Question

certain
ules\ 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. 1. a(n) (click to select) is a violation of the
ule\ that suggests that electrons and protons will be equal in number for each atom. 2. a(n) violates the
ule\ that the number of neutrons always equals the number of protons. 3. the split meant \to be indivisible,\ a term that does not consider the modern understanding of atom - ive decay. 4. often the model incorrectly conveys a central nucleus with concentric rings housing electrons, the (click to select) model incorrectly conveys electrons rotate around the nucleus in a predictable, orderly fashion. 5. the naturally existing isotopes violates the
ule\ that adding the number of neutrons and protons will yield an a weight.

Explanation:

1. An ion has a different number of electrons and protons.
2. Isotopes have varying numbers of neutrons relative to protons.
3. The term "atom" originally meant indivisible, but modern - understanding includes nuclear decay.
4. The planetary model inaccurately represents electron motion.
5. Some isotopes have a mass number different from the sum of neutrons and protons due to binding energy effects.

Answer:

1. ion
2. isotope
3. atom
4. planetary
5. atomic
