The outer shell of this element was determined as illustrated here. It must be a _____.

: light metal
: heavy metal
: non metal
: noble gas

The outer shell of the given element was determined as illustrated must be a noble gas. Therefore, option D is correct.

Noble gases can be described as the 6 elements that are organized in group 18 of the modern periodic table. The noble gases are Helium, Neon, Argon, Krypton, Xenon, and Radon.

Under standard temperature and pressure, noble gases exist in the gaseous form and possess low reactivity. Therefore, noble gases are also referred to as inert gas.  All the noble gases exhibit stable electronic configurations in their valence shell that are completely filled. Noble gases generally exist as monoatomic.

The general outer configuration of the noble gases can be written as ns²np⁶,  n is the principal quantum number. Therefore, the given electron dot diagram has eight electrons in its valence shell so it is representing a noble gas.

Which paragraph from the article explains why the ultracool dwarf star discovery is so
significant to the search for other signs of life?
The system's host star, called TRAPPIST-1, is what is known as an ultracool dwarf. It is about
one-tenth the size of our sun and just a bit bigger than Jupiter.
Going forward, the authors plan to use even more powerful telescopes to analyze the
TRAPPIST-1 system. The Hubble Space Telescope will point its powerful lens toward the
ultracool dwarf star.
O "Systems around these tiny stars are the only places where we can detect life on an Earth-
sized exoplanet with our current technology," Gillon said in a statement. "If we want to find
life elsewhere in the Universe, this is where we should look."
O Ultracool dwarfs make up about 15 percent of the astronomical objects in our immediate
neighborhood, but until now, no one had ever discovered a planet orbiting one.
