Explain the chemistry behind global warming in 3-5 sentences
Oliga [24]

Answer:

When factories mass produce something it produces smoke. That smoke can be harmful to something called the ozone layer. The ozone layer is part of earth's atmosphere that protects us from the suns burning heat. When that layer is damaged the sun's heat burns through heating up the world and melting ice causing the water levels to rise. All of this can make working conditions less safe, cause more flooding, and have the sun cause cancer.

Group 1 elements have an average electronegativity of 0.84 (not including hydrogen). Group 17 elements have an average electrone
aivan3 [116]

We have that the Electronegative difference of 2.15 basically makes ionic bonds

Ionic bonds is to be formed

<h3>Bonding</h3>

Generally, the common electronegativity of the team 1 <u>factors </u>are 0.84 and the common <em>electronegativity </em>of the team 17 factors are 2.99.

Group 17 factors are an awful lot greater electronegative than Group 1 elements.

Group 17 consists of F, Cl, Br and I,Group 1 factor that is Na loses 1 electron from its outermost orbit and varieties Na+ cation.

Group 17 Element that is Cl accepts 1 electron in its outermost orbit and Creates Cl- anion. Now, Na+ cation and Cl- anion combines collectively by using ionic bonds.

Hence, the electronegative difference

(2.99-0.84)=2.15

Electronegative difference of 2.15 basically makes ionic bonds
