Question

Ions are atoms that have gained or lost which subatomic particles?


A.protons


B.neutrons
C. electrons

Answer 1

Answer: The correct answer is Option C.

Step-by-step explanation:

There are 3 subatomic particles present in an atom. They are: protons, electrons and neutrons.

• Protons: They carry positive charger and are found in nucleus.
• Electrons: They carry negative charge and are found around the nucleus.
• Neutrons: They dos not carry any charge and are found in nucleus.

An ion is formed when an atom looses or gains electron.

• When an atom looses electrons, it will form a positive ion known as cation.
• When an atom gains electrons, it will form a negative ion known as anion.

Hence, the correct answer is Option C.

Answer 2

Protons cannot be lost without the atoms becoming an entirely different element. Elements can infact have different numbers of neutrons within the same element, but neutrons are not related to the electrical charge. The answer is c. electrons.
