Q. 4.94 - An Introduction to General, Organic, and Biological Chemistry

Question

Indicate if each of the following statements is true or false:  $(4.3)$

a. The neutron is electrically neutral.

b. Most of the mass of an atom is due to the protons and neutrons.

c. The charge of an electron is equal, but opposite, to the charge of a neutron.

d. The proton and the electron have about the same mass.

e. The mass number is the number of protons.

Step-by-Step Solution

Answer

a. The statement is true.

b. The statement is true. 

c. The statement is false.

d. The statement is false.

e. The statement is false.

Part (a) step 1: Given Information

We need to find the statement is the neutron is electrically neutral is true or false.

Part (a) step 2: Explanation

The neutron is neutrally electrically.  

It is a true statement.

Part (b) step 1: Given Information

We need to find the statement is most of the mass of an atom is due to the protons and neutrons.  is true or false. 

Part (b) step 2: Explanation

Most of the mass of an atom is due to the neutrons and protons.

It is a true statement.

Part (c) step 1: Given Information

We need to find the statement is the charge of an electron is equal but opposite, and the charge of a neutron is true or false. 

Part (c) step 2: Explanation

The charge of an electron is equal, to but opposite, to the charge of a neutron 

It is a false statement.

A neutron is a neutral particle and an electron is negatively charged subatomic particle.

Part (d) step 1: Given Information

We need to find the statement is the proton and the electron have about the same mass is true or false. 

Part (d) step 2: Explanation

The electron and the proton have about the same mass.

It is a false statement.

Part (e) step 1: Given Information

We need to find the statement is the mass number is the number of protons is true or false. 

Part (e) step 2: Explanation

The number of protons is the mass number.

It is a false statement.

Because the number of protons is the atomic number.
