1. An atom has a diameter of 1.50 Å and the nucleus of that atom has a diameter of 9.00 × 10^− 5 Å . Determine the fraction of the volume of the atom that is taken up by the nucleus. Assume the atom and the nucleus are a sphere. 2. Calculate the density of a proton, given that the mass of a proton is 1.0073 amu and the diameter of a proton is 1.69 × 10^ − 15 m...
An electron is trapped within a sphere whose diameter is 6.80 × 10 − 15 m (about the size of the nucleus of a medium sized atom). What is the minimum uncertainty in the electron's momentum?
The nucleus of the hydrogen atom has a radius of about 1.0 × 10-15 m. The electron is at a distance of about 5.29 × 10-11 m from the nucleus. Assuming the hydrogen atom is a sphere with a radius of 5.29 × 10-11 m, find (a) the volume of the atom, (b) the volume of the nucleus, and (c) the percentage of the volume of the atom that is occupied by the nucleus.
The uncertainty in position of a proton confined to the nucleus of an atom is roughly the diameter of the nucleus. If this diameter is 7.7
10) A molecule of roughly spherical shape has a mass of 1.80 x 10-25 kg and a diameter of 0.6 nm. If the uncertainty in the measured position of the molecule is equal to the molecular diameter, what is the minimum uncertainty in the speed of the molecule? (h=6.626 x 10-34 J •s) (5 points) A) 0.1 m/s B) 0.01 m/s C) 10 m/s D) 100 m/s E) 1 m/s
The nucleus of a hydrogen atom is a single proton, which has a radius of about 1.1 10-15 m. The single electron in a hydrogen atom normally orbits the nucleus at a distance of 5.5 10-11 m. What is the ratio of the density of the hydrogen nucleus to the density of the complete hydrogen atom?
A proton is fired from far away toward the nucleus of a mercury atom. Mercury is element number 80, and the diameter of the nucleus is 14.0 fm. If the proton is fired at a speed of 3.2 times 10^7 m/s, what is its closest approach to the surface of the nucleus? Assume the nucleus remains at rest. Express your answer to two significant figures and include the appropriate units.
A proton is fired from far away toward the nucleus of a mercury atom. Mercury is element number 80, and the diameter of the nucleus is 14.0 fm. If the proton is fired at a speed of 4.6×107 m/s , what is its closest approach to the surface of the nucleus? Assume the nucleus remains at rest.
15. The planetary model of the atom pictures electrons orbiting the atomic nucleus much as planets orbit the Sun. In this model you can view hydrogen, the simplest atom, as having a single electron in a circular orbit 1.06xl diameter. (a) If the average speed of the electron in this orbit is known to be 2.20x10° m/s, calculate the number of revolutions per second it makes about the nucleus. (b) What is the electron's average velocity? 0-10 m in
A proton is fired from far away toward the nucleus of a mercury atom. Mercury is element number 80, and the diameter of the nucleus is 14.0 fm If the proton is fired at a speed of 3.2×107 m/s , what is its closest approach to the surface of the nucleus? Assume the nucleus remains at rest. Express your answer to two significant figures and include the appropriate units.(Hint: The charge of the Mercury nucleus is +80e)
