The Atomic Mass is the number of protons, plus the number of neutrons. In this case, 8 + 6 = 14.
Furthermore, the six protons (atomic number) tells me that this is carbon; the six electrons tell me that this is a carbon atom, rather than a carbon ion (an ion is when the number of electrons does not equal the number of protons, making the atom electrically non-neutral). The eight neutrons tell me that this is an isotope (in other words, a version) of carbon called carbon-14, which happens to be mildly radioactive; and therefore useful to archaeologists in dating human artifacts.
Any atom with 8 protons is an oxygen atom. Seven neutrons makes it a particular isotope of oxygen, and nine electrons means that it is an ion, with a charge of minus one. This is unusual because oxygen tends to form ions with a charge of minus two, not minus one, but it isn't impossible.
If an atom, let's say oxygen, has an equal amount of protons (8, positive charge) and electrons (8, negative charge), it's completely NORMAL. See, the atomic number IS the number for the protons and electrons (i.e: Oxygen's atomic number is eight, therefore its protons and electrons would also be eight.)
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
A krypton atom has 8 valence electrons in the 4s and 4p orbitals.
8 valence electrons are needed for an element to become stable, which is why the noble gases do not interact with any other elements. They are already stable. However, the exception is Helium, the first noble gas, which only has two valence electrons. 8 valence electrons are needed on the 2nd and 3rd valence shells for any molecule to become stable.
The atomic mass of the element with eight protons and nine neutrons is 17 atomic mass units. This is calculated by adding the number of protons and neutrons together, as electrons contribute negligible mass to the overall atomic mass.
The element that has 9 protons is fluorine. Its atomic number is 9, indicating that the element has 9 protons in the nuclei of its atoms. If there are 10 electrons, then the fluorine atom has gained an electron and is now a negatively charged anion with a charge of 1-.
The Atomic Mass is 17
The atomic mass of an element is the sum of the number of protons and neutrons in the nucleus of an atom. In this case, the element has 7 protons and 8 neutrons, so the atomic mass would be 7 + 8 = 15 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.
The element with 8 protons is oxygen (symbol O). It normally has 8 electrons as well, but in this case it has one extra electron, making it an ion. With 7 neutrons, the ion is known as oxygen-15.
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.
The atomic weight of an element is the weighted average of the masses of its isotopes. For an element with 8 protons and 8 neutrons (oxygen-16 isotope), the atomic weight would be close to 16 g/mol due to the equal number of protons and neutrons.
When we consider charged particles, we are only concerned with protons and electrons. Neutrons have no charge, so they don't contribute to a positive or negative charge. Protons have a positive charge and electrons have a negative charge. They are both equally positive and negative, that is to say one proton cancels out the charge of one electron. So as long as there are equal numbers of protons and electrons, the particle will be neutral. If there are six protons, then there needs to be six electrons in order to be neutral.
The element is carbon and the isotope is 6C14
Oxygen-16 has 8 electrons and 8 neutrons.
An atom is the basic unit of matter consisting of a nucleus (protons and neutrons) surrounded by electrons. Two examples of atoms are hydrogen, which has one proton and one electron, and oxygen, which has eight protons, eight neutrons, and eight electrons.
