Answer 2

Hey dear,

● Class A metals & Hard acids-
- Those metals that can form hard acids are called class A metals.
- Hard acids are those with relatively strong ionic bonds.
- These metals are more likely to be associated with fluorine than iodine.
- E.g. sodium, calcium, aluminium, iron, titanium, etc.
- They usually target phospholipid, ATP, nucleic acids, etc.

Hope this helps you...
