which of these properties is the best one to use for identification of an element?\no the number of neutrons in the atomic nucleus\no the number of protons in the atomic nucleus\no the number of isotopes that are formed by the element\no the number of charges on ions of the element
Answer
Brief Explanations:
The number of protons in the atomic nucleus, also known as the atomic number, is unique to each element. Isotopes of an element have different numbers of neutrons, and the number of charges on ions can vary. So the atomic - number (number of protons) is the best for element identification.
Answer:
the number of protons in the atomic nucleus
