Answer:
a neutral atom doesn't have a charge and an ion does.
Explanation:
When atoms bond they can gain or lose electrons which gives them a charge.
anion = negatively charged ion
cation = positively charged ion
Answer:
D. gravitational potential energy
Explanation:
Answer:
F = ⅔ F₀
Explanation:
For this exercise we use Coulomb's law
F = k q₁q₂ / r²
let's use the subscript "o" for the initial conditions
F₀ = k q² / r²
now the charge changes q₁ = q₂ = 2q and the new distance is r = 3 r
we substitute
F = k 4q² / 9 r²
F = k q² r² 4/9
F = ⅔ F₀
