As the number of electrons added to the same principal energy level increases, atomic size generally
C. Decreases.
0 degrees Celsius and 1 atmosphere.
Answer:
Transition from n = 4 to n = 1 corresponds to shortest wavelength.
Explanation:
Process
A 0.9375
B 0.75
C 0.0421
D 0.1875
According to Rydberg equation for electronic transition in H-like atoms:
where, is wavelength of light emitted or absorbed, is Rydberg constant.
So, higher the value of , lower will the corresponding wavelength of light.
Hence process A will be associated with shortest wavelength.
Answer:
22.95g
Explanation:
Given parameters:
Percentage by mass of silver in silver iodide = 45.9%
Mass of silver iodide given = 50g
Unknown:
Mass of silver in silver iodide = ?
Solution:
The formula of the compound is;
Silver iodide = AgI
Since the percentage by mass of silver in the compound is 45.9%;
Mass of silver = percentage by mass of silver x mass of AgI
Mass of silver = x 50 = 22.95g
Answer:
How do atoms give off light?
Atoms emit light when they are heated or excited at high energy levels. The color of light that is emitted by an atom depends on how much energy the electron releases as it moves down different energy levels. ... It shows the electron moving down energy levels.
