How many neutrons are in an atom with the mass number being 186?
The atomic number (number of protons) of the element is needed to tell the number of neutrons. Mass number = atomic number + number of neutrons.
Which subatomic particles makes up most of the mass off the atom?
The major contribution to the mass of an atom is from protons and neutrons; electrons have a known but negligible mass.
How many neutrons does an atom of U-251 have?
Number of neutrons = Mass number - Atomic number = 251 - 92 = 159
How many protons and neutrons are in the nucleus of the atom?
No it is not the atomic number. We call it mass number.
How can you determine the number of neutrons in an isotope?
One doesn't generally "calculate" the number of neutrons. The number of neutrons in an atom is always equal to the number of protons, and the number of protons can be found on the Periodic Table of Elements, which can easily be found on the internet or in a science textbook.
What is the sum of protons and neutrons in an atom?
Mass number!:)
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.
How do you tell how many neutrons are in an atom with the atomic number of 12?
To find the number of neutrons in an atom with an atomic number of 12 (which is the number of protons), you would subtract the atomic number from the atomic mass number. The atomic mass number is the sum of the protons and neutrons in the atom. For an atom with an atomic number of 12, the number of neutrons can be calculated by subtracting 12 from the atomic mass number given for that specific atom.
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.
How many neutrons are there in a zinc atom with a mass number of 66?
For a zinc atom with a mass number of 66, the number of neutrons can be calculated by subtracting the atomic number (30 for zinc) from the mass number. Therefore, there are 36 neutrons in a zinc atom with a mass number of 66.
How do you find out how many neutrons a atom has?
Mass number = Atomic number (or number of protons) + Number of neutrons
How many neutrons does an atom of nitrogen have if the mass number is 13?
6 neutrons
How many neutrons are in an Osmium atom of mass number 188?
An Osimum atom with mass number 188 has 118 protons (atomic number for Osmium). To find the number of neutrons, we subtract the atomic number from the mass number: 188 - 118 = 70 neutrons.
What is the mass number of 10 protons and 10 neutrons?
20. the mass of an atom is determined by the sum of the number of neutrons and protons the atom has.
Is the number of neutrons in an atom known as its mass number?
No, neutrons + protons = mass
Mercury has an atomic number of 80 and a mass number of 200 How many neutrons are in one atom of mercury?
In one atom of mercury with a mass number of 200, there are 120 neutrons (mass number - atomic number = number of neutrons).
What is the total amount of protons and neutrons in an atom?
The total amount of protons and neutrons in an atom is its mass number.
