What can acid rain do to buildings and statues

The chemicals that acid rain contains can have damaging effects on objects like buildings, monuments, statues, and cars.

Its components can make paint to be peel, stone construction appears old, worn down which reduces the architectural value and beauty.

Depending on how acidic the rain is, it can obliterate these constructions to a brutal degree.

First, components like sulfurous, sulfuric and nitric acids mix with air and rain. Then they react with calcite or calcium-based compounds in marble and limestone and dissolve calcite. 

The dry depositions of acidic particles contribute severely to the corrosion of construction materials, building paints, stones like marble, limestones and various type of granites.

Acid rains aggravate the life value of buildings and architectural structures.

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms
