'How many valence electrons does each of the following atoms have? a, titanium, Z = 22 b. iodine, Z = 53 radium, Z = 88 d. manganese, Z = 25'
Added by Audrey S.
Step 1
Titanium (Ti) has an atomic number (Z) of 22. Its electron configuration is [Ar] 4s² 3d². The valence electrons are the electrons in the outermost shell, which are the 4s² electrons. So, titanium has 2 valence electrons. b. Iodine (I) has an atomic number (Z) of Show more…
