Which property would radon most likely have? A. It is stable. B. It is a solid. C. It is flammable. D. It is silver in color.

Answers

Answer 1

Answer: Answer: option A) it is stable.

Justification:

Radon (Rn) has atomic number 86. The electron distribution leads to the most stable configuration: the outermost shell (valence shell) is 6s² 6p⁶. That means that it has 8 valence electrons and, therefore, this shell is full. It will not accept more electrons ans will try to keep all of the ones it has.

This is the typical configuration of a noble gas. They are all in the group 18 of the periodic table (the last column). So, as the other noble gases, He, Ne, Ar, Kr, and Xe, Rn is very stable.

Answer 2

Answer: Answer: option A) it is stable.

Carbon -14 is an example of dating

Answers

Carbon-14 is a radioactive isotope of carbon and is used primarily in radiocarbon dating at archaeological sites since we know the half life for carbon-14 and the ratio of carbon-12 and carbon-14 a living thing probably had when it died and the difference in that ratio can tell us how old the object is.

The diagram shows a ball resting at the top of a hill. Which statement best describes the energy in this system

Answers

Answer:

Option A is correct.

A.The potential energy in the system is greatest at X.

Explanation:

A ball resting at the top of a hill will have greatest potential energy because when an object is at rest it tend to have greatest potential energy. When It moves from position X to Y the potential energy of the ball will decrease and its kinetic energy will increase.

Answer choices are listed below.

A.The potential energy in the system is greatest at X.

B.The kinetic energy in the system is greatest at X.
C.Total energy in the system decreases as the ball moves from X to Y.
D.Total energy in the system increases as the ball moves from X to Y.
