Chapter 2, Problem 1FIO
  1. A. The first shell corresponds to the first energy level, and it can hold up to 2 electrons. Hydrogen has one proton, so it has 1 electron and one vacancy. A helium atom has 2 protons, 2 electrons, and no vacancies.

Chapter 2, Problem 1FIO, A. The first shell corresponds to the first energy level, and it can hold up to 2 electrons. , example  1

  1. B. The second shell corresponds to the second energy level, and it can hold up to 8 electrons. Carbon has 6 electrons, so its first shell is full. Its second shell has 4 electrons and four vacancies. Oxygen has 8 electrons and two vacancies. Neon has 10 electrons and no vacancies.

Chapter 2, Problem 1FIO, A. The first shell corresponds to the first energy level, and it can hold up to 2 electrons. , example  2

  1. C. The third shell corresponds to the third energy level, and it can hold up to 8 electrons. A sodium atom has 11 electrons, so its first two shells are full; the third shell has one electron. Thus, sodium has seven vacancies. Chlorine has 17 electrons and one vacancy. Argon has 18 electrons and no vacancies.

Summary Introduction

The atoms are referred to as building blocks of all substances. In other words, it is the basic fundamental unit of the matter. In every atom, the uncharged neutron and positively charged protons are present in the nucleus whereas the negatively charged electron moves around the nucleus. Generally, the shell model system is used to study the valence status of an atom. The atomic number is the number of protons present in the atom which determines the type of the atom

Explanation of Solution

The given shell model consists of about eight atoms namely helium, neon, hydrogen, oxygen, carbon, sodium, chloride, and argon. Of this given atom in the model the hydrogen, carbon, oxygen, chlorine and sodium have unpaired electrons in the outer shell. These unpaired electrons are available to pair with other unpaired electrons in another atom. Thus these atoms combine to form molecules.

What are biofertilizers and mention the significance
PCBs and River Otters: Otters in Washington State’s Green-Duwamish River have high levels of polychlorinated biphenyls (PCBs) in their livers. PCBs can bind to the estrogen receptors in animals and disrupt the endocrine system of these otters. The PCBs seem to increase the estrogen to androgen ratio, skewing the ratio toward too much estrogen.     How would increased estrogen affect the river otter population? Based on your reading of the materials in this unit, what factors can affect fertility in humans?   Explain how each of the factors affecting human fertility that you described can disrupt the human endocrine system to affect reproduction.
Other than oil and alcohol, are there other liquids you could compare to water (that are liquid at room temperature)? How is water unique compared to these other liquids? What follow-up experiment would you like to do, and how would you relate it to your life?
