Answer:
The wavelength of the light emitted by a hydrogen atom for the given transition is 2166 nm.
Explanation:
The energy of nth energy levels of the H atom is given as:

Energy of the seventh energy level = 


Energy of the seventh energy level = 


Energy of the light emitted will be equal to the energy difference of the both levels.


Wavelength corresponding to energy E can be calculated by using Planck's equation:


The wavelength of the light emitted by a hydrogen atom for the given transition is 2166 nm.
These ions are disjoint by the charge on the ion into four dissimilar tables and listed alphabetically within each table. Each polyatomic ion, has it called, chemical, formula, two dimensional drawing, and three dimensional representation are given.
The three dimensional buildings are drawn as CPK models. CPK structures represent the atoms as sphere, where the radius of the sphere is equal to the van der waals radius of the atom; these buildings give a measure up the volume of the polyatomic atom.
B.) it is a complete organism
