8 pariticals
Eight protons in the nucleus of each atom.
Learn that the atomic number means the number of protons. The mass number is the number of protons and the number of neutrons. So if we take the number of protons from the mass number then we get the number of neutrons that are present (mass umber - atomic number = number of neutrons). in this case 15 - 8 = 7. Since you dont mention there is any charge on the atom ill assume that its charge is neutral. For an atoms charge to be neutral then the positive charges from protons must equal the negative charges from electrons and vica versa. So for this to be the case with 8 protons then we must have 8 electrons.
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
Oxygen is a gas. atomic number of it is 8.
Oxygen has an atomic number of 8. This also means that it has 8 protons in its nucleus.
The number of neutrons in an atom can be calculated by subtracting the atomic number from the atomic mass. In this case, an atomic mass of 16 and atomic number of 8 for oxygen means there are 8 neutrons (16 - 8 = 8).
It would be 8, and it is the element oxygen. The atomic number is simply the number of protons in the element.
There is no element with an atomic number of 12 and an atomic mass of 8. Atomic number corresponds to the number of protons in an atom, while atomic mass is the sum of protons and neutrons. The atomic number of an element cannot be smaller than its atomic mass.
An atom with atomic number 8 corresponds to oxygen. Oxygen has 8 electrons because the number of electrons in an atom is equal to its atomic number.
The atomic number of an element refers to the number of protons in its nucleus. For oxygen (O), the atomic number is 8. So in O2 (oxygen molecule), each oxygen atom contributes its atomic number (8) to the total atomic number for the molecule.
Atomic number 8 and mass number sixteen is Oxygen
No, the atomic number relates to the number of protons and electrons. say if the atomic number is 8 and the atomic mass is 17. by looking at the atomic number you can tell there are 8 protons and 8 electrons. but now you want to find the number of neutrons. you see that the atomic mass is 17. so you subtract the atomic number from the atomic mass. which is 17-8= 9. so there are 8protons, 8electrons, and 9 neutrons. hope this helps you.
