How to calculate neutron?
Atomic mass - Atomic number
What is the formula to get a number atomic neutron?
No. of neutrons=Atomic mass - Atomic number
A gas with 8 neutron and 8 protons?
That would be a gas with the Atomic 8 and mass number of 16 - Oxygen
How do you calculate the number of neutron in the nucleus of an atom?
You calculate the number of neutron in the nucleus of an atom by : atomic mass - atomic number = neutron number. :) hope this helps
What is atomic mass A and neutron number N for given atom?
Atomic mass is the number of protons and neutrons that make up an atom. The neutron number is only the number of neutrons present in the atom. This can be found by subtracting the number of protons from the atomic mass.
What is the atomic number and atomic mass for oxygen?
Oxygen is a non meta element. Atomic mass of it is 16 Atomic number of it is 8.
What is the mass of oxygen 16?
If you really meant to ask "What is the mass defect of oxygen-16," this is how you do it. mass defect = # of protons x mass of one proton + # of neutrons x mass of one neutron - mass of the nucleus The atomic number of oxygen-16 is 8, so there are 8 protons. The mass of one proton is approximately 1.0073 amu. The Atomic Mass of oxygen-16 is 16, so there are 8 neutrons in oxygen-16. (Atomic mass of 16 minus atomic number of 8 = # of neutrons in oxygen-16.) The mass of one neutron is approximately 1.0087 amu. The mass of the nucleus of oxygen is 16. Now substitute the values into the "mass defect" equation: mass defect = 8x1.0073+8x1.0087-16=approximately 0.128 amu.
What is an electron's atomic mass number?
The electron has no atomic mass number. The mass of an electron is roughly 1/1800 of the mass of a proton or neutron.
How do you calculate the number of proton neutron and electron using atomic no and mass no?
atomic # = protons atomic mass - atomic number = neutrons atomic # - charge = electrons
What element has the neutron number of 30.69?
This is the weighted average neutron number for the naturally occurring isotopes of nickel, which has the atomic number 28 and the gram-atomic mass of 58.69. In an individual isotope, the neutron number is always the isotopic atomic mass number minus the atomic number, and the same principle applies to the weighted average neutron number for the naturally occurring isotopes of an element.
How many neutron are in oxygen?
There are 8 neutrons in oxygen. You can determine the number of neutrons in any element by subtracting the atomic number (which is 8 for oxygen) from the atomic mass, rounded to the nearest whole number (which is 16 for oxygen). This is because the mass of any element comes mainly from the protons and the neutrons - the mass of the electrons is too tiny to be a significant contribution. The atomic number corresponds to the number of protons in an element, so when you subtract it from the element's total mass, you are left with the number of neutrons.
How do you determine the number of neutron?
Protons = Atomic Number Electrons = Atomic Number Neutrons = Atomic Mass - Atomic Number *A note on Atomic Mass* Atomic Mass is the sum of the number of protons and neutrons in an atom. Every time you remove or add a Proton/Electron or a Neutron, you change the mass by one. *A note on Protons and Electrons* The number of Protons and Electrons in an atom is always the same. Whenever you talk about adding/removing a proton or an electron, you are by default adding/removing one of the other as well.
