The atomic number of oxygen is 8, which means that there are 8 protons in the nucleus of an oxygen atom. Mass number = protons + neutrons, therefore neutrons = mass number - protons = 16 - 8 = 8 neutrons.
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.
There are 8 neutrons in an oxygen-16 atom. Oxygen has an atomic number of 8 and with an atomic mass of 16, it is simple to calculate the number of neutrons by subtracting the atomic number (8) from the atomic mass (16). The 16 - 8 = 8.
Oxygen is a non metal element. Atomic mass of it is 16.
Oxygen has 8 protons . The number of neutrons depends on the isotope. Oxygen-15 isotope has 7 neutrons and oxygen-16 isotope has 8 neutrons. (Note: Mass number = Number of protons + number of neutrons)
Oxygen is a non metal element. Atomic mass number of it is 16.
Oxygen is a non metallic element. Mass number of it is 16.
No,the mass number of oxygen is 16 because it's atomic number is 8
Oxygen is a non metal element. Atomic mass of it is 16.
Oxygen is a non metal element. Atomic mass of it is 16.
Oxygen is a non metal element. Mass number of it is 16.
The atomic number of oxygen is 8, which means that there are 8 protons in the nucleus of an oxygen atom. Mass number = protons + neutrons, therefore neutrons = mass number - protons = 16 - 8 = 8 neutrons.
The mass number is the sum of neutrons and protons in the atomic nucleus and is different for each isotope of any element.For example the isotope oxygen-16 has the mass number 16.The mass number is not the atomic mass !!
The atomic weight (not mass) of oxygen is [15,99903; 15,99977] or in an abridged form 15,999. The term atomic mass is used only for isotopes. The mass number is the sum of neutrons and protons in an atomic nucleus.
As the name would suggest, the mass of Oxygen-18 is 18.
The atomic mass number of oxygen is 16.0. --------- The mass number is the sum of neutrons and protons in the atomic nucleus and is different for each isotope of any element. For example the isotope oxygen-16 has the mass number 16. After IUPAC Tables from 2009 the atomic weight of oxygen is [15,99903; 15,99977]. The conventional (abridged) atomic weight is 15.999 amu.
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.
