Ch 100: Fundamentals for Chemistry
Chapter 5: Worksheet (Naming Compounds)
Naming elements (part 1):
Using the periodic table (or table of elements) write the chemical formula for each
element and determine whether each element is a metal, metalloid, or non-metal.
a) hydrogen H2, non-metal
b) helium He, non-metal
c) calcium Ca, metal
d) gold Au, metal
e) chlorine Cl2, non-metal
f) silicon Si, metalloid
g) sodium Na, metal
h) sulfur S, non-metal
Naming elements (part 2):
Using a Table of Elements write the chemical name for each element and determine
whether each element is a metal, metalloid, or non-metal
a) Pb lead, metal
b) K potassium, metal
c) Ag silver, metal
d) Pt platinum, metal
e) Hg mercury, metal
f) As arsenic, metalloid
g) Ne neon, non-metal
h) Fe iron, metal
Identifying Ions using the Periodic Table:
Identify the type of ion (cation or anion) and charge (2+, 1-, etc.) that is formed by each
of the following elements:
a) H cation, H+ or anion, H-
b) Cl anion, Cl-
c) Ne does not form an ion
d) Ca cation, Ca2+
e) Al cation, Al3+
f) O anion, O2-
Naming the Ions:
Name the ion formed by the following elements (use the textbook if necessary):
a) Na sodium ion
b) I iodide ion
c) He does not form an ion
d) Mg magnesium ion
e) Al aluminum ion
f) Hg mercury(I) or mercury (II)
