Answer is B) - neutrons.
Both protons and neutrons contribute to the mass of an atom. But ₈¹⁷O atom has atomic number as 8. Hence, number of protons is 8. Atomic mass of the given atom is 17.
Atomic mass = number of protons + number of neutrons
Hence, number of neutrons in the given atom is 17 - 8 = 9.
So, the number of neutrons is greater than the number of protons. Hence the greatest composition of ₈¹⁷O atom is neutrons by mass.
Answer:
chewing sugar-free gum can help stimulate the production of damage
Answer:
See the explanation below, please.
Explanation:
Isotopes correspond to atoms with the same atomic number (Z) but different mass numbers (A), that is, they differ in the number of neutrons. Ex Carbon 14 and Carbon 12, Hydrogen and Deuterium.
Isotopes can be determined using the mass spectrometry technique, measuring the relative abundance of each ion (gives us the m / z, ratio between mass and charge).
