How is nitrogen -15 isotope different from a nitrogen -9 isotope?
Nitrogen-15 would have 8 neutrons, while nitrogen-9 (if it existed) would only have 2.
How many protons could a stable atom with 90 neutrons potentially have?
A stable atom with 90 neutrons could potentially have a maximum of 90 protons, as the number of protons would have to be equal to or less than the number of neutrons for the atom to be stable.
What is the atomic mass number A for N with 7n?
The atomic mass number A is the total number of protons and neutrons in an atom's nucleus. For nitrogen (N), the atomic number (number of protons) is 7. If it has 7 neutrons (designated as "7n"), then the atomic mass number A would be 14 (7 protons + 7 neutrons).
Nitrogen has an atomic mass of 14 and an atomic number of 7 so the number of neutrons must be?
The atomic mass of an atom is the total mass of its particles. The atomic number is the number of protons in the atom's nucleus. To find the number of neutrons in an atom, we take its atomic mass (the total mass of its particles) and subtract its atomic number (the number of protons and electrons in the atom). A: Lithium has an atomic mass of 7 and an atomic number of 3 so the number of neutrons is equal to 4. (7 - 3 = 4)
Are most atoms their mass number is the same as their atomic number?
No. In most atoms the mass number is at least twice the atomic number. A mass number that is the same as the atomic number would indicate a nucleus with no neutrons. Such a nucleus would be highly unstable except in the case of the hydrogen-1 nucleus, which consists of a single proton. In most other stable nuclei there are at least as many neutrons as their are protons. The mass number is the sum of the number of protons and the number of neutrons.
How is nitrogen -15 isotope different from a nitrogen -9 isotope?
Nitrogen-15 would have 8 neutrons, while nitrogen-9 (if it existed) would only have 2.
What information would be requierd to determine the mass number of nitrogen?
You would need to know how many protons and neutrons are in the nucleus of a particular isotope of nitrogen. The number of protons, which is its atomic number, will always be the same, no matter which isotope is given, but the number of neutrons differs with different isotopes. For example, one isotope of nitrogen has 7 neutrons. To determine its mass number, find nitrogen on the periodic table, and you will see that its atomic number is 7. So this isotope of nitrogen has 7 protons. Now, add the 7 neutrons to the 7 protons, and you get a mass number of 14 for this isotope of nitrogen, which is called nitrogen-14. (Isotopes are named by their mass numbers.) Another isotope of nitrogen has 8 neutrons. Add the 8 neutrons to the 7 protons (atomic number), and you get a mass number of 15 for this isotope of nitrogen, called nitrogen-15.
Which information would be required to determine the mass number of nitrogen?
To determine the mass number of nitrogen, you would need to know the number of protons and neutrons in its nucleus. Nitrogen has 7 protons, so the mass number can be calculated by adding the number of protons (7) to the number of neutrons in the nucleus.
What is the number of neurons in nitrogen?
Nitrogen is an atomic element and does not have any 'neurons' because neurons are nerve cells.I think you meant 'neutrons' :-Nitrogen has an atomic mass of 14.00674 and an atomic number of 7. As the majority of mass in an atom is in the nucleus and as the atomic number represents the number of protons in the nucleus, the number of neutrons ROUGHLY = the atomic mass minus the atomic number. In other words Nitrogen would have 7 neutrons in its nucleus.The fractional part of the atomic mass is because there are isotopes of nitrogen some with more or less neutrons than 7. In fact there are two stable isotopes of nitrogen: 14N and 15N the most common is 14N (99.634%).
How many protons could a stable atom with 90 neutrons potentially have?
A stable atom with 90 neutrons could potentially have a maximum of 90 protons, as the number of protons would have to be equal to or less than the number of neutrons for the atom to be stable.
How does nitrogen radioactive differ from a stable atom?
Chemically there is no difference between radioactive nitrogen and stable nitrogen. Both will react the exact same way in all chemical reactions. The only difference between the two is the number of neutrons in the nucleus. This means the only difference is mass. If the nitrogen atom has too many neutrons, it will most likely give off a beta particle. The beta particle shoots out from one of its neutrons. That neutron then becomes a proton and the nitrogen becomes oxygen. If the nitrogen atom has too few neutrons, a proton in its nucleus may capture one of its own electrons and turn into a neutron. This would then turn the nitrogen atom into a carbon atom.
A radioactive isotope has eight neutrons Write the atomic number and mass number of this radioactive nitrogen as a chemical symbol with a subscript and superscript?
The atomic number of nitrogen is 7. When it is a radioactive isotope you add the number of neutrons to the atomic number (equaling 15). You then write 15 over 7 next to a capital 'N' representing Nitrogen.
What would happened to a stable nucleus in which the number of neutrons suddenly decreased?
The nucleus would become unstable because you need a certain amount of neutrons, electrons, and protons for it to be stable.
How many protons neutrons and electrons make up atom of nitrogen-15?
7 protons 7 electrons 8 neutrons
How can you find the number of neutrons in the isotope nitrogen-16?
Subtract the number of protons (atomic number) from the mass number 16. The atomic number of nitrogen is 7, therefore its atoms have 7 protons. The number of neutrons in the atoms of the isotope nitrogen-16 is 16 -7 = 9 neutrons.
What element has 7 protons and 3 neutrons?
Seeing the number of protons, I would guess nitrogen.
Which element has 7 protons and 8 neutron?
Elements are determined by their number of protons. Nitrogen has 7 protons but usually 7 neutrons as well. What you have here is a nitrogen isotope, an element with more or less neutrons than there are protons. Specifically, this is Nitrogen-15.
