Explanation:
J.J. Thomson's experiments with cathode ray tubes showed that all atoms contain tiny negatively charged subatomic particles or electrons. Thomson proposed the plum pudding model of the atom, which had negatively-charged electrons embedded within a positively-charged soup
Answer:
b)The molar mass of the particles.
Explanation:
The rate of effusion of a gas is inversely proportional to the square root of its molar mass (Graham's law), a relationship that closely approximates the rate of diffusion. As a result, light gases tend to diffuse and effuse much more rapidly than heavier gases.
Answer:
(<em>n</em> = 7) ⟶ (<em>n</em> = 4)
Explanation:
1. Convert the energy to <em>joules per mole of electrons</em>.
<em>E</em> = 55.1 × 1000 = 55 100 J/mol
2. Convert the energy to <em>joules per electron
</em>
<em>E</em> = 55 100/(6.022 × 10²³)
<em>E</em> = 9.150 × 10⁻²⁰ J/electron
3. Use the Rydberg equation to <em>calculate the transition
</em>
Rydberg's original formula was in terms of wavelengths, but we can rewrite it to have the units of energy. The formula then becomes

where
= the Rydberg constant = 2.178 × 10⁻¹⁸ J
and
are the initial and final energy levels.
