* Ionic Bond Formation: Bromine (Br) is a nonmetal with a high electronegativity (tendency to attract electrons), while potassium (K) is a metal with low electronegativity. When they react, bromine will strongly attract an electron from potassium. This transfer of an electron results in the formation of an ionic bond.
* Ion Formation:
* Potassium (K) loses an electron and becomes a positively charged ion called a potassium cation (K+).
* Bromine (Br) gains an electron and becomes a negatively charged ion called a bromide anion (Br-).
* Electrostatic Attraction: The oppositely charged ions (K+ and Br-) are now attracted to each other due to electrostatic forces. This attraction holds them together in an ionic compound.
* Formation of Potassium Bromide (KBr): The resulting ionic compound is potassium bromide (KBr). It's a white crystalline solid that is commonly used in medicine and photography.
In summary:
The bromine atom attracts an electron from the potassium atom, forming a potassium cation (K+) and a bromide anion (Br-). These ions are then held together by electrostatic forces, resulting in the formation of the ionic compound potassium bromide (KBr).
