Assertion: hydrogen atom's nucleus | /r/HasAspect | positive charge
Facets:
value: always
type: TEMPORAL
value: thus, [latex]v=\frac{kzq_e}{r_n}\\[/latex]
type: OTHER
Source sentences:
text: The nucleus has a positive charge Zq e ; thus, [latex]V=\frac{kZq_e}{r_n}\\[/latex], recalling an earlier equation for the potential due to a point charge.
text: Electrons have a negative charge and the nucleus always has a positive charge, so they attract each other.
