An oxide ion formed from an oxygen -18 atom contains exactly how many protons neutrons and electrons?
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.
What is the oxygen mass number?
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.
Is oxygen 17 and oxygen 18 the same isotopes of oxygen?
No, oxygen-17 and oxygen-18 are different isotopes of oxygen. They differ in the number of neutrons each atom contains. Oxygen-17 has 8 protons and 9 neutrons while oxygen-18 has 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.
Is this true that a normal atom of oxygen has a mass of 16 the isotope oxygen 18 and protons 18?
An atom of oxygen typically has 8 protons, 8 neutrons, and 8 electrons, giving it a mass number of 16. Oxygen-18, on the other hand, has 8 protons and 10 neutrons, totaling a mass number of 18.
A molecule of water is composed of two atoms of hydrogen and one atom of oxygen if the atomic mass number of hydrogen is 1 and the molecular mass of water is 18 the atomic mass of oxygen must be?
The molecular mass of water (H2O) is 18, which means the total mass of one oxygen atom and two hydrogen atoms is 18. Since the atomic mass number of hydrogen is 1, the atomic mass of oxygen can be calculated as 16 (18 - 2).
What is the mass number of the elementoxygen?
It depends on the isotope of oxygen. There are three isotopes of oxygen with mass numbers of 16, 17, and 18.
Is 18 O an isotope?
Yes, 18O is an isotope of oxygen. It has a different number of neutrons compared to the more common isotope of oxygen (16O), which affects its atomic mass.
What is the mass of oxygen-18?
As the name would suggest, the mass of Oxygen-18 is 18.
Does oxygen -16 and oxygen -18 have different mass numbers?
The numbers 16 and 18 is their nucleon number. Hence, they will have different masses since they have different number of neutrons.
An oxide ion formed from an oxygen -18 atom contains exactly how many protons neutrons and electrons?
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.
What you the mass number of H2o?
The mass number of water (H2O) is calculated by summing the atomic masses of its components. Hydrogen has an atomic mass of 1 and oxygen has an atomic mass of 16. Therefore, the mass number of water is 18.
What is the atomic number for an oxygen atom that has 10 neutrons in it's nucleus?
The mass number =18
What is the oxygen mass number?
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.
What is an oxygen atom with 10 neutrons?
An oxygen atom with 10 neutrons would have a mass number of 17 (8 protons + 10 neutrons) and isotope oxygen-17. This isotope is a rare form of oxygen and differs from the more common oxygen-16 isotope in having two extra neutrons.
What is the total number of neutrons in an atom of 0-18?
An atom of oxygen-18 has 10 neutrons. This is calculated by subtracting the atomic number (8) from the atomic mass (18).
