CHEM 103 MIDTERM 2 QUESTIONS AND
ANSWERS WITH COMPLETE
SOLUTIONS 100% CORRECT RATED A+
The $s$-Block (Blue)
The $s$-block consists of the first two groups of the periodic table: the alkali
metals (Group 1) and the alkaline earth metals (Group 2), plus Helium.
Electron Capacity: An $s$ subshell contains a single orbital and can hold a
maximum of 2 electrons.
Characteristic: These elements are generally highly reactive metals (except
for Hydrogen and Helium) whose valence electrons are in an $s$ orbital.
The $p$-Block (Red)
The $p$-block encompasses groups 13 through 18 (excluding Helium). This
diverse block contains all of the nonmetals, metalloids, and post-transition
metals.
Electron Capacity: A $p$ subshell contains three orbitals and can hold a
maximum of 6 electrons.
Characteristic: This block includes the halogens and noble gases,
characterized by filling their $p$ valence shells.
The $d$-Block (Green)
The $d$-block contains the transition metals, located in the central part of the
periodic table (Groups 3 through 12).
Electron Capacity: A $d$ subshell contains five orbitals and can hold a
maximum of 10 electrons.
Characteristic: These elements are all metals and are known for having
variable oxidation states and forming colored compounds.
The $f$-Block (Yellow)
