What is the role of electrons in chemical reactions?

Electrons play a crucial role in chemical reactions by participating in bond formation and breaking. They determine how atoms interact.

Can you explain how electrons affect the reactivity of elements?

Certainly! The number of valence electrons in an atom influences its reactivity. Atoms with nearly full or nearly empty outer shells tend to react more readily.

What happens to electrons during a redox reaction?

In a redox reaction, electrons are transferred between atoms. One atom loses electrons (oxidation) while another gains them (reduction).

How do electrons influence the formation of ionic and covalent bonds?

Electrons determine bond types: ionic bonds form when electrons are transferred, while covalent bonds form when electrons are shared between atoms.

Can you give an example of a chemical reaction involving electron transfer?

Sure! A classic example is the reaction between sodium and chlorine, where sodium donates an electron to chlorine, forming NaCl.
