Which chemical symbols in row 4 of the periodic table do not match up with their element names?

The periodic table is shown.
The chemicals in row 4 are K potassium, Ca calcium, Sc scandium, Ti titanium, V vanadium, Cr chromium, Mn manganese, Fe iron, Co cobalt, Ni nickel, Cu copper, Zn zinc, Ga gallium, Ge germanium, As arsenic, Se selenium, Br bromine, and Kr krypton.

In row 4 of the periodic table, the chemical symbols that do not match their element names are correctly identified as follows:

  • K (potassium) - This is correct.
  • Ni (nickel) - This is correct.
  • As (arsenic) - This is correct.

By checking the list again, it looks like these three do indeed match their element names. Other symbols that also match their respective names include Ca (calcium), Sc (scandium), Ti (titanium), V (vanadium), Cr (chromium), Mn (manganese), Fe (iron), Co (cobalt), Cu (copper), Zn (zinc), Ga (gallium), Ge (germanium), Se (selenium), Br (bromine), and Kr (krypton).

After reviewing the options you've provided:

  • K, Ni, As - All correctly match their element names.
  • K, Cr, Zn - All correctly match their element names.
  • K, Fe, Cu - All correctly match their element names.
  • K, Mn, Kr - All correctly match their element names.

It looks like none of the options provided contain elements whose symbols do not match their names, so no symbols in row 4 of the periodic table from the options provided do not match their element names.

If there is a specific focus on alternative naming conventions that might have been intended here, please clarify. However, based on standard nomenclature as it stands, all symbols in the row correctly match their names in conventional chemistry terminology. Therefore, if answering based purely on your options, it seems all the provided pairs are correct.
