O. c. yes. Covalent, Polar Covalent, and Ionic Bonds. When two bonded atoms attract electrons with equal strength, the result is a nonpolar covalent bond. A polar covalent bond is one in which the electrons are unequally shared between the atoms. An ionic bond results when the sharing is so unequal that fully charged ions form.

WebbSo once again for protons, we look at the atomic number, that's 92. So there must be 92 protons. In a neutral atom, the number of electrons is equal to the number of protons. So there are 92 electrons and then finally, to figure out the number of neutrons, we subtract this number from the mass number. So we just need to do 235 minus 92.
