Chapter 2.1, Problem 1TYK
Summary Introduction
Introduction:
Periodic table is the arrangement of elements according to their atomic number, electron configuration. There is a periodic arrangement of chemical properties of the elements in the periodic table. Chemical element is a substance that cannot be decomposed into simpler substances by ordinary chemical processes. Inside an atom there is a nucleus and it contains protons and neutrons in it as subatomic particles. Nucleus is surrounded by a cloud of electrons. Atomic number of an element is always similar to the number of protons inside the nucleus.
Electron shells are the energy levels that have the ability to hold up the electrons. Electron shells consist with one or more electron subshells.

Element Z forms an ion Z 3+, which contains 31 protons. What is the identity of Z, and how many electrons does Z3+have?
Could you give the formula name and whether it is ionic or covalent? Please explain how to provide the correct formula name and why that is.
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.
