The mass number is the sum of the number of protons and neutrons, in this instance 16, more specifically O-16, since 8 protons is characteristic of oxygen.
8 protons and 9 neutrons (total is the atomic mass number 17). In a neutral atom, 8 electrons. Oxygen-17 is the rarest of the three stable natural isotopes. Most oxygen is oxygen-16 with 8 neutrons.
Oxygen has 8 electrons and protons. The number of neutrons is different for each isotope: Number of neutrons = Atomic mass of the isotope - Number of protons
An isotope of oxygen with atomic number 8 could have various numbers of neutrons, leading to different mass numbers. Isotopes such as oxygen-16 (8 protons and 8 neutrons), oxygen-17 (8 protons and 9 neutrons), and oxygen-18 (8 protons and 10 neutrons) are examples of isotopes of oxygen that exist.
The atomic number of element X is determined by the number of protons, which is 7. For the second isotope, which has 10 neutrons, the mass number is the sum of protons and neutrons, calculated as 7 protons + 10 neutrons = 17. Therefore, the second isotope has an atomic number of 7 and a mass number of 17.
The atomic mass of the isotope 15N is 15,000 108 898 2(7).
Oxygen has 8 protons . The number of neutrons depends on the isotope. Oxygen-15 isotope has 7 neutrons and oxygen-16 isotope has 8 neutrons. (Note: Mass number = Number of protons + number of neutrons)
8 protons and 9 neutrons (total is the atomic mass number 17). In a neutral atom, 8 electrons. Oxygen-17 is the rarest of the three stable natural isotopes. Most oxygen is oxygen-16 with 8 neutrons.
oxygen has 8 protons as its atomic number is 8. The number of neutrons depends on the isotope. O-15 isotope will have 7 neutrons, O-16 isotope will have 8 neutrons. (Note: Mass number = Number of protons + number of neutrons)
An isotope of Nitrogen shows 7 protons & 8 neutrons.
Oxygen has 8 electrons and protons. The number of neutrons is different for each isotope: Number of neutrons = Atomic mass of the isotope - Number of protons
Oxygen has 8 protons as its atomic number is 8. It therefore has 8 electrons also for charge neutrality. The number of neutrons depends on the isotope. O-15 isotope will have 7 neutrons, O-16 isotope will have 8 neutrons. (Note: Mass number = Number of protons + number of neutrons)
Oxygen has 8 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in an oxygen isotope = Mass number - 8
An isotope of oxygen with atomic number 8 could have various numbers of neutrons, leading to different mass numbers. Isotopes such as oxygen-16 (8 protons and 8 neutrons), oxygen-17 (8 protons and 9 neutrons), and oxygen-18 (8 protons and 10 neutrons) are examples of isotopes of oxygen that exist.
The atomic mass of the isotope 15N is 15,000 108 898 2(7).
14.
The atomic mass of an element is determined by the sum of the protons and neutrons in its nucleus. Beryllium has 4 protons and typically 5 neutrons, resulting in a total of 9 nucleons (protons + neutrons). This is why its atomic mass is 9 instead of 8.
The atomic mass of an atom with 10 Electrons and 11 Protons would be 11, assuming that there are no Neutrons present in the nucleus. If there are Neutrons present, they would add 1 for 1 to the mass.
