Over a period of 30 days a student studied the night sky and recorded his observations. One night he watched a shooting star str
eak across the sky. His curiosity led him to list all the possible things it could be, then after researching, analyzing and comparing each, he proposed that which of the following was the most logical identification of a "shooting star? Answer F asteroid G comet H meteor J moon
The most logical identification of a "shooting star" is a meteor. A meteor is basically any material from outerspace that falls to Earth. The main characteristic of a meteor is that from our point of view on the surface of the Earth it looks like a shooting star because we see a streak of light behind it. This light is simply dust and rock from the meteor burning up as it enters the Earth's atmosphere, leaving a "tail" of light behind it. Which to us looks like a shooting star.
The answer would be B, 7 valence electrons. <span>F is located
in the 1s-orbital and the second energy level, which in fluorine's case
is the outermost energy level, meaning it has <span>7 electrons</span></span>
