Question

chemistry Q 7 Does the part of the atom referred to in part (a) take up a large or a small percentage of the space in an atom? Fill in the blanks. Light is a form of Light has wave properties. A beam of light can be described as a series of vibrating electric and magnetic fields called radiation. The distance between two wave crests (peaks) is called the of the wave. The rate at which waves oscillate is called the of the wave. Light also has particle properties. A beam of light consists of particles/parcels of energy called quanta or The higher the frequency of light, the is its energy. According to the planetary model of atomic structure proposed by Niels Bohr, the electrons in an atom orbit the nucleus. Can an electron orbit at any distance from the nucleus or can it only orbit at certain distances? According to the Bohr model, can an electron in an atom have any possible energy or is its energy restricted to certain values only (i.e. it's quantized)? When does an electron in an atom have higher energy, when it's closer to or farther from the nucleus? When energy is added to an atom, it emits light. The collection of light frequencies that the atom emits is called an atomic spectrum. Do atomic spectra contain all possible frequencies or just a limited number of frequencies? To the same depth as the textbook, describe how Bohr's planetary model explains the nature of atomic spectra (i.e. your answer to part (d)).

Explanation / Answer

6)a)energy
b)electromagnetic
c)wavelength, frequency
d)photons
e)higher(since energy =h*frequency)

7)a) It can orbit at only certain distance since the energy of an electron is quantised and hence, it can revolve around the nucleus only at certain distances)
b)He stated that it is quantised.
c)it has higher energy when it is away from the nucleus since it will be less stable.
d)They contain limited number of frequency since the electrons are ejected by light of only specific frequencies.
e)I do not have the textbook (name not known)
