The element with atomic number eight is oxygen, and anyatom of oxygen is an isotope. Let's see how that works.
The word isotope speaks to the number of neutrons in a given atom of a given element. When we speak of oxygen, we might consider any of its isotopes, but all atoms of this element have eight protons in their nucleus. They're all oxygen, and all have atomic number eight. Oxygen has three stable isotopes, and they are O-16, O-17 and O-18. All atoms of these isotopes have eight protons in them, but they have eight, nine and ten neutrons in their nuclei, respectively.
The element oxygen has eight protons, so an oxygen atom with an atomic mass of 15.9994 will have approximately eight neutrons. This is calculated by subtracting the atomic number (number of protons) from the atomic mass.
Oxygen is a gas element. atomic number of it is 8.
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. Therefore, atomic mass of oxygen is 15.
The atomic mass of the element with eight protons and nine neutrons is 17 atomic mass units. This is calculated by adding the number of protons and neutrons together, as electrons contribute negligible mass to the overall atomic mass.
The charged particles would be protons (+) and would have a mass of 7 ( which would also tell you its atomic number, making this element Nitrogen). If the uncharged particles are eight in number and like protons have a value of one, 7 + 8 = 15 for atomic mass. Since the actual atomic mass of N is 14.007, the difference in mass tells us that we are talking about an isotope of N.
Atomic number 8 belongs to Oxygen!
The element oxygen has eight protons, so an oxygen atom with an atomic mass of 15.9994 will have approximately eight neutrons. This is calculated by subtracting the atomic number (number of protons) from the atomic mass.
Oxygen is a gas element. atomic number of it is 8.
The atomic mass is the number of protons, plus the number of neutrons. In this case, 8 + 6 = 14.Furthermore, the six protons (atomic number) tells me that this is carbon; the six electrons tell me that this is a carbon atom, rather than a carbon ion (an ion is when the number of electrons does not equal the number of protons, making the atom electrically non-neutral). The eight neutrons tell me that this is an isotope (in other words, a version) of carbon called carbon-14, which happens to be mildly radioactive; and therefore useful to archaeologists in dating human artifacts.
The element with 8 protons, 9 neutrons, and 8 electrons is oxygen-17. Oxygen normally has 8 protons and 8 neutrons, but oxygen-17 is a rare isotope with an extra neutron. This gives it a total of 8 protons, 9 neutrons, and 8 electrons.
The element is carbon and the isotope is 6C14
The atomic number of nitrogen is 7. When it is a radioactive isotope you add the number of neutrons to the atomic number (equaling 15). You then write 15 over 7 next to a capital 'N' representing Nitrogen.
Darmstadtium is an artificial element; no stable isotopes exist. From Wikipedia: "Eight different isotopes of darmstadtium have been reported with atomic masses 267, 269-271, 273, 277, 279, and 281, ..." The numbers are protons + neutrons. Subtract 110 (the atomic number for this element) to subtract the protons, and get the number of neutrons for the different isotopes. In other words, between 157 and 171, depending on the isotope.
The atomic weight of an element is the weighted average of the masses of its isotopes. For an element with 8 protons and 8 neutrons (oxygen-16 isotope), the atomic weight would be close to 16 g/mol due to the equal number of protons and neutrons.
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. Therefore, atomic mass of oxygen is 15.
The atomic number is equal to the number of protons in the nucleus of an atom of that element. For example, oxygen has eight protons in its nucleus, helium has two, and hydrogen has one.
Oxygen. The Elements Atomic Number tells you the number of protons and it's amu is generally the weight of all of the averaged isotopes so since it is nearly 16 (not all O's have 8 neutrons) it is Oxygen.
