How will you account for the polarisation of a covalent bond?
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.
Determine the minimum concentration of the precipitating agent on the right to cause precipitation of the cation from the solution on the left?
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.
What does heat cause atoms to do?
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?
When a few atoms undergo fission, they cause many more atoms to split; this process is called an atomic bomb.
What arrangement of atoms in a repeating pattern in a mineral causes the formation of?
The arrangement of atoms in a mineral sample can cause the formation of crystals.
Why are size of cations always smaller and size of anions always bigger than the corresponding atom?
anions always gain extra electrons casing the ionic radius to increase but cations remove electrons causing the ionic radius to decrease .therefore anionic radius is greater than cationic radius

What are the two parts of an ionic compound?
Ionic compounds are composed of positively charged ions, known as cations, and negatively charged ions, known as anions. The cations are typically metal atoms that have lost electrons to achieve a stable electron configuration, while the anions are typically nonmetal atoms that have gained electrons. The attraction between the oppositely charged ions results in the formation of a stable ionic compound.
Is C-F polar or ionic?
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.
How does elecronegativity affect the polarity of the bond between two atoms?
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.

What causes an ionic bond form?
A large difference in electronegativity values between the two atoms forming the bond will cause the bond to be ionic. The electrons from the less electronegative atom will be completely donated to the atom with the greater electronegativity. This occurs when a metal and a non metal bond.

What moves to cause an object to be hot?

The arrangement of atoms in a mineral sample can cause the formation of crystals.
Is ammonia a ionic or covalent compound?
Ammonia is a covalent compound. It is a compound of two nonmetals, nitrogen and hydrogen, so the difference in electronegativity is not great enough to cause ionic bonding.
