What is the nature of new elements added to the periodic table in the last hundred years? A. All were discovered naturally. B. All were synthesized artificially. C. Some were discovered and some were synthesized. D. No new elements have been added to the periodic table in that time.

Answers

Answer 1

Answer: C

Explanation: I just got it right on ck12

Answer 2

The periodic table is an arrangement of elements in rows and periods. The correct answer is option C. Some were discovered and some were synthesized.

In the modern periodic table, elements are arranged in order of increasing atomic numbers.

Most of the elements that were discovered before the 1900s were discovered naturally. After 1900, a few elements that occur naturally but are high radioactive with extremely short half lives have been discovered such as Technetium.

However, in the past 100 years, many elements have been synthesized  and added to the periodic table. To synthesize an element means to produce the element in a laboratory by bombarding an existing element with particles such as protons and neutrons.

Which sentence best shows the resolution of the passage? Jessica was in class, but she was bored and sleepy. Suddenly, she heard a noise outside the classroom door. She heard it again and realized that she was the only one who could hear it. As she walked to the door, she realized something even more astonishing. No one in the classroom could see her. She had become invisible! Jessica nervously opened the door and stepped outside. To her horror, she found herself on a battlefield with thousands of men in red and blue coats fighting one another. Terrified, she turned back to the classroom door but couldn’t find it. Knowing that she was trapped in this strange war made her hands and feet go cold and her heart begin to pound. Out of nowhere, an unmanned horse began running toward her. Jessica tried to flee, but the horse was fast and caught up to her. She screamed as the horse’s hooves descended upon her. Then everything went dark. Jessica woke up to realize that she was still in her classroom and that she’d been dreaming all along. The dream had been about the American Civil War, which her teacher had been discussing in class. Jessica was extremely relieved to be safe in class. She would much rather learn about a war than be a part of one.

C. Hancock wishes she had a goose to roast for the infirm.
D. Hancock admires the men who pray for food, rather than curse for it.

Answers

Answer: B. The wounded men are suffering further because of a lack of food.

Explanation:

Hancock, who is the speaker in this passage, notes that some days they will have nothing to cook with such that they have to feed their men with dry bread and poor coffee instead of proper food.

These men were already wounded and so were already suffering. A lack of food will make them suffer even more. This is why Hancock notes that some will curse and some will pray because that is how they will react to the further suffering.

Read the passage from chapter 17 of The Prince.

Cesare Borgia was considered cruel; notwithstanding, his cruelty reconciled the Romagna, unified it, and restored it to peace and loyalty. And if this be rightly considered, he will be seen to have been much more merciful than the Florentine people, who, to avoid a reputation for cruelty, permitted Pistoia to be destroyed.
