What is the mass number of oxygen 8?

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.

Oxygen is a non metal element. Mass number of it is 16.

The atomic mass of oxygen is 15.9994~16

Oxygen does. The atomic mass is protons + neutrons, and the atomic number is the number of protons. Oxygen has an atomic number of 16-8=8.

Atomic number 8 and mass number sixteen is Oxygen

If an isotope has an atomic number of 8 and a mass number of 16 - IT IS OXYGEN

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.

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.

The mass number (aka nucleon number) is 17. Oxygen-17 occurs naturally as 0.04% of oxygen.

Oxygen is a non meta element. Atomic mass of it is 16 Atomic number of it is 8.

Oxygen has 8 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in an oxygen isotope = Mass number - 8

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).

The atomic number of oxygen is 8. 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 only particles with significant mass in an atom are the protons and neutrons. Each has a mass of 1 amu (equals 1 mass number). The oxygen atom with 8 protons and 8 neutrons would have a mass number of 16. The mass of the electrons is insignificant, like the flies on the elephants back.

Yes. The most common isotope of oxygen is oxygen-16, and the atomic number of oxygen is 8. The number of neutrons is the isotope mass number minus the atomic number, and 16 - 8 = 8.

Oxygen has 8 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in an oxygen atom = Mass number - 8

Oxygen has 8 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in an oxygen isotope = Mass number - 8

There are 8 neutrons in oxygen. In order to get number of neutrons, you will subtract the number of protons which is 8 from the atomic mass weight of oxygen which is 16.

Atomic number is 8. Mass number is 16.9991315 u

The isotope oxygen-18 has the mass number of 18. The atomic number of oxygen is 8, so all of its atoms, regardless of isotope, have 8 protons. In a neutral oxygen atom the number of protons equals the number of electrons, so it has 8 electrons. The number of neutrons equals the mass number minus the atomic number, which for oxygen-18 is (18 - 8), so there are 10 neutrons.

To find the number of protons, you use the atomic number. The atomic number is always the same number of protons. To find the average number of neutrons, you use the atomic mass and take away the number of protons. For example Oxygen has an atomic number of 8 and an atomic mass of 16.01, so since it has an atomic number of 8, it always has 8 protons, and since oxygen has a mass… Read More

atomic weight of oxygen is 15.9997 atomic number of oxygen is 8 hope i helped:)

The difference between Oxygen - 15 and Oxygen - 16 is that of Isotope. Oxygen's atomic number is 8 as it contains 8 proton but the neutron number may vary in order to form an isotope, the oxygen found in the air is 98 percent oxygen 16, the rest is oxygen 15. Oxygen 16 = 8 protons, 8 neutrons, 8 electrons. 16 is the mass number which is equal to the (number of proton +… Read More

Oxygen has 8 protons and electrons. The number of neutrons is variable and specific for each isotope. Number of neutrons in an oxygen isotope = Mass number - 8

Oxygen has 8 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in an oxygen isotope = Mass number - 8

The number of neutrons is 8. You can find this number by subtracting the atomic number from the mass number, or 16 - 8 is equal to 8.

Oxygen has a mass number of 16.00 with atomic number 8 which means there are 8 electrons and 8 protons. The number of neutrons is always equal to the mass number- the atomic number. In this case it is 16 - 8= 8. Protons: 8 Neutrons: 8 (for isotope O16 the most common) Electrons: 8

Isotopes are different forms of the same element with the same number of protons but different number of neutrons. The atomic number of oxygen is 8. So both oxygen-16 and oxygen-17 have 8 protons (and 8 electrons). You get the number of neutrons by subtracting the mass number by the atomic number, so they would have 8 and 9 neutrons respectively.

The isotope 15O has 8 protons and 7 neutrons; the atomic mass is approx. 15 (more exactly 15,003 065 6), the atomic number is 8.

No. If I recall correctly, Hydrogen has mass 1 (1 proton) and Oxygen mass 16 (8 protons + 8 neutrons).

The atomic number refers to the number of protons in the element. And since the number of protons = number of electrons, the atomic number is also the number of electrons in the element. The mass number of an element refers to the number of neutrons and protons in the element. &since electrons are negligible in mass, the number of neutrons can be found out by subtracting the atomic number from the mass number. Take… Read More

Ordinary oxygen has 8 protons and 8 neutrons for a mass number of 16, so a couple of extra neutrons takes it up to 18.

oxygen: atomic symbol: O atomic #: 8 atomic mass: 15.999 protons: 8 (this is the same as atomic #) neutrons: 7 electrons: 8 (generally the same as protons)

All oxygen atoms have 8 protons, and the isotope with mass number 17 has 9 neutrons, since the mass number is the sum of the protons and neutrons.

7 neutrons + 8 protons = mass number of 15

oxygen has 8 neutrons. you get the answer by subtracting the atomic numner for oxygen which is also the number of protons, from the atomic mass. 16 - 8 = 8

number of neutrons = (rounded) atomic mass - atomic number = neutrons 16-8= 8 neutrons : )

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… Read More

Mass number = Number of protons + number of neutrons = 8 + 10 = 18

an oxygen atom has the atomic number of 8. meaning it has 8 protons, and 8 electrons. also, it has a mass number of 16. therefore, the number of neutrons must be 8 as well, as the protons and neutrons have a mass of 1 amu and the electrons have no charge. :)

the answer would be 8.

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)

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… Read More

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 atomic weight of oxygen (not atomic mass) is [15,99903; 15,99977] after the IUPAC Tables - 2009. The atomic number of oxygen is 8.

This element is oxygen (O).

8. with an atomic mass of 15.9994

15.999 and 8 respectively.

This certain isotope of oxygen would have a mass of about 18 because electrons weigh almost nothing.

Simply add the protons and neutrons, resulting in 15 as the mass number

The atomic number of Oxygen is 8 and hence it has 8 protons and 8 electrons. Oxygen has a mass number of 16. The number of neutrons is obtained my subtracting the number of protons from the mass number, i.e., 16-8 = 8. Therefore, Oxygen has 8 protons as well as 8 neutrons. Now, Fe (Iron) is an interesting element. It has many isotopes. So, the exact number of neutrons is an estimated value. However… Read More
