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.

What element has an atomic number of eight?
Oxygen is a gas element. atomic number of it is 8.
Oxygen has eight protons eight neutrons and eight electrons what is the atomic mass?
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.
What element has 8 protons 8 electrons and 7 neutrons?
Oxygen because its atomic number is eight
The atomic mass of an atom with six electrons eight neutrons and six protons is?
You need to know the atomic number to find the element, and the atomic number equals the # of protons and electrons, which is 6. It is Carbon.
If the number of charged and uncharged particles in the center of an atom are 7 and 8 respectively.What is the mass number of the atom?
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.
What element has eight as its atomic number?
Atomic number 8 belongs to Oxygen!
What element has 8 protons 9 neutrons and 8 electrons?
Giving a specific number of protons and neutrons specifies an isotope of an element. In this case, the isotope is the isotope of fluorine with an atomic mass of 19. Other isotopes of fluorine with different numbers of neutrons also exist, but are not nearly as common.
A radioactive isotope has eight neutrons Write the atomic number and mass number of this radioactive nitrogen as a chemical symbol with a subscript and superscript?
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.
What element has an atomic number of eight?
Oxygen is a gas element. atomic number of it is 8.
How many neutrons are there in calcium?
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.
Oxygen has eight protons eight neutrons and eight electrons what is the atomic mass?
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 oxygen 8 indicates that there are eight?
The atomic number organizes the elements and also tells you how many protons there are in an element. So, oxygen would have 8 protons.The atomic number of oxygen 8 indicates that there are eight protons.
How many neutrons does the element Ds have?
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.
What radioactive element has six electrons and eight neutrons?
The element is carbon and the isotope is 6C14
An atomic number is equal to?
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.
If an atom six protons eight electrons and six neutrons what element is it?
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.
What characteristics must a substance have in order to be classified as an element?
Each element has a specific number of protons in the nuclei of its atoms. This number is known as the atomic number for the element. For instance, the atomic number of hydrogen is one because it has a just one proton in its nucleus. The atomic number of oxygen is eight, again because it has eight protons in its nucleus.
