The protons, electron and neutrons should be given for the set of compounds. Concept introduction: Atom: Every atom is composed of a nucleus and one or more electrons bound to the nucleus. The nucleus is made of one or more protons and typically a similar number of neutrons. Isotope: Isotopes are variants of a particular chemical element which differ in neutron number whereas protons number is same. Isotopes are same atomic number but different in the mass number. The element symbol, atomic number and mass number can be written as follows, Z A X A is Mass number (The total number of protons and neutrons in an atom) and it is written in the superscript. Z is atomic number of the element and it is written in subscript. X is the symbol of the element

Interpretation Introduction

Interpretation:

The protons, electron and neutrons should be given for the set of compounds.

Concept introduction:

Atom:

Every atom is composed of a nucleus and one or more electrons bound to the nucleus. The nucleus is made of one or more protons and typically a similar number of neutrons.

Isotope:

Isotopes are variants of a particular chemical element which differ in neutron number whereas protons number is same. Isotopes are same atomic number but different in the mass number.

The element symbol, atomic number and mass number can be written as follows,

ZAX

A is Mass number (The total number of protons and neutrons in an atom) and it is written in the superscript.

Z is atomic number of the element and it is written in subscript.

X is the symbol of the element

Look up the valence electron configuration, covalent atomic radius, effective nuclear charge, first ionization energy and Pauling electronegativity in Chapter 8 (tables are attached). Examine the above data and answer the following questions. a) Explain why some of the elements like TI and Pb on the lower left of the p block are metallic. b) Explain why some of the elements like C, Si in the center of the p block form covalent bonds. Explain why these bonds formed by the network of these elements (as studied in Chapter 25) tend to be unreactive. c) Explain why the noble Group 8A elements are highly unreactive gases. d) Explain why some elements like F, CI, Br etc, on the upper right of the p block are highly reactive nonmetals.
