To say an object has a negative charge is to say it has an excess of what kind of charges? A) Either protons or electrons.B) Electrons.C) Protons.D) None of these
You have to be kidding. What is the charge on each of these particles?
To determine which answer is correct, we need to understand the concept of charges in atoms. Atoms are made up of protons, neutrons, and electrons. Protons have a positive charge, electrons have a negative charge, and neutrons have no charge.
When an object has a positive charge, it means it has an excess of protons compared to electrons. On the other hand, when an object has a negative charge, it means it has an excess of electrons compared to protons.
Now, let's examine the given options:
A) Either protons or electrons: This option is not entirely accurate, as a negative charge specifically indicates an excess of electrons, not protons.
B) Electrons: This option correctly states that an object with a negative charge has an excess of electrons, making it the most appropriate choice.
C) Protons: This option is incorrect. Protons have a positive charge and are not associated with a negative charge.
D) None of these: This option is incorrect as option B, "Electrons," correctly represents an object with a negative charge having an excess of electrons.
Therefore, the correct answer is B) Electrons.
