Question

How are ions formed? by the disintegration of one or more electrons by the sharing of one or more electrons between two atoms by the transfer of one or more electrons from one atom to another by the disintegration of one or more protons

Answer 1

Answer: The correct answer is by the transfer of one or more electrons from one atom to another.

Explanation:

Ions are the charged species that are formed when electrons get added up or are lost from an atom.

If an atom looses electrons, it will lead to the formation of positively charged ion known as cation.

If an atom gains electrons, it will lead to the formation of negatively charged ion known as anion.

Ions are also formed when an atom transfers its electrons to another atom. In this way, the atom which is donating electron will attain positive charge and the ion which is accepting electrons, will attain negative charge.

Thus, the correct answer is by the transfer of one or more electrons from one atom to another.

Answer 2

By the transfer of one or more electrons from one atom to another

for example,
2Na + Cl₂ → 2Na⁺Cl⁻

Na - e⁻ → Na⁺
Cl₂ + 2e⁻ → 2Cl⁻
