The model has resulted into a formula called the Rydberg formula. It also came about from the electron transfer within the hydrogen atom. The formula is shown in the picture, where RH is the Rydberg constant and λ is the wavelength . Thus, the solution is as follows:
1/λ = (1.0973731×10⁷ m⁻¹)(1/2² - 1/3²)
Solving for λ,
<em>λ = 6.56×10⁻⁷ m</em>
Potassium should have largest atomic radius.......
'cause on moving to right, attractive force between nucleus and electrons increases and causes shielding effect, due to which atomic radius get smaller
The heat energy required to change a unit mass of a solid into a liquid at constant temperature is called thermal equilibrium.
'Equilibrium' means balance, and thermal is used to define temperature.
The moles of ammonia in 1.20 x10^25 molecules of ammonia is calculated as follows
by use of Avogadro constant
1moles = 6.02 x10^23
what about 1.20 x10^25 moles
by use of cross multiplication
= 1 mole x ( 1.20 x10^25) /( 6.02 x10^23) = 19.93 moles
