It requires using a mole ratio.
Answer: nucleons
Explanation:
The nucleons are the particles that constitue the nuclei of the atoms. Those are protons and neutrons.
They are not elementary particles (quarks are the elementary particles that form both protons and neutrons).
Protons are the particles that define the elements. Any different elements have different number of protons. H has one proton, He has 2 protons, Li has three protons, Na has 11 protons, U has 92 protons.
Protons are positively charged and the number of protons in any neutral atom is equal to the number of electrons (the electrons, which are elementary negatively charged particles, are around the nucleous).
Neutrons have not charge and are responsible for the stability of the nuclei. They are fundamental to avoid that the repulsion forces between the positively charged protons ends causing the collapse of the nuclei.
equation Fe3O4=Fe+CO2 is an impossible reaction
Explanation:
According to the Rydberg formula,
where, = wavelength
= Rydberg constant =
Z = atomic number (for He atomic number is 2)
= 4, = 8
Hence, putting the given values into the above formula as follows.
=
=
=
= 486 nm (as = 1 nm)
Thus, we can conclude that the Pickering series wavelength associated with the excited state is 486 nm.
