The elements corresponding to the given electronic configuration are to be identified; the identified elements are to be arranged in the increasing order of their electronegativity value. Concept introduction: The number of electrons can be obtained from the electronic configuration of an element. The number of electrons is equal to the atomic number of the element. The element can be identified using the atomic number. Electronegativity can be defined as the measure of the tendency of an atom to attract the shared pair of electrons towards itself. To determine: The element corresponding to the given electron configurations and the correct arrangement of these elements in the increasing order of electronegativity.

1) How does the octet rule explain the formation of a chloride ion?
a) What noble gas is isoelectronic with the chloride ion?
b) Why are Group 17 (7A) elements found in many compounds but not group 18 (8A) elements?
An important starting material for the manufacture ofpolyphosphazenes is the cyclic molecule (NPCl₂)₃. The mol-ecule has a symmetrical six-membered ring of alternating N and P atoms, with the Cl atoms bonded to the P atoms. The nitrogen-phosphorus bond length is significantly less than that expectedfor an N−P single bond.(a) Draw a likely Lewis structure for the molecule.(b) How many lone pairs of electrons do the ring atoms have?(c) What is the order of the nitrogen-phosphorus bond?
