:
The top row of the inner transition metals is the Lanthanides (it starts with lanthanum (La)) Question 2: Uranium has an atomic number of 92, so any element with an atomic number greater than 92 is a [...] element.
Answer:
Uranium has an atomic number of 92, so any element with an atomic number greater than 92 is a transuranium element.Question 3: The bottom row of the inner transition metals is the [...] (it starts with actinide (Ac))
Answer:
The bottom row of the inner transition metals is the actinides (it starts with actinide (Ac)) Question 4: One of the interesting things about the inner transition metals is that these elements are so [...] in properties that they are often hard to [...].
Answer:
One of the interesting things about the inner transition metals is that these elements are so similar in properties that they are often hard to tell apart.
Question 5: The two rows of elements at the very bottom of the periodic table are the [...]
Answer:
The two rows of elements at the very bottom of the periodic table are the inner transition metals Question 6: As the actinide-series element nuclei decay, they emit [...]. This is called [...]active decay.
Answer:
As the actinide-series element nuclei decay, they emit radiation. This is called radioactive decay.Question 7: Most of the elements in the actinide series are [...] elements, which are not found on Earth unless produced in a laboratory.
Answer:
Most of the elements in the actinide series are transuranium elements, which are not found on Earth unless produced in a laboratory.Question 8: If you want to find an element that's only made in a laboratory, just look past [...].
Answer:
If you want to find an element that's only made in a laboratory, just look past uranium.Question 9: Actinide-series elements have nuclei that are so large that they tend to [...] (usually into a smaller nucleus).
Answer:
Actinide-series elements have nuclei that are so large that they tend to break down or decay (usually into a smaller nucleus).
Question 10: All elements of the [...] series are radioactive.
Answer:
All elements of the actinide series are radioactive.Question 11: The inner transition metals are sometimes referred to as the [...] metals.
Answer:
The inner transition metals are sometimes referred to as the rare earth metals.
Question 12: [...]-uranium just means 'beyond uranium'.
Answer:
Trans-uranium just means 'beyond uranium'.Question 13: Interesting Factoid: Uranium has been used for nearly [...] years as an additive to ceramics.
Answer:
Interesting Factoid: Uranium has been used for nearly 2,000 years as an additive to ceramics.Question 14: Out of the 14 elements in the actinide series, only thorium and [...] occur in nature in any significant quantity.
Answer:
Out of the 14 elements in the actinide series, only thorium and uranium occur in nature in any significant quantity.Question 15: The heaviest naturally occurring element on Earth is [...]. (probably... there may be a few traces of larger elements out there).
Answer:
The heaviest naturally occurring element on Earth is Uranium. (probably... there may be a few traces of larger elements out there).
