(a)
Interpretation: The number of protons in nitrogen-
Concept introduction: Isotopes of a particular element have different number of neutrons. The mass number of an atom is the total number of protons and neutrons in the nucleus. In a neutral atom, number of protons in a nucleus is equal to the number of electrons.
Answer to Problem 1.1P
The number of protons in nitrogen-
Explanation of Solution
Atomic number of nitrogen is
The number of protons in nitrogen-
(b)
Interpretation: The number of protons in nitrogen-
Concept introduction: Isotopes of a particular element have different number of neutrons. The mass number of an atom is the total number of protons and neutrons in the nucleus. In a neutral atom, number of protons in a nucleus is equal to the number of electrons.
Answer to Problem 1.1P
The number of neutrons in nitrogen-
Explanation of Solution
Number of neutrons is calculated by the formula,
The number of protons in nitrogen-
Substitute the value of number of protons in nitrogen-
Hence, the number of neutrons is nitrogen-
The number of protons in nitrogen-
Substitute the value of number of protons and mass number in the above formula.
Hence, the number of neutrons is nitrogen-14 is
The number of neutrons in nitrogen-
(c)
Interpretation: The number of electrons in the neutral atom is to be predicted.
Concept introduction: Isotopes of a particular element have different number of neutrons. The mass number of an atom is the total number of protons and neutrons in the nucleus. In a neutral atom, number of protons in a nucleus is equal to the number of electrons.
Answer to Problem 1.1P
The number of electrons in the neutral atom is 7.
Explanation of Solution
Atomic number of nitrogen is
The number of electrons in neutral atom is 7.

The creditor realizes that this litigation could result in partnership liquidation and does not wish to force such an extreme action unless Zed is reasonably sure of obtaining at least $4,000 from the liquidation. Determine the amount for which the partnership must sell the other assets to ensure that Zed receives $4,000 from the liquidation. Liquidation expenses are expected to be $20,000.
