Which statement is correct?
A) The probability of finding an electron near the nucleus is very
low.
B) An electron can be located all the time within an orbital.
C) The probability of finding an electron near the nucleus is very
high.
D) An orbital is a circular path around which electrons revolve
round the nucleus.
*Please include explanations for why each statement is
correct/incorrect? Thanks!
(c) is correct option
As near the nucleus 1s orbital is there and rhe shape of s orbital is spherical so it has symmetrical probability near the nucleus
B is incorrect because electron revolve in orbitals in different orientation.so we can't locate an electrons as it we can know only probably of electron
D is incorrect because orbital may be circular, dumb bell and double dumb bell shape.

Consider an electron within the ls orbital of a hydrogen atom. The normalized probability of finding the electron within a sphere of a radius R centered at the nucleus is given by normalized probability = [az-e * (až + 2a, R+ 2R)] where a, is the Bohr radius. For a hydrogen atom, ao = 0.529 Å. What is the probability of finding an electron within one Bohr radius of the nucleus? normalized probability: 0.323 Why is the probability of finding...
Question 18 3 pts For the electronic transitions shown below (respectively left to right), an electron would n=3 Energy n=2 n=1 None of these answers makes any sense in relation to the diagram shown. absorb a photon and be stabilized; absorb light and be destabilized. emits a photon and relaxes; absorb a photon and be stabilized. 0 Neither transition show is quantized. absorb energy and becomes excited; emits a photon as it falls back to a lower potential energy level....
Select true or false for each statement below. True False Electron states are described by orbits, which indicate exactly where an electron is located in an atom. True False The energy levels of all atoms except hydrogen are quantized. True False Electrons move in elliptical orbits around the nucleus of an atom. True False Atoms can gain energy by absorbing a photon. True False When atoms are in an excited state, they can release this energy by emitting light.
Which statement about the wave function for a single electron is NOT correct? 1- Louis de Broglie postulated that the wavelength of an electron is given in terms of Planck's constant and its momentum, λ = h / p. 2- A French graduate student named Louis de Broglie first had the idea that an electron should be described as a wave. 3-The amplitude of a wave function at a particular point in space equals the probability density of finding the...

Which of the following is correct? a) The rotation axes of planets are always perpendicular to their orbital plane (the ecliptic). b) No planet's orbital inclination is more than 20 degrees from the ecliptic. c) Planets orbits are circular. d) Planets always rotate and revolve in the same direction. 11. Which of the following is not a real difference between asteroids and comets? a) Asteroids are made mostly of rock and comets are made mostly...
Microbiology In the competitive inhibition of enzyme activity, which statement is correct? Inhibitor directly competes with the substrate. Less substrates must be added in order to reach Vmax. The number of active sites is unlimited. None of the above. In the noncompetitive inhibition of enzyme activity, which statement is correct?Inhibitors will cause a conformational change in the enzyme, more substrate must be added to reach Vmax, Enzymes bound to the inhibitor can still bind substrate, none of the above. ....
