Answer:
The frequency of the photon that can dissociate dichlorine is 6.02×10¹⁴ Hz
Explanation:
The energy of a photon is given by the equation:
E=h·f
E=3.99×10⁻¹⁹ J/molecule
h (Planck's constant)=6.626×10⁻³⁴ m²·kg/s
∴ f=E/h
=6.02×10¹⁴ s⁻¹= 6.02×10¹⁴ Hz
Answer:
The new element will be thorium-226 (²²⁶Th).
Explanation:
The beta decay is given by:
Where:
A: is the mass number
Z: is the number of protons
β⁻: is a beta particle = electron
: is an antineutrino
The neutral atom has 88 electrons, so:
Hence the element is radium (Ra), it has A = 226.
If Ra undergoes 2 rounds of beta minus decay, we have:
Therefore, if a neutral atom with 88 electrons undergoes 2 rounds of beta minus decay the new element will be thorium-226 (²²⁶Th).
I hope it helps you!
