Certain "rules" of chemistry are used to simplify concepts when in fact sometimes these rules are often "broken." Place the proper word into each sentence illustrating some of these exceptions.

The question is incomplete but this is the complete question in picture format.

Explanation:

1. An ION is the violation of the rule that suggests that electron and proton will be equal in number for each atom.

2. An ISOTOPE violates the rule that number of neutrons always equals the number of protons.

3. The original term ELEMENT meant to be indivisible, a term that doesn't consider the modern understanding of atom splitting and radioactive decay.

4. Often depicted with a central nucleus with concentric rings housing electrons, the ORBITAL models incorrectly conveys the idea that electrons rotate around the nucleus in a predictable orderly fashion.

5. The large number of naturally existing isotopes violate the rule that adding the number of neutrons and protons will yield and accurate ATOMIC weight.

the answer is the first option

explanation:

just googled it m8. not that hard

lol

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.
