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)
An atom has 13 protons and an atomic mass of 27 How many neutrons does this atom have?
The atom in question has 13 protons, so is atomic number 13, which is Aluminium. Assuming that all of the atom's mass is formed from the protons and neutrons, and each of these have atomic mass 1, the number of neutrons is 27 - 13 = 14 neutrons. Almost all Aluminium is of this isotope.
What is the atomic mass of flourine-14?
The atomic mass of fluorine-14 is 14 atomic mass units (amu). It is determined by the total number of protons and neutrons in the nucleus of the fluorine-14 atom.
What is the mass number of the most common silicon atom?
The most common silicon atom has a mass number of 28. This means it has 14 protons and 14 neutrons in its nucleus, giving it an atomic mass close to 28 atomic mass units.
How many neutrons does a carbon atom have with the mass number of 14 and an atomic number of 6 have?
A carbon atom with a mass number of 14 and atomic number of 6 will have 8 neutrons, calculated by subtracting the atomic number from the mass number. The mass number represents the sum of protons and neutrons in the nucleus of an atom, and the atomic number indicates the number of protons, which in this case would be 6 for carbon.
A neutral atom contains 12 neutrons and 14 electrons. The mass number and the number of atom are respectively?
The mass number is 26. This is the isotope silicon-26 with the atomic number 14.
An atom of aluminum (Al) has an atomic number of 13 and a mass number of 27. How many neutrons does it have?
an element always has as many electrons as protons...... the Atomic Number equals the number of protons. So if your atomic number is 13......you have thirteen protons.....and therefore 13 electrons
How is the atomic mass of an element used to determine the number of nuetrons in its atom?
Different isotopes of the same element have different numbers of neutrons but the same number of protons. The sum of the protons and neutrons is called the mass number. If you know the mass number and the number of protons (which is the atomic number), then you simply subtract the protons (or atomic number) from the mass number and the result is the number of neutrons. Example: Carbon-14 has a mass number of 14. Carbon's atomic number (and number of protons) is 6. So, 14 - 6 = 8 neutrons.
How many neutrons are in a silicon atom with an atomic mass of 28?
There are 14 neutrons.Atomic Mass is the total amount of neutrons and protons that are contained within an atom's nucleus.So, if you are given the atomic mass, proton count, neutron count, or electron count, then you can find out the approximate any of those values algebraically.And remember that atomic mass has decimals since it is the average of all the element's isotopes.
What is the mass of an atom with 13 protons and 14 neutrons?
The mass of an atom is primarily determined by the sum of its protons and neutrons. To find the mass of an atom with 13 protons and 14 neutrons, add the total number of protons and neutrons together: 13 protons + 14 neutrons = 27. The approximate mass of this atom would be 27 atomic mass units (amu).
An atom has 14 protons and 13 neutrons what it its atomic mass?
The atomic mass is the sum of the number of protons and neutrons in an atom. In this case, the atomic mass would be 14 (protons) + 13 (neutrons) = 27.
How is the mass number related to an atom related to the number of neutrons?
The mass number is the total number of protons and neutrons in an atom's nucleus. The number of protons is the same as the element's atomic number, so the number of neutrons is the mass number minus the atomic number. The mass number can be determined by rounding the atomic weight to the nearest whole number. Also, the mass number is given as part of an isotope's name, for instance: Carbon-14 has a mass number of 14.
