Only protons and neutrons have 1 unit mass each, which form the nucleus. The Electrons that orbit the nucleus are of negligable mass. Therefore; total mass = 9 protons + 10 neutrons = 19 unit mass. Wiki User

The element described is fluorine. The reason that it is fluorine is because it has 9 protons, which defines the element, and which is its atomic number on the Periodic Table. Every element has its own unique number of protons which is its atomic number.   Wiki User

This is an Oxygen-17 isotope.
Isotopic mass = 16.9991315 u. (Approximately equal to no. of protons + no. of neutrons = 8 +9 = 17)

9: The atomic number of an element or an atom of the element is always the same as the number of protons in the nucleus of an atom of the element.   Wiki User

mass number = number of protons + number of neutrons = 8 + 9 = 17

so mass will be 17 amu   Wiki User

The atom is Flourine

Mass Number = no. of nucleons in the atom = no. of protons + no. of neutrons

A = 9 + 10 = 19   Wiki User

Protons and neutrons each weigh 1 a.m.u., so 8+9=17. The 10 electrons do not contribute significantly to the Atomic Mass. This would be an isotope of oxygen.   Wiki User

### What are the number of protons neutrons and electrons in an element?

Number of protons = Number of electrons = Atomic number Number of neutrons = Atomic number - Number of protons

### How do you determine the number of protons electrons and neutrons present in an element by identifying its atomic and mass numbers from the periodic table?

Atomic number means number of protons present in an atom. Atomic number= number of protons. mass number = number of neutrons+ number of protons. So if you subtract the number of protons you get neutrons and if you subtract neutrons you get protons. mass number - protons= neutrons Mass number - neutrons = protons.

### What can be determined by looking at the atomic number of an element?

the number of protons in an atom and the number of electrons in an atom

### How do you get the atomic number and weight?

No. of protons=No. of electrons = Atomic number. No. of protons + No. of neutrons = Atomic mass.

### How many protons neutrons electrons atomic number and atomic mass does bromine have?

Protons - 35 Neutrons - 43 Atomic Number - 35 Electrons - 35

### What is the number of protons electrons and neutrons in n-14?

Nitrogen-14: 7 Protons, 7 Electrons, 7 Neutrons To work this out in the future for other elements: Protons = Atomic Number Electrons = Atomic Number Neutrons = Atomic Mass - Atomic Number Hope this helps!

### What is the number of protons in the necleus?

# of protons = # of electrons # of protons/ electrons + # of neutrons = atomic mass

### How many protons neutrons and electrons are in beriyllium?

Berilyllium 'Be' has 4 protons and electrons (atomic number), it has 5 neutrons (mass number minus atomic number) :)

### How many protons electrons and neutrons in bromine-80?

79? I'm pretty sure the atomic mass of Bromine is 80. Incase you were wrong, the Atomic mass = Number of protons + Neutrons, which is 80. The atomic number is 35, which is the number of protons. Protons = 35. So the No. of Neutrons = 80 ( protons &amp; neutrons) - 35 (protons) = 45 ( No. of neutrons) and Finally for electrons = the number of protons which is 35.

### Protons electrons and neutrons in any given atom?

The atomic number of a chemical element is equal to the number of electrons or protons. The number of neutrons = Atomic weight of an isotope (rounded) - atomic number of the element (or the number of protons)
