Answer:
Sodium Hydroxide turns blue litmus red .
Answer: Some atoms of the same elements that have different atomic masses are called isotopes
Explanation:
so the atoms are the same element but different in mass. Since the isotopes have the same number of protons and electrons the isotopes have much the same chemical behavior. Since the isotopes have different numbers of neutrons the nuclear behavior differs.
Mass
Explanation:
Mass is different from the rest based on those two categories.
Physical properties are the properties of matter that are usually determined with our senses like taste, feel, color, odor e.t.c
Chemical properties are the properties that relates to a substance when changes are occurring to it.
