The atomic number is 8 (the number of protons, which for oxygen is equal to the number of electrons) and the mass number is 17 (the combined number of protons and neutrons).

Is the atomic number of an atom equal to the number of protons or neutrons or electrons in the nucleus?
No, atomic number equals the number of protons.The number of neutrons is NOT specific to an element, and various atoms of the same element can have different numbers of neutrons - these are called isotopes.
What is the number neutrons and protons in californium?
Number of neutrons = Atomic mass of an isotope - atomic number of the element The atomic number of californium is 98. Number of neutrons = Atomic mass of an isotope - atomic number of the element The atomic number of californium is 98.
The mass number of an element is the number of?
Mass number is the atomic mass of a particular isotope (apex chem 5.3)
What is hydrogen's number of neutrons equals mass number - atomic number equals?
A hydrogen atom has one proton, one electron and '''zero''' neutrons. Rephrased, the question is: Hydrogen's number of neutrons equals mass number - atomic number.
Carbon has an atomic number of 6 how many protons and neutrons are in a nucleus of carbon 13?
12 - 6 = 6 neutrons; the number of neutrons in an isotope is always the mass number minus the atomic number.
How is the number of neutrons in an atom worked out?
they work because in every atom there is a neutron, electron and proton. the electron will tell you what the atomic number is and the neutrons and protons will tell you what element it is.
Does sodium have ten neutrons?
Actually, the element Sodium has eleven (11) electrons. You can tell by its Atomic number. (The number at the top left side of the element's box.)The Atomic number is both the element's proton and electron number.
Is there an element that has the same atomic number and atomic mass?
No, there is no naturally occurring element with the same atomic number and atomic mass. The atomic mass of an element is the weighted average of the masses of its isotopes, which have different numbers of neutrons. The atomic number of an element is the number of protons in its nucleus, which determines its identity. Therefore, the atomic number and atomic mass are different for each element.
What is the formula for the atomic number?
atomic number = number of proton in an element number of proton = number of electron mass number = number of proton + number of neutron therefore... atomic number = mass number - number of neutrons
How many neutrons dose hassium have?
Number of neutrons = Atomic mass of an isotope - Atomic number of the element The atomic number of hassium is 108; each isotope of an element has a different number of neutrons and a different atomic mass.
What equation is used to calculate neutrons for an element?
Number of neutrons = Atomic mass - Atomic number
Is the electron cloud of an atom the isotope?
No.The cloud of electrons surround the atomic nucleus and, for each individual element, there are a different number of electrons in the cloud. This number of electrons is matched by the samenumber of protons in the atomic nucleus.However, the atomic nucleus also contains neutrons, and there is a variable number of neutrons in the nucleus. It is this variation in the number of neutrons that makes the isotopes of an element.
How do you calculate neutrons for elements in the periodic table?
them mass number of an element is the total amount of nuetrons and protons in the element , and the atomic number is the amount of protons ( and electrons) in the element simply subtract the atomic number from the mass number and you'll have the number of neutrons in the element hope this helped x
What is the atomic number number of neutrons and the number of electrons of hydrogen?
Normal Hydrogen has an atomic number of 1, no neutrons and 1 electron.
How do scientists determine the number of neutrons and isotopes in an atom?
Atomic mass minus atomic number. This is rather simplified but the atomic mass of an element is the total of all the protons, neutrons, and electrons in an atom. Each proton and neutron has an atomic mass of approximately 1 AMU (atomic mass units) while an electron has an atomic mass of about 0.0005 AMU. So, you don't need to worry about the electrons. The atomic number of an element is simply the number of protons in the atom. So, atomic mass (number of protons and neutrons) minus atomic number (number of protons) equals number of neutrons in an atom.
How do you calculate the number of neutrons an atom of a specific element has?
First, find its atomic mass on the periodic table and subtract the number of protons (element number) from it and there you go
What is the number of neutrons for a specific element equal to?
The average number of neutrons that a specific element has is equivilent to the element's atomic mass minus the that elements atomic number. For example Helium has 2 neutrons because its atomic mass (4) minus the atomic number (2) is 2.
