Front

What is the significance of the octet rule in chemistry?

Back

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of 8 electrons, leading to greater stability.

Front

What is the role of neutrons in an atom?

Back

Neutrons contribute to the mass of an atom and help stabilize the nucleus by offsetting the repulsive forces between protons.

Front

How do ionic bonds form between atoms?

Back

Ionic bonds form when one atom donates an electron to another atom, resulting in the formation of positively and negatively charged ions that attract each other.

Front

What is the difference between an atom and an ion?

Back

An atom is a neutral particle with an equal number of protons and electrons, while an ion is a charged particle that has either lost or gained electrons.
