Yes, everything in the universe according to M theory is in a state of change.
Malleability is a property of all metals.
by defining all metals would be wrong as synthetic metals would change the properties of the metal. in terms of natural metals or alloys, yes they are all conductors as their arrangements allow them to have delocalised electrons to carry electricity
No, it is not possible.
NOT all metals are magnetic
All metals are chemical elements.
All metals are elements.
all are non metals
All metals except alloys of metals are elements, but not all elements are metals.
Alchemist
You can reduce the air humidity is less oxidizing metals.
All are metals.
All metals are conductive. That is part of the definition of metals
