latice energy decreases as you move down a group. This is mostly due to the fact that, as you move down a group in the Periodic Table the atomic radius increases. It follows that since the square of the distance is inversely proportional to force of the attraction between charges (Coulomb's Law), latice energy will decrease as atomic radius increases.
Ionic charge and ionic radius affect lattice energy; the smaller the radius, the greater the lattice energy.
This interaction tends to lower the energy of the second electron, means that the force between the 2 electrons becomes attractive.
Ionic radius
Electrons in the outermost energy shell (valence shell) have the most energy.
Secondary electron images show morphology and topographyof a sample. The more the number of electrons reaching the detector, the brighter the image is. Back scattered electron images show difference in composition - or more exactly, difference in atomic number over a sample. The higher the atomic numbers of the atom, the more backscattered electrons are bounced back, making the image brighter for larger atoms.A second difference is back scattered electrons are produced by the elastic interaction of the beam electron with nuclei of atoms in the specimen. No energy is lost as it is elastic interaction. On the other hand secondary electrons are produced by inelastic interaction of beam electrons with electrons in the atom rather than the nucleus. Since it is inelastic interaction, there is energy loss.
The outermost electrons are called VALENCE electrons.
The energy is higher.
The energy is higher.
Lattice energy is energy required to separate ions to infinite distance with no more interaction. Cohesive energy is energy required to separate atoms to infinite distance with no more interaction.

Electrons are located in energy levels within the electron cloud.
In ionic bonding the electron rich species donates electron to the electron lacking species.in this process the electron donating species converts into cation by loosing electron and electron accepting species converts into anion by accepting electron.the ions now combine to from a ionic compound by releasing lattice energy
The outermost electrons are called VALENCE electrons.
The energy of electrons is expressed in eV (electron volts).
The energy is higher.
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.
Both atoms have separate electron configurations. The electron configuration for Na is: 1s^2 2s^2 2p^6 3s^1 The electron configuration for Cl is: 1s^2 2s^2 2p^6 3s^2 3p^5
Valence electrons are the highest energy electrons in an atom.
Valence electrons are the electrons in the outermost energy level.
