As an example, take Americium 241 - 241 is the atomic weight. It is Atomic number 95 in the Periodic Table and so there are 95 protons. There are thus 241 -95 = 146 neutrons. That principle applies to all the elements.
What else can I help you with?
Which of the following particles is used to determine the mass of an atom?
Mass of an atom is determined by the no. of protons+ no. of neutrons in the atom.
How many neutrons are found in one atom of rm 36Cl?
One atom of (^{36}Cl) contains 20 neutrons. This can be calculated by subtracting the number of protons (which is 17 for chlorine) from the atomic mass number (36).
If the atomic mass of an atom is 48 and the atom contains 20 protons how many neutrons does the atom contain?
If the atomic mass of the atom is 48 and it contains 20 protons, then the atom contains 28 neutrons. This can be calculated by subtracting the number of protons from the atomic mass, since the atomic mass includes both protons and neutrons.
How is the number of neutrons in an atom found?
The number of neutrons in an atom can be found by subtracting the number of protons (which is the atomic number) from the mass number. The mass number is the sum of protons and neutrons in the nucleus of an atom.
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.
Which of the following particles is used to determine the mass of an atom?
Mass of an atom is determined by the no. of protons+ no. of neutrons in the atom.
Neutrons in the nucleus of an atom calculated?
Mass number minus atomic number = number of neutrons
How many neutrons are in one atom?
The number of neutrons in one atom can vary depending on the element. Neutrons are one of the three main subatomic particles found in an atom, along with protons and electrons. The number of neutrons in an atom is calculated by subtracting the number of protons (atomic number) from the atomic mass of the atom.
What is equal to the total number of protons and neutrons?
If you add the number of protons to the number of neutrons in an atom, you have calculated that atom's atomic mass.
How many nuetrons in a sodium atom?
there are 11.99 neutrons in an atom of sodium
How many neutrons are found in one atom of rm 36Cl?
One atom of (^{36}Cl) contains 20 neutrons. This can be calculated by subtracting the number of protons (which is 17 for chlorine) from the atomic mass number (36).
What is the total number of neutrons in an atom of 0-18?
An atom of oxygen-18 has 10 neutrons. This is calculated by subtracting the atomic number (8) from the atomic mass (18).
How many neutrons are in an atom of 18O?
An atom of 18O has 10 neutrons. This is calculated by subtracting the atomic number (which is 8 in this case) from the atomic mass number (18).
The number of neutrons in the nucleus of an atom can be calculated by what?
The number of neutrons in the nucleus of an atom can be calculated by subtracting the number of protons (atomic number) from the atomic mass of the atom. Atomic mass - Atomic number = Number of neutrons.
How is the number of of neutrons in the nucleus of an atom calculated?
Subtract the number of protons from the mass number.
What mass number is calculated by adding the numbers?
the mass number of an atom is the number of protons in an atom, plus the number of neutrons.
The number of neutrons in the nucleus of a silicon atom are?
A silicon atom typically has 14 neutrons in its nucleus. This number is calculated by subtracting the atomic number (14) from the mass number (28) of silicon.
