What is the mass number for oxygen 18?
The mass number for oxygen-18 is 18. This is calculated by adding together the number of protons and neutrons in the nucleus of an oxygen-18 atom. It is a stable isotope of oxygen with 8 protons and 10 neutrons.
What is the atomic number for the oxygen atom?
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.
What are the atomic number and mass number if the number of electron in an element oxygen is 8 and the number of neutrons is 9?
The atomic number of an element is the number of protons in its nucleus, which is also equal to the number of electrons in a neutral atom. Given that the number of electrons in oxygen is 8, the atomic number is 8. The mass number is the sum of protons and neutrons in the nucleus, so for oxygen with 8 protons and 9 neutrons, the mass number is 8 + 9 = 17.
What is the mass number of 15.9994?
The mass number of an element is the sum of the number of protons and neutrons in the nucleus of an atom. For an atom with a mass number of 15.9994, it indicates the average atomic mass of an oxygen atom.
Is the mass of a hydrogen atom different from the mass of an oxygen atom?
Yes, the mass of a hydrogen atom is different from the mass of an oxygen atom. A hydrogen atom has a much smaller mass compared to an oxygen atom because it only consists of one proton and, in most cases, one electron, whereas an oxygen atom has more protons, neutrons, and electrons in its structure.
What is the mass number of oxygen-8?
Oxygen is a non metallic element. Mass number of it is 16.
What is the mass number of oxygen 8?
No,the mass number of oxygen is 16 because it's atomic number is 8
What is mass number of oxgen?
The mass number of oxygen is 16. This number represents the total number of protons and neutrons in the nucleus of an oxygen atom.
What is the mass number of most atoms of oxygen?
The most common isotope of oxygen has a mass number of 16. This isotope, known as oxygen-16, accounts for over 99% of naturally occurring oxygen atoms.
What is the mass number for O?
The mass number for oxygen (O) is 16, as it is the sum of the number of protons and neutrons in its nucleus.
The number of moles of oxygen in the reaction vessel is?
To calculate the number of moles of oxygen in the reaction vessel, you need to know the amount of oxygen in grams and its molar mass. Then divide the mass of oxygen by its molar mass to obtain the number of moles. The formula to calculate the number of moles is: moles = mass / molar mass.
What is the mass number for oxygen 18?
The mass number for oxygen-18 is 18. This is calculated by adding together the number of protons and neutrons in the nucleus of an oxygen-18 atom. It is a stable isotope of oxygen with 8 protons and 10 neutrons.
What the mass number oxygen?
Oxygen is a non metal element. Atomic mass of it is 16.
What is mass number of oxygen?
Oxygen is a non metal element. Atomic mass of it is 16.
Why is 16 oxygen mass number?
Oxygen typically has a mass number of 16 because an oxygen atom has 8 protons and 8 neutrons in its nucleus. The mass number is the sum of the protons and neutrons in an atom's nucleus.
He atomic number of oxygen is 8 What is the mass number of an oxygen atom with 7 neutrons?
The atomic mass of oxygen (8 protons + 7 neutrons) is 15.For finding the atomic mass of any element, we have to get sum of number of protons & number of neutrons. Atomic Mass (A) : p+n.p = no. of protons.n = no. of neutrons.
