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)
How many neutrons are in an isotope of lithium if it has an atomic mass of ten?
An isotope of lithium with an atomic mass of ten would have an atomic number of 3, meaning it has 3 protons. To find the number of neutrons, subtract the atomic number from the atomic mass: 10 (atomic mass) - 3 (atomic number) = 7 neutrons. Therefore, an isotope of lithium with an atomic mass of ten would have 7 neutrons.
How do you find the atomic notation for an atom?
To find the atomic notation for an atom, you need to know the number of protons, neutrons, and electrons in the atom. The atomic notation includes the element symbol, atomic number, and mass number. The atomic number is equal to the number of protons in the atom, and the mass number is the total number of protons and neutrons in the atom.
What is the atomic number and atomic mass number in nitrogen -15?
The atomic number is 7. The mass number is 15. The atomic mass is 15,000 108 898 2(7).
How do you determine neutrons?
take nitrogen as an example it has an atomic number of 7 that determines the number of protons as 7 positive charges so it takes 7 negative charges (electrons) to even it out so you have 7 electrons and protons. then you take the atomic mass which is 14.01 but you can round it to 14. then you take the atomic number and atomic mass and subtract them (14-7=7) so the number of neutrons is 7.

What is nitrogens atomic number?
Nitrogen is a non meta element. Atomic number of it is 7.
How do you get number of electron of nitrogen?
Find the atomic number of nitrogen in a periodic table or other reference. (It is 7 for nitrogen.) The number of electrons in any neutral atoms is always the same as the atomic number of the atom.
What is the number of protons and neutrons in N?
The atomic number of nitrogen is 7. So there are 7 protons and 7 electrons. The number of neutrons depends on the isotope. N-14 has 7 neutrons. N-15 has 8 neutrons. Number of neutrons = Mass number - Atomic number.
How many neutrons are in an isotope of lithium if it has an atomic mass of ten?
An isotope of lithium with an atomic mass of ten would have an atomic number of 3, meaning it has 3 protons. To find the number of neutrons, subtract the atomic number from the atomic mass: 10 (atomic mass) - 3 (atomic number) = 7 neutrons. Therefore, an isotope of lithium with an atomic mass of ten would have 7 neutrons.
What element is atomic number 7?
Nitrogen is a non meta element. Atomic number of it is 7.
What is nitrogens atomic number and why?
Nitrogen's atomic number is 7. This is because nitrogen has 7 protons in its nucleus, which determines its atomic number. The atomic number defines the identity of an element and its position on the periodic table.
If a neutral atom has a mass of 15 amu and an atomic number of 7 whats the number of protons neutrons and electrons in the atom?
The atomic number of 7 indicates the number of protons, which is 7. Since the atom is neutral, the number of protons also equals the number of electrons, so there are 7 electrons. To find the number of neutrons, subtract the atomic number from the mass number: 15 (mass number) - 7 (atomic number) = 8 neutrons.
What is Nitrogens atomic number and mass and why does it have that?
atomic mass - 14 atomic number - 7 It has that because it has 7 protons (and electrons) = the atomic number. And it also has about 7 neutrons and roughly, the mass number = the number of neutrons+ the number of protons.
If an atom has 7 protons 7 neutrons and 7 electrons what would be the atomic number?
The answer is 7. The amount of protons is always the atomic number of the element. If the protons (atomic number) changes then the element changes
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.
How many protons would you expect to find in neutral nitrogen atom?
A neutral nitrogen atom has 7 protons. This is because nitrogen has an atomic number of 7 and each atom has the same number of protons as its atomic number. Therefore a neutral nitrogen atom would have 7 protons.
