CHEM-120 Week # 1 DQ 2 – Atoms and Atomic Structure

There 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.
Oxygen is a chemical element with symbol O and atomic number 8. It is a member of the

chalcogen group on the periodic table, a highly reactive nonmetal, and an oxidizing agent that

readily forms oxides with most elements as well as with other compounds.

Symbol: O

Atomic number: 8

Atomic mass: 15.999 which also can be around up to 16

Number of Protons = the number of Electrons which is 8

In order to know the number of neutrons

Subtract number of protons from the atomic mass

16 – 8 = 8

Protons = 8

Electrons = 8

Neutrons = 8

Atomic Mass = approximately 16

Question for Class:

What Isotope is a radioactive isotope of with an atomic nucleus containing 6 protons and 8

neutrons.
