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 number of an atom is determined by the number of protons it contains. Since the atom in question has 8 protons, its atomic number is 8. This corresponds to the element oxygen on the periodic table. The presence of 8 neutrons and 8 electrons indicates that this specific atom is a neutral isotope of oxygen, specifically oxygen-16.
The number of neutrons in the atoms of a specific element can vary, leading to the formation of isotopes. While all atoms of a given element have the same number of protons (defining the element), the neutron count can differ, affecting the atomic mass and stability of the isotopes. For example, carbon typically has six neutrons, but carbon-14, an isotope of carbon, has eight neutrons. These variations can influence the element's properties and behavior in chemical reactions.
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 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 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.
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.
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.
The element is carbon and the isotope is 6C14
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.
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.
The most common isotope of calcium (40Ca) has 20 neutrons. You can find this out by subtracting the number of protons (atomic number, 20), from the total AMU's of 40. About 96% of calcium on Earth is calcium-40. Calcium also has eight other isotopes, 41Ca through 48Ca, five of which are radioactive. The second-most prevalent stable isotope is 44Ca which is about 2% of all calcium.
