Atoms of oxygen-16, oxygen-17 and oxygen-18 are isotopes. Compare and contrast these three isotopes.

There are three isotopes of the element oxygen (O): Oxygen 16, 17, and 18. Each isotope of oxygen contains 8 protons, but differs in the number of neutrons. ... Therefore, oxygen 16 has 8 protons and 8 neutrons, oxygen 17 has 8 protons and 9 neutrons, and oxygen 18 has 8 protons and 10 neutrons.

Chemical elements are found in different versions, called isotopes. Isotopes are elements that contain the same amount of protons, but differ in the number of neutrons in their nuclei. For example, there are three isotopes of the element oxygen (O): Oxygen 16, 17, and 18. Each isotope of oxygen contains 8 protons, but differs in the number of neutrons. An isotope number is a shorthand representation of its mass. Because protons and neutrons are roughly equal in mass, an isotope’s number is equal to the sum of its protons and neutrons. Therefore, oxygen 16 has 8 protons and 8 neutrons, oxygen 17 has 8 protons and 9 neutrons, and oxygen 18 has 8 protons and 10 neutrons.

There are two main types of isotopes that geoscientists use to interpret the ancient Earth: stable and unstable isotopes.

Ibelieve your answer is true 

If a hydrogen atom is neutral, it must also have  one electron. an oxygen atom (o) has an atomic number of eight (8). this means a neutral oxygen atom has eight protons and eight electrons. the element actium (ac) has an atomic number of 89, so it has 89 protons and 89 electrons in a neutral atom
