Hydration Energy Increases Significantly By Moving From Left To Right In A Period As The Charge To Size Ratio Increases.
Larger the atomic size lesser the hydration energy or the energy decreases. As the atomic sizes decrease from left to right in a periodic table therefore the heat of hydration increases from left to right. Same is the case with p-block elements .
Anion will have more electron than which atom it was form. So, after forming the the atom will have more electron cloud and size will be smaller compare to the original one.
it means increase i the size of shale due to hydration.
Lattice energy is directly related to the size of the ions bonded. Smaller ions generally have a more negative value for lattice energy because the nucleus is closer to and thus has more attraction for the valence electrons.
Heat of hydration or enthalpy of hydration of ions corresponds to the heat that is released by hydration of one mole of ions at a constant pressure. The more the ion is hydrated, the more heat is released. Degree of hydration depends on the size and charge of ion. The smaller the ion and the greater its charge, it will be the more hydrated.

No. It doesn't change size.
Group Two elements form oxide consisting of ionic bonds. With that in mind, as you go down group two, the ionic radius increases due to an addtion of a electron shell, so therefore, melting point of group2 oxide decreases down group because the distance between the O2- and Group two ion are further apart. The increase of bond length results in less energy needed to break the ionic bonds, resulting in decrease of energy.
Well the difference will be in the type of bond formed as a result. The bond would be Ionic in case of polarized anion and Covalent in case or unpolarised anion.The related link below also talks about the size of the anion and charge density in determining the bond type.
A cation is smaller than the neutral atom because one electron is removed from the original atom to form it. An anion is larger than the neutral atom because one electron is added to the original atom to form it.
Because of high of heat of Hydration of HF ( Fluoride ion is extensively hydrated because of it's small size )
Lattice energy is directly related to the size of the ions bonded. Smaller ions generally have a more negative value for lattice energy because the nucleus is closer to and thus has more attraction for the valence electrons.
No, the size of the particles does not change. What does increase, however, is the speed of the particles and the amount of energy they each contain.
