It is assigned the chemical symbol U. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons. The uranium nucleus binds between 141 and 146 neutrons, establishing six isotopes (U-233 through U-238), the most common of which are uranium-238 (146 neutrons) and uranium-235 (143 neutrons).

The atomic number for argon is 18. The atomic number is the number of protons in the nuclei of the atoms of an element. So argon has 18 positively charged protons, and a neutral argon atom will also have 18 negatively charged electrons. ... The unabbreviated electron configuration for argon is 1s22s22p63s23p6 .
