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.
Because the number of protons (atomic number) of an atom NEVER, NEVER changes, you simply find the element on the Periodic Table using the number of protons they give. If the atom is neutral (no charge), the number of electrons will equal the number of protons. The element with atoms that have six protons is Carbon. Since this atom in the problem has 6 electrons, they are talking simply about a Carbon atom, not an ion.
An element is defined using the element's atomic number, which is equal to the number of protons. 6 protons = atomic number 6. This element can be located near the top of your periodic table.
Yes. It's a fairly uncommon (and radioactive) isotope of carbon.
Incidentally, for the purposes of the question the exact numbers don't really matter. Every atom is an isotope.

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.)
No. Radioactive elements are normally a result of the atom actually being an isotope of that element. An isotope is an atom of an element that has a different amount of neutrons than the norm. For example, the normal amount of neutrons in a Carbon atom is six, but Carbon-14 has eight, and Carbon-16 has ten. These isotopes are normally radioactive.
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.
There are 8 Valence Electrons.
Oxygen because its atomic number is eight
The Atomic Mass is 17
15
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.
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-.
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.
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.
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.
The element is carbon and the isotope is 6C14
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.
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.
