CHEM 120 Week 1 DQ 2 – Atoms and Atomic StructureThere are a number of elements (minerals) that are important to human nutrition. These include
sodium, potassium, calcium, chloride, magnesium, iron, copper, manganese, iodine,
molybdenum, and selenium. There are many additional elements that are useful in industry.
Using the periodic table of elements, pick one of these elements and determine the number of
protons, neutrons, and electrons found in this atom. Be sure to check that you are not doing an
element that another person has already posted.
Check out the interactive periodic table in the Week 1 Lecture for more information on how to
calculate the number of protons, neutrons, and electrons. It is recommended to print a copy of the
table from the interactive periodic table.
Next write your own isotope question by giving the number of protons and neutrons in an
element without giving the name or chemical symbol of the element. Each of your classmates
will do the same, and then you can solve 12 of your peers’ questions.
Make sure to post at least three high quality posts. Your instructor will open new topics of
discussion throughout the week.
