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.
carbon; it has 6 electrons, and is neutral, so must have 6 protons. no. of protons defines the type of element (it is the atomic number) 6 is Carbon.
To calculate atomic mass, only the amount of protons and neutrons will be summed. So eight protons plus nine electrons equals seventeen atomic mass units.
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.
Oxygen because its atomic number is eight
15
The only particles with significant mass in an atom are the protons and neutrons. Each has a mass of 1 amu (equals 1 mass number). The oxygen atom with 8 protons and 8 neutrons would have a mass number of 16. The mass of the electrons is insignificant, like the flies on the elephants back.

The Atomic Mass is 17
That would be an oxygen isotope and it's Atomic Mass would be 16. (Protons + Neutrons) The mass of an electron is so minuscule that it is not even factored into the mass.

It varies depending on the atom but basically there are the same number of neutrons as there are protons. Helium has two protons, two electrons, and two neutrons. The difference between the atomic mass and the atomic number equals the atom's number of neutrons. Consider hydrogen, for example. Standard hydrogen has no neutrons, just one proton. Deuterium is an isotope of hydrogen with one neutron, and tritium (which is unstable) has two neutrons. Carbon 12 has six protons and six neutrons, but carbon 14 (which is unstable) has six protons and eight neutrons. As you move up the periodic table, nuclei tend to have more neutrons than protons. 92 U 238, for example, has 146 neutrons.

Neutrons and protons make up the nucleus; therefore, they cannot revolve around the nucleus. Electrons, on the other hand, are on orbitals surrounding the nucleus. The number of orbitals and the number of electrons per orbital depend on the placement of the element on the periodic table, the atomic mass, the atomic number, etc. A maximum of eight electrons can be on one orbital.
An atom that has eight protons, seven neutrons and nine electrons is an oxygen atom because of the eight protons, seven neutrons makes it a particular isotope of oxygen, and with nine electrons means that it is an ion with a charge of minus one, this is unusual because oxygen tends to form ions with minus two not minus one
Oxygen-16 has 8 electrons and 8 neutrons.
You put the number of protons and neutrons in the middle of the first circle (nucleus). The number of protons and electrons is the Atomic number. Round the atomic mass and subtract it by the number of protons and you have your neutrons. Draw another circle (shell) around the first one. You can only put up to two electrons in the first one. The next two circles you draw can hold up to 8. The last shell can hold 18. EG: Neon There are ten protons, neutrons and electrons. Draw the nucleus first, then write the number of protons and neutrons inside. Draw a shell around the nucleus and place two electrons side by side. Draw another shell around the first one and draw eight electrons around it.
