Which statement about subatomic particles is not true?
A
Neutrons have no charge and are found in the nucleus.
B
Electrons have a negative charge and are found in the nucleus.
C
The mass of a neutron is approximately equal to the mass of a proton.
D
Protons have a positive charge and are found in the nucleus.
Verified step by step guidance1
Identify the subatomic particles involved: protons, neutrons, and electrons.
Understand the location of each particle: Protons and neutrons are located in the nucleus, while electrons are found in the electron cloud surrounding the nucleus.
Review the charge of each particle: Protons have a positive charge, neutrons have no charge, and electrons have a negative charge.
Compare the mass of protons and neutrons: Both have similar masses, which are significantly larger than the mass of electrons.
Evaluate the statement about electrons: Electrons are not found in the nucleus; they are located in the electron cloud, which makes the statement 'Electrons have a negative charge and are found in the nucleus' incorrect.
