Answer #1

a. Electronegativity : An atom attracted the bond pair of electrons in a covalent bond is called electronegativity of an element.       H-->Cl

b. Ionization energy : The amount of energy is required to remove of an electron from an isolated gas atom is called Ionization energy.   M + IP-----> M+ + e-

c. Electron affinity: The amount of enery is released when an electron added to an isolated atom is called electron affinity.

    X + e- ------> X- =- EA

d. Atomic radius ; The distance between the center of neuclies and outer most shell is called atomic radius.

Each of the statements below attempts to explain why some periodic property varies predictably among elements in the periodic table. Determine if each statement is true or false. Within a family, elements with higher atomic numbers require less energy to remove an electron from the atom because the valance electrons are in lower principal energy levels. Within a family, elements with higher atomic numbers have atoms of smaller radius because the atoms have higher effective nuclear charge. Within a period,...
