How many protons and neutrons are contained in the nucleus of each of the following atoms? Assuming each atom is uncharged, how many electrons are present?
a.
b.
(a)
Interpretation:
Determine the number of protons, neutron and electron in the given atom.
Concept Introduction:
The atomic symbol notation is as follows:
Here A = mass number which is equal to the total number of protons + number of neutrons, Z = atomic number of any element which is also indicates Number of protons or number of electrons in the given atom.
Answer to Problem 39QAP
The number of protons, neutron and electron in
Explanation of Solution
Given Information:
The given atomic symbol is as follows:
Calculation:
Comparing the given atomic symbol with the following:
Z = atomic number of any element = Number of protons or number of electrons in the given atom
Thus, atomic number = 56
Also, number of protons = number of electrons = 56
A = mass number which is equal to the total number of protons + number of neutrons
Therefore,
(b)
Interpretation:
Determine the number of protons, neutron and electron in the given atom.

Answer to Problem 39QAP
The number of protons, neutron and electron in
Explanation of Solution
Given Information:
Calculation:
Z = atomic number of any element = Number of protons or number of electrons in the given atom
Atomic number = 22
Therefore;
Number of protons = number of electrons = 22
A = mass number which is equal to the total number of protons + number of neutrons
Therefore,
(d)
Interpretation:
Determine the number of protons, neutron and electron in the given atom.
