12 Questions
What are the two basic particles that make up the hydrogen atom?
Proton and electron
What is the charge of the proton?
Positively charged
What particle in the atom is slightly heavier than the proton and has no electrical charge?
Neutron
In all neutral atoms, what is the relationship between the number of electrons and the number of protons?
Equal
What is the mass relationship between the electron, proton, and neutron?
Proton (or neutron) mass is approximately 1836 times that of the electron
What is the order of magnitude of the radii of the proton, neutron, and electron?
2 x 10^-15 m
What determines the maximum number of electrons that can be in each shell of an atom?
The equation $2n^2$, where $n$ is the shell number.
What determines the force of attraction or repulsion between two charged bodies?
Coulomb's law
Why do electrons in an atom repel each other?
Because like charges repel each other.
What happens to the binding force between the nucleus and the orbital electrons as the distance increases?
The binding force diminishes.
Why are electrons more readily removed from atoms with incomplete outer subshells?
Due to weaker binding forces and lower energy required.
What property of the atom allows for the removal of electrons more easily?
Incomplete outer subshells and few electrons.
This quiz covers the fundamental concepts of current and voltage by exploring the basic structure of atoms, particularly focusing on the hydrogen atom. Learn about the roles of protons and electrons within an atom and how they contribute to electrical phenomena.
