Does carbon 12 and carbon 14 have the same atomic number?
Does carbon 12 and carbon 14 have the same atomic number?
Explanation: Carbon exists in several isotopes. The most common of these is carbon 12, 13, 14. All of these isotopes have the same atomic number but different mass numbers.
Why are carbon 14 and carbon 12 considered to be isotopes?
Isotopes are forms of the same element with equal numbers of protons but different numbers of neutrons. For example, both carbon-12 and carbon-14 have 6 protons. But carbon-12 has 6 neutrons while carbon-14 has 8 neutrons. By definition, carbon-12, carbon-13 and carbon-14 are all isotopes of the carbon.
Why is nitrogen 14 not an isotope?
What do all isotopes of an element have in common? Explain why carbon-14 and nitrogen-14 are not considered isotopes of each other? Because they are two different elements. Same mass number but different atomic number.
What does the 14 mean in nitrogen-14?
Isotopes are atoms that have the same number of protons but different numbers of neutrons in the nucleus. The mass number of an isotope is added to the name of the isotope. In this case, you have. nitrogen-14⇒mass number=14. The mass number of an atom tells you the number of protons and neutrons located in the nucleus.
Which nitrogen is more abundant?
The most abundant naturally occurring gas is Nitrogen (N2), which makes up about 78% of air. Oxygen (O2) is the second most abundant gas at about 21%. The inert gas Argon (Ar) is the third most abundant gas at . 93%.
What happens if there are more neutrons than protons?
Stable isotopes of the heavier elements (top right of the graph) have more neutrons than protons. For example, Gold-197 is stable. It contains 79 protons and 118 neutrons. The neutrons in a nucleus can be thought of as acting as a kind of glue to hold the nucleus together.
How many protons neutrons and electrons are in nitrogen?

What isotope has 25 protons and 15 neutrons?
#25 – Manganese – Mn.
What element has a mass number of 24 and 11 protons?
Sodium has a mass number of 23amu. Since sodium has 11 protons, the number of neutrons must be 23 – 11 = 12 neutrons.
What element has the atomic mass of 7?
Nitrogen
