63 State, in terms of the number of subatomic particles, one similarity and one difference between the atoms of these isotopes of sulfur. [1]
HIGHLIGHT TO SEE THE ANSWER
Similarity: All atoms of these isotopes have the same number of protons. Difference: An S-32 atom has 16 neutrons, an S-33 atom has 17 neutrons, an S-34 atom has 18 neutrons, and an S-36 atom has 20 neutrons. Similarity: Every sulfur atom has 16 protons. Difference: The number of neutrons in an atom of one isotope is different than the number of neutrons in an atom of a different isotope. MY Answer= Sim. # protons Differ. # neutrons (It is the definition of an isomer.) |
