(a)
Interpretation: The number of protons and electrons in Cs element needs to be determined.
Concept Introduction: An atom is composed of protons, neutrons, and electrons. Here, protons and neutrons are present in the nucleus of an atom and electrons are present in atomic orbitals around the nucleus. The
(a)
Answer to Problem 103A
55
Explanation of Solution
The given element is caesium (Cs). The atomic number and mass number of Cs are 55 and 133 respectively. Since the atomic number is equal to the number of protons and electrons in an atom, the number of protons and electrons in Cs atom is 55.
(b)
Interpretation: The number of protons and electrons in Ag element needs to be determined.
Concept Introduction: An atom is composed of protons, neutrons, and electrons. Here, protons and neutrons are present in the nucleus of an atom and electrons are present in atomic orbitals around the nucleus. The atomic number of an atom is equal to the number of protons and electrons in it. Atomic mass is the sum of the number of protons and neutrons.
(b)
Answer to Problem 103A
47
Explanation of Solution
The given element is silver (Ag). The atomic number and mass number of Ag are 47 and 108 respectively. Since the atomic number is equal to the number of protons and electrons in an atom, the number of protons and electrons in Ag atom is 47.
(c)
Interpretation: The number of protons and electrons in Cd element needs to be determined.
Concept Introduction: An atom is composed of protons, neutrons, and electrons. Here, protons and neutrons are present in the nucleus of an atom and electrons are present in atomic orbitals around the nucleus. The atomic number of an atom is equal to the number of protons and electrons in it. Atomic mass is the sum of the number of protons and neutrons.
(c)
Answer to Problem 103A
48
Explanation of Solution
The given element is cadmium (Cd). The atomic number and mass number of Cd are 48 and 112 respectively. Since the atomic number is equal to the number of protons and electrons in an atom, the number of protons and electrons in the Cd atom is 48.
(d)
Interpretation: The number of protons and electrons in Se element needs to be determined.
Concept Introduction: An atom is composed of protons, neutrons, and electrons. Here, protons and neutrons are present in the nucleus of an atom and electrons are present in atomic orbitals around the nucleus. The atomic number of an atom is equal to the number of protons and electrons in it. Atomic mass is the sum of the number of protons and neutrons.
(d)
Answer to Problem 103A
34
Explanation of Solution
The given element is selenium (Se). The atomic number and mass number of Se are 34 and 79 respectively. Since the atomic number is equal to the number of protons and electrons in an atom, the number of protons and electrons in the Se atom is 34.
