What is the total charge of the uranium nucleus? (The neutral uranium atom has 92 electrons.) 1.47x10-17 c Computer's answer now shown above. You are correct. Previous Tries Your receipt no. is What is the magnitude of the force on an electron at a distance of 7.61 angstrom from the uranium nucleus?

number protons and force are Q = 1,472 10⁻¹⁷ C F = 3,656 10⁻⁸ N

Explanation:

Atoms are neutral whereby the number of electrons in the atom is compensated by an equal number of positively charged protons in the nucleus, so there are 92 protons, the total charge can be found by a rule of proportions

Q = # proton * 1.6 10⁻¹⁹C

Q = 92 * 1.6 10⁻¹⁹

Q = 1,472 10⁻¹⁷ C

To calculate the force of an electron we use Coulomb's law

F = k q1 Q / r²

F = k e Q / r²

The Coulomb constante is 8.99 10⁹ N m² / C²

F = 8.99 10⁹ 1.6 10⁻¹⁹ 1,472 10⁻¹⁷ / (7.61 10⁻¹⁰) ²

F = 3,656 10⁻⁸ N

This force is attractive.
