The cause of polarity of a covalent bond is the difference in electronegativity between the atoms being bonded. The more electronegative atom involved in the bond attracts the electrons more than the less electronegative. If you want to know the reason for electronegativity then follow the link.
The minimum concentration of the precipitating agent required to cause precipitation of the cation in solution will depend on the solubility product constant (Ksp) of the cation's salt. The concentration of the precipitating agent must be sufficient to exceed the solubility product constant and drive the reaction towards precipitation. To determine the exact concentration needed, you would need to know the Ksp value for the cation's salt.
it causes the atoms to lose their negative electrons
When a few atoms undergo fission, they cause many more atoms to split; this process is called an atomic bomb.
The arrangement of atoms in a mineral sample can cause the formation of crystals.
Cations are smaller than their corresponding atoms because they lose electrons, leading to a decrease in electron-electron repulsions which causes the remaining electrons to be pulled closer to the nucleus, making the cation smaller. Anions are larger than their corresponding atoms because they gain electrons, resulting in increased electron-electron repulsions that cause the outer electron shell to expand, making the anion larger.

C-F bonds are polar since there is a difference in electronegativity between carbon and fluorine atoms which results in an uneven distribution of electron density. They are not ionic because the electronegativity difference between carbon and fluorine is not large enough to cause a full transfer of electrons from one atom to another.
The more electronegative an atom is the more "pull" the atom will have on the electrons in the molecules. For example, water (H2O) contains the very electronegative atom Oxygen. Oxygen would pull more electrons toward it so the hydrogen would essentially lose their electrons. The dipole moment would point towards the oxygen. Therefore, the more electronegative an atom is the more the dipole moment will point in its direction therefore affecting polarity of the bond.

An ionic bond forms when one atom transfers electrons to another atom, resulting in the formation of positively and negatively charged ions. The attraction between these oppositely charged ions leads to the formation of a strong bond, known as an ionic bond.

Ammonia (NH3) is a covalent compound. It forms covalent bonds between the nitrogen and hydrogen atoms through the sharing of electrons.
