Steel is the most commonly used metallic material. However, its annual loss due to corrosion is huge. Preventing metal corrosion

is a big issue in scientific research. The wrong description about metal corrosion below is
A. Steel corrodes more easily in
humid air than in dry air
B. Steel corrosion in reality is the
chemical change that takes place
when steel reacts with the
oxygen and water vapour in air.
C. Aluminium is more active than
the iron in steel. Therefore its
ability to resist corrosion is
weaker than steel.
D. Painting on the surface of steel
can prevent corrosion of the
steel.​

The electron affinity of an element is positive if energy is absorbed during the process of accepting an electron and negative i
julsineya [31]

Answer:

See explanation

Explanation:

Electron affinity is the energy released when an extra electron is added to a neutral gaseous atom. A negative value of electron affinity indicates that energy is given out and vice versa.

Metals have positive electron affinity since electrons rarely accept electrons, so;

Na(g)+ 1e^- → Na^-(g)      positive

Mg(g)+1e^- → Mg^-(g)      positive

For the last case; Br(g)+ 1e^- → Br^-(g), the electron affinity for the non-metals is negative. hence the answer
