(a)
Interpretation:
Number of protons, neutrons and electrons in fluorine - 23 should be written.
Concept introduction:
An atom consists of subatomic particles like protons, neutrons and electrons.
Answer to Problem 4E
Fluorine - 23 has 9 protons, 9 electrons and 14 neutrons.
Explanation of Solution
From the periodic table, one can see that atomic number of fluorine is 9
Number of protons = number of electrons = atomic number = 9
Fluorine -23 has mass number = 23
Mass number = number of protons + number of neutrons
Number of neutrons = mass number − number of protons
= 23 - 9
= 14
(b)
Interpretation:
Number of protons, neutrons and electrons in
Concept introduction:
An atom consists of subatomic particles like protons, neutrons and electrons. Atomic number denotes the number of protons or electrons in an atom. Mass number denotes the sum of number of protons and neutrons in an atom.
(b)
Answer to Problem 4E
Explanation of Solution
From the isotope symbol, one can see that atomic number of cobalt is 27
Number of protons = number of electrons = atomic number = 27
Mass number = number of protons + number of neutrons
Number of neutrons = mass number − number of protons
= 59 - 27
= 32
(c)
Interpretation:
Number of protons, neutrons and electrons in molybdenum - 96 should be written.
Concept introduction:
An atom consists of subatomic particles like protons, neutrons and electrons. Atomic number denotes the number of protons or electrons in an atom. Mass number denotes the sum of number of protons and neutrons in an atom.
(c)
Answer to Problem 4E
Molybdenum - 96 has 42 protons, 42electrons and 54 neutrons.
Explanation of Solution
From the periodic table, one can see that atomic number of molybdenum is 42
Number of protons = number of electrons = atomic number = 42
Molybdenum - 96 has mass number = 96
Mass number = number of protons + number of neutrons
Number of neutrons = mass number − number of protons
= 96 - 42
= 54
