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.
What is the mass number of an oxygen atom with 7 neutrons?
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.
Simply add the protons and neutrons, resulting in 15 as the mass number
The mass number (aka nucleon number) is 17.
Oxygen-17 occurs naturally as 0.04% of oxygen.
The atomic number of oxygen is 8. What is the mass number of a oxygen atom with 7 neutrons?
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 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.
they determine the atomic mass of the atom
There are no 'nucleons' in an Oxygen atom. You mean 'neutrons'. As all the mass of an atom is in its nucleus (made up of 'protons' and 'neutrons') and as the Atomic Number is the count of how many 'protons' there are, if you subtract the Atomic Number form the Atomic Mass, you get the number of 'nutrons'. 17-8=9.
8. When an atom becomes an ion, it gains or loses electrons. The number of protons and neutrons doesn't change. If the number of neutrons changes then the atom has changed into a different isotope.
you take the atomic mass of an atom say, 16 for oxygen, and subtract the atomic number, 8 for oxygen. 16-8= 8. so there are eight neutrons in the typical oxygen atom.
The number of neutrons in an atom can affect the atomic mass of an atom.
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 atomic number refers to the number of protons in an element. The mass number can be used to indicate the number of neutrons because both protons and neutrons have a mass of about 1. An oxygen atom has 8 protons and 8 neutrons.
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.
they determine the atomic mass of the atom
Atomic number is number of protons in an atom while atomic mass is the sum of protons and neutrons in an atom when you subtract you will get the number of neutrons in an atom.
The mass number =18
There are no 'nucleons' in an Oxygen atom. You mean 'neutrons'. As all the mass of an atom is in its nucleus (made up of 'protons' and 'neutrons') and as the Atomic Number is the count of how many 'protons' there are, if you subtract the Atomic Number form the Atomic Mass, you get the number of 'nutrons'. 17-8=9.
You subtract the atomic number from the atomic weight. For example, if you have a helium atom and its atomic weight is 4 and you subtract its atomic number (2) the number of neutrons in the helium atom is 2.
8. When an atom becomes an ion, it gains or loses electrons. The number of protons and neutrons doesn't change. If the number of neutrons changes then the atom has changed into a different isotope.
There are always 8 protons in Oxygen. This is represented by the atomic number of oxygen. As for electrons , they are often represented by the atomic number in the neutral form, 8, but if the oxygen atom is a ion it would have 10 electrons. For neutrons the average atomic mass is 16.01, neutrons are found by subtracting the number of protons from the atomic mass, so 16.01-8=8.01, there 8.01 average neutrons in oxygen, but in isotopes oxygen can have differnet amounts of neutrons, the mainest is 8 neutrons.
