1)nitrogen
2)silicon
3)carbon
4)magnesium
i thought it was carbon but it is marked wrong on my paper. is it nitrogen? please help
also, please tell me why...??
thanks

Carbon-14
Carbon 14 has 6 protons and 8 neutrons.
Carbon 14 is actually a mutated form of Nitrogen created in the upper atmosphere when high speed nuclear particles from space collide with a Nitrogen nucleus (which has 7 protons and 7 neutrons)
One of the protons gets converted to a neutron and proton also gets kicked out of the Nitrogen nucleus. The product is Carbon-14
n + N(14) --> C(14) + H(1)
I'll spank your teacher for $20

carbon.
The element is determined by the atomic number. Thus if the atomic number is 6, the element is carbon. And the atomic number equals the number of protons.
The mass number is the total number of particles in the nucleus. Since the atomic number is 6, its carbon, and the other 8 particles are called neutrons. Thus add together to get 14 total particles in the nucleus of this isotope of carbon. It is the carbon-14 isotope, has 6 protons, and 8 neutrons.
Note: by comparison, carbon-12 has 6 protons and 6 neutons. Carbon-13 would have 6 protons and 7 neutrons. etc.
An "isotope" is simply an atom with a specific number of protons and neutrons in it. All elements have at least some isotopes. They take an average of the abundance of these isotopes found in nature, and calculate the atomic weight for each element based on that. Thus, atomic weight usually is something like, for example, 35.45, instead of a simple whole number.
Maybe your teacher made a mistake when grading your paper. Take it to him and show him again. Your answer was, and still is, right.

The answer is 3) carbon. The only element with an atomic number of 6 is carbon. C-14 is a radioactive isotope of carbon used in dating of once living things.The mass number 14 includes 6 protons and 8 neutrons.

Has to be a grading error.
If it has an atomic number of 6, it's carbon. Period. End of story.
If the mass number is 14, then it is the isotope carbon-14

It is carbon.
Atomic Number : 6
Atomic Mass : 12.0115
Melting Point : 3550 degC
Boiling Point : 4200 degC
Density : 2.25 (graphite)
There are two stable Isotopes of carbon, having mass numbers 12 and 13, and four radioactive isotopes (mass numbers 10, 11, 14, and 15).
Carbon-14 is used in carbon dating.

It's carbon. It is the only element that has an atomic number of 6.

Number of Protons = Atomic Number Number of Electrons = Number of Protons = Atomic Number Number of Neutrons = Mass Number - Atomic Number

It looks like your teacher made a mistake. The atomic number of an atom is equivalent to the number of protons in the atom's nucleus. Carbon is the ONLY atom with six protons in its nucleus, so it should be the right answer. Go to your teacher and ask her/him.
