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.

How many neutrons and electrons does an oxygen atom have?

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)


How many protons and neutrons are in oxygen-17?

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.


How many protons neutrons does oxygen have?

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)


What isotope does this show 7 protons 8 neutrons?

An isotope of Nitrogen shows 7 protons & 8 neutrons.


How many numders of neutrons and electrons does oxygen have?

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


How many protons electrons and neutrons does oxygen have?

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)


How much subatomic particles does oxygen have?

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 atomic number 8 could have?

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.


If an atom contains 7 protons and 8 neutrons its atomic mass is?

The atomic mass of the isotope 15N is 15,000 108 898 2(7).


What is the mass number of a carbon isotope that consists of 6 protons 6 electrons and 8 neutrons?

14.


Why does beryllium have an atomic mass of 9 instead of 8?

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.


If an atom has 8 protons and 11 neutrons and 8 electrons what is the atomic mass of the atom?

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.
