Chapter 1, Problem 1RQ
What are the three principal parts of an atom, and what charge does each carry?
Expert Solution & Answer
To determine
The three principal parts of an atom and the charge that each one carries.
Answer to Problem 1RQ
The three principal parts of an atom are the proton, the electron and the neutron.
A proton carries a positive charge.
An electron carries a negative charge.
A neutron does not carry any charge.
Explanation of Solution
Description:
The basic building block of the universe is the Atom.
Any substance that has mass and occupies space is called matter and all matter is made from a combination of atoms.
An atom is made of three principal parts, they are: Proton, Electron and Neutron.
A proton carries a positive charge.
An electron carries a negative charge.
A neutron does not carry any charge.
Conclusion:
The three principal parts of an atom and the charge that each one carries respectively have been explained.
