Answer:
i) Neon (Ne)
ii) Fluoride Ion (F⁻¹)
iii) Oxide Ion (O⁻²)
Explanation:
Ions are those charged species which are either positively charged (by loosing electrons) called as cations or negatively charged (by gaining electrons) called as anions.
In given examples, Neon is a neutral atom which has an atomic number 10. It contains 10 electrons in its neutral state with the electronic configuration 1s², 2s², 2p⁶.
Fluorine atom has an atomic number of 9. Therefore, it contains 9 electrons in its neutral state with an electronic configuration of 1s², 2s², 2p⁵. When Fluorine atom gains one electron it gets 10 electrons with electronic configuration of 1s², 2s², 2p⁶.
Oxygen atom has an atomic number of 8. Therefore, it contains 8 electrons in its neutral state with an electronic configuration of 1s², 2s², 2p⁴. When Oxygen atom gains two electron it gets 10 electrons with electronic configuration of 1s², 2s², 2p⁶ forming an Oxide Ion.

<h3>Answer</h3>
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.
<h2>Explanation</h2>
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.
