How does the moon's physical characteristics make it easier for scientists to study than the sun? Responses

A. The moon is closer to Earth so it is easier to see and visit.

B. The moon is solid so it is easier for astronauts to visit.

C. The moon is not as bright as the sun so it is easier to view through a telescope.

D. All of the other answer choices

2.Earth completes one rotation every 24 hours. The moon completes one rotation about every 28 days. How are the day/night cycles different on the moon and on Earth?
Responses

A. The moon's day/night cycle takes 28 days instead of 24 hours.

B. On the moon, it is always daytime.

C. On the moon, it is always nighttime.

D. The moon has a week/month cycle instead of a day/night cycle.

Scientists noticed that climate changes on Earth cycled through about every 11 years. The scientists realized the changes were affected by the sun. Which feature of the sun causes these Earth climate changes?
Responses

A. None of the other answer choices

B. Solar flares

C. The corona

D. Sunspots

1st question: The moon is closer to Earth so it is easier to see and visit.

2nd question: The moon has a week/month cycle instead of a day/night cycle.

3rd question: The corona

Explanation:

explanation:

metals have excess of electrons whereas non-metals have deficiency of electrons. thus, in order to gain stability metals easily donate their electrons to the non-metals.

for example, electronic configuration of sodium is and electronic configuration of phosphorous is .

when a phosphorous atom and sodium atom combine together then sodium will donate is extra one electron to the phosphorous atom. as a result there will be formation of ionic bond between sodium and phosphorous.

the reaction will be as follows.

there, are three sodium sodium atoms and each of them will donate its one extra electron to phosphorous atom. thus, the sub-shell of phosphorous gets completely filled.  

thus, we can conclude that electrons are transferred from atoms of sodium to atoms of phosphorous. this transfer makes the sodium atoms donate one electron and the phosphorous atoms to gain one electron. as a result, the sodium and phosphorus atoms strongly attract each other.

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.
