Answer:
601 nm
Explanation:
Energy of photon having wavelength of λ nm
=
eV
Energy of 249 nm photon
=
=4.996 eV
Similarly energy of 425nm photon
=
=2.927 eV
Difference = 2.069 eV.
This energy will give rise to another photon whose wavelength will be
λ = 
= 601 nm.
By looking at each ones texture. and maybe even color
Your answer is c. electrons that are available for bonding.
Explanation:
The inner part of earth is mainly of two parts
- Mantal
- Core
Mantal and core both consists of Hot magmas .
So volcanism is required
Answer:
1, their atoms have the same number of valence electron. because valence electron determine the group of elements.
