Answer 1

In the fourth row of the periodic table, the chemical symbols that do not match their element names are:

- K (Potassium) - correct
- Ca (Calcium) - correct
- Sc (Scandium) - correct
- Ti (Titanium) - correct
- V (Vanadium) - correct
- Cr (Chromium) - correct
- Mn (Manganese) - correct
- Fe (Iron) - not matching (symbol Fe, name Iron)
- Co (Cobalt) - correct
- Ni (Nickel) - correct
- Cu (Copper) - not matching (symbol Cu, name Copper)
- Zn (Zinc) - correct
- Ga (Gallium) - correct
- Ge (Germanium) - correct
- As (Arsenic) - correct
- Se (Selenium) - correct
- Br (Bromine) - correct
- Kr (Krypton) - correct

So, the correct answer is:

**K, Fe, Cu**
