Which statement explains why the noble gases are so unreactive? They have one valence electron. They have eight valence electron
SVETLANKA909090 [29]

Answer:

The answer to your question is: The second option.

Explanation:

Atoms are stable when they gain or lose electrons to have 8 electrons.

They have one valence electron.  Noble gases have 8 electrons, not one, If they would have 1 electron they would be extremely reactive.

They have eight valence electrons. This is the right answer, noble gases have 8 electrons that is why they are unreactive.

They have seven valence electrons.  If noble gases would have 7 electrons, they would be very reactive.

They have two valence electrons. This option is incorrect, elements that have 2 electrons are reactive like Calcium, Magnesium, etc.

Number 1 is incorrect, the genotypes are given to you. You need to use GG and gg. The outcome would be 100% Gg.

Number 2 is incorrect, the genotypes are given to you. You need to use Gg and Gg. The outcome would be 25% gg, 25% GG, and 50% Gg.

Number 3 is incorrect, the genotypes are given to you. You need to use TT and tt. The outcome would be 100% Tt.

Number 4 is incorrect, the genotypes are given to you. You need to use RR and rr. The outcome would be 100% Rr.

Please read the directions and use the genotypes they give you! The information is all there for you, you just need to put it in correctly. If you're still having trouble understanding how to do this, feel free to message me and I'd be happy to help you.
