higher is the no of shared pairs of electrons higher will be the bond dissociation energy.
The quantum number of the highest occupied electron orbital in a Bohr model atom corresponds to the atom's period (row) number in the periodic table.
we know that metal has tendency to lose a electron more easily than non metals so the value of the first ionization energy of the metals is very small.
Electrons in the outer most energy level is called "valence electrons." Groups are the columns of the periodic table. The more valence electrons (up to 8), the closer to the right. The number of electrons needed to make an atom stable is 8. (Minus Hydrogen and Helium, which only need 2 electrons to be stable.)
The mass defect represents the mass converted to binding energy
Electrons gain energy by interacting with the electromagnetic spectrum, such as through light. A photon will make contact with an electron and deliver a transfer of energy which can move it to a higher energy state (this is usually referred to as exciting an electron). Electrons move between their energy states in fixed steps. So, if one is in the lowest energy state (ground state) and is then excited by a photon, it will instantly move to the next highest energy state until it transfers this energy to something else or out of the system (if you are assuming an open system). In a closed system, the energy would be conserved and without any additional interaction, an excited electron will remain excited until it can transfer the energy to something else. May need someone more adept at physics to elaborate.
the group number shows the number of electrons in the outermost energy levels. forexample sodium (Na) have 1 electron in the outermost shell and is placed in the group 1. Elements are grouped in rows depending on their energy levels, or valence electron numbers. Columns of elements are those that are chemically similar, or react
Transition means switching from one energy level to another; the lost energy turns into photons.
The energy required to remove more than one electron from atoms.
The ionization energy is the energy needed to extract an electron from an atom.The value of the ionization energy increase from left to right in a period of the periodic table and decrease in a group from the above to down.
The brighter the light the more energy is being released, which may alter the arrangement and quantity of electrons in the outer shells within an atom's electron configuration. Dr. Koehler
Because if the radius is big, then the large distance affects the strenght of the electron with the nucleus. This also increases reactivity in non metals since it will be easier to take away the electron :)

Quantum numbers relate to electrons in that they denote the electrons angular momentum. Angular momentum is a vector, so it has a magnitude (1/2) and a direction (+ or -). Each orbital in an atom can only hold 2 electrons, and each electron will have a +1/2 spin and a -1/2 spin.
The quantum number of the highest occupied electron orbital in a Bohr model atom corresponds to the atom's period (row) number in the periodic table.
Elements whose atoms have the same number of outer electrons have similar properties..
