Oxygen-16 has 8 protons (because it's oxygen) and 8 neutrons (because it's the same number and 16-8=8.) That's by far the most common isotope of oxygen, since oxygen's Atomic Mass on the Periodic Table is 15.999.
What else can I help you with?
What isotope has 20 protons and 22 neutrons?
The number on the periodic table is the number of protons it contains. The isotope number is the sum of the protons and neutrons.Therefore, the isotope with 20 protons and 22 neutrons is Calcium-42.
What contains promethium?
The atom of promethium contain 61 protons and electrons.For each isotope the number of neutrons is different. Number of neutrons = Mass number of an isotope - 61
A common isotope of carbon has a mass number of 13 The total number of protons and neutrons in the nucleus is?
13. The mass number is always the total number of protons and neutrons.
What is the isotope for mass number 54 and contains 24 protons?
Any isotope with 24 protons is chromium; therefore, the requested isotope is 54Cr.
What are the number of protons neutrons and electrons in boron?
Boron has 5 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a boron isotope = Mass number - 5
What is the mass number of an oxygen isotope that has nine neutrons?
The mass number of an isotope is the sum of its protons and neutrons. For oxygen, which has 8 protons, an isotope with nine neutrons would have a mass number of 8 (protons) + 9 (neutrons) = 17. Therefore, the mass number of this oxygen isotope is 17. This isotope is known as oxygen-17.
How many protons and neutrons are in promethium?
Promethium has 61 protons and electrons.For each isotope the number of neutrons is different. Number of neutrons = Mass number of an isotope - 61
How does the atomic number relate to the number of protons in an atom?
Atomic Mass (of an isotope) - number of protons (of an isotope) = number of neutrons (of an isotope)
If an isotope of silicon has 15 neutrons what is its mass number?
The mass number of an isotope is the sum of its protons and neutrons. Since silicon has 14 protons, the isotope with 15 neutrons would have a mass number of 14 (protons) + 15 (neutrons) = 29.
How may protons neutrons and electrons In lawrencium?
Number of neutrons = Atomic mass of an isotope - Atomic number of the element; the atomic number of Lr is 103. Lawrencium has many isotopes and each isotope has a different number of neutrons.
Is 112Cd an isotope?
Yes 112Cd is an isotope of cadmium, called cadmium-112, which contains 48 protons and 64 neutrons. Cadmium-112 has a mass number of 112, which is the sum of the protons and neutrons in the atomic nuclei of the atoms of this isotope.
What is the mass number of an oxygen isotope that has 9 neutrons?
The mass number of an isotope is the sum of its protons and neutrons. Oxygen has an atomic number of 8, meaning it has 8 protons. If the isotope has 9 neutrons, the mass number would be 8 protons + 9 neutrons = 17. Therefore, the mass number of this oxygen isotope is 17.
