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?
they are different isotopes of oxygen, oxygen-17 has one more neutron than oxygen-16 making it slightly heavier. Oxygen-17 will react slightly slower than oxygen-16 since it has more mass.
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 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).
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.
What is the mass of oxygen-18?
As the name would suggest, the mass of Oxygen-18 is 18.
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.
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.
Is 18 O an isotope?
Number of Neutrons = Atomic mass minus Atomic Number. Neutrons = 18[Atomic Mass] - 8[Atomic Number] Neutrons = 10
What is the atomic number for an oxygen atom that has 10 neutrons in it's nucleus?
The mass number =18
What is an oxygen atom with 10 neutrons?
write the anatomic symbol for isotopes with the an oygen atom with 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.
Sn isotope of oxygen has an atomic number of 8 and an atomic weight of 18. how many neutrons does it have?
The atomic number of an isotope is the number of protons it contains, whereas the mass number is the total mass of the nucleus, which is the combined number of protons and neutrons in the nucleus. To find the number of neutrons, you must therefore subtract the atomic number of the isotope from the mass number of the isotope.In the above example, the atomic number is 8 and the mass number is 18. This isotope is known as O18. The number of neutrons in the isotope is: Mass number - Atomic number = Number of neutrons18 - 8 = 10
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?
16
What is the symbol for oxygen -17?
I think it is H217O in its water form and Oxygen-17,17O in its atomic form.
What is the mass number of oxygen-8?
Oxygen is a non metallic element. Mass number of it is 16.
