Why Be is not readily attacked by acids?

Answer:

Beryllium (Be) is not readily attacked by acids because of the presence of an oxide film on the surface of the metal.

Beryllium (Be)

Beryllium is an element with an atomic number of 4 in the periodic table. It is a bivalent and highly toxic element. The element has one of the highest melting points among the light metals. Beryllium exists in 30 different minerals, among which bertrandite, beryl, chrysoberyl, and phenacite are the most important.

A thin layer of oxide covers the surface of beryllium metal, which helps shield it from air attack.

2Be + O2 → 2BeO
