On the Differentiation of Polarity of Matter
On the world of matter, there are polarity differences. Today, taking potassium fluoride (KF) as the analysis, its polarity or not.

The judgment of polarity of the husband is related to the distribution of charge in the molecule. Potassium fluoride is also an ionic compound. Potassium (K) is a metallic element, which is active and prone to electron loss; fluorine (F) is a non-metallic element, which is highly electronegative and easy to obtain electrons. When the two combine, potassium loses one electron to fluoride, and then forms potassium ion (K <) and fluoride ion (F <). In

ionic compounds, anions and cations are linked with electrostatic attractive forces to form a lattice structure. In this structure, the charge distribution is significantly uneven. The interaction between ions is strong, which is different from the molecular structure formed by the common electron pair in covalent compounds. Covalent molecules are non-polar if the charge distribution is uniform and the electron cloud is symmetrical; if they are uneven, they are polar.

And potassium fluoride is formed by ionic bonds, and the charges of anions and cations are concentrated, unlike the electron cloud distribution of covalent molecules. The uneven distribution of its charge is obvious, so potassium fluoride shows polarity.

The view of all things is clear in the structure and the distribution of charges, so the polarity can be distinguished. It can be seen from the principles of chemistry.
