What does the number of neutrons determine?
they determine the atomic mass of the atom
How can you determine the number of neutrons in an atom if its mass number and its atomic number are known?
It is impossible to determine the number of neutrons from the mass number and atomic mass, since the two are essentially same value. However, with the atomic number and the mass number, one can calculate the number of neutrons by subtracting the atomic number from the mass number.
How do you find the number of neutrons from the mass number?
Atomic mass is the number of protons in an atom mass number is the number of protons plus neutrons in an atom the number of neutrons would equal the mass number minus the atomic number.
What equals the number of neutrons plus the number of protons in an atom?
The mass number is a whole number that is equal to the sum of protons and neutrons in an atom. Mass number is represented by the letter (A) orA= Z + N (Z) represent the atomic number or the number of protons in the nucleus.
How many neutrons are there in an element having a mass number of 155 and an atomic number of 63?
The number of neutrons in the nucleus of an atom is always the difference between the mass number of the atom and the atomic number of the atom. Therefore, in this instance, there are (155 - 63) or 92 neutrons in the atom.
What is the number of neutrons in an atom affects the atomic what?
The number of neutrons in an atom can affect the atomic mass of an atom.
What does the number of neutrons determine?
they determine the atomic mass of the atom
What number is the atomic mass equal to?
Atomic mass is the number of protons and neutrons in an atom.
What do you have when you subtract the atomic no from atomic mass?
Atomic number is number of protons in an atom while atomic mass is the sum of protons and neutrons in an atom when you subtract you will get the number of neutrons in an atom.
Atomic mass is determined by the number of protons plus the number of?
Atomic mass is determined by the number of protons and neutrons in an atom's nucleus.
How can you determine the number of neutrons in an atom if its mass number and its atomic number are known?
It is impossible to determine the number of neutrons from the mass number and atomic mass, since the two are essentially same value. However, with the atomic number and the mass number, one can calculate the number of neutrons by subtracting the atomic number from the mass number.
What do you get if you subtract the atomic number from the mass number for a particular atom?
mass no - atomic no = number of neutrons in an atom.
Is atomic mass the amount of neutrons in the nucleus in the atom?
atomic mass = number of neutrons + number of protons.
How do you find the number of neutrons from the mass number?
Atomic mass is the number of protons in an atom mass number is the number of protons plus neutrons in an atom the number of neutrons would equal the mass number minus the atomic number.
How is the number of neutrons in an atom found?
The number of neutrons can be calculated if the atomic number and mass number of an element is known. The number of neutrons = Mass number - atomic number.
How is an atomic number similar to mass number?
The nucleus of an atom consists of protons and neutrons. The number of protons in a particular nucleus is its "atomic number". The total number of protons and neutrons in a particular nucleus is its "mass number".
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)
