How many neutrons does carbon have if it has a Mass Number of 12?
If carbon has a mass number of 12, it means it has 6 protons (since the atomic number of carbon is 6). To find the number of neutrons, you subtract the number of protons from the mass number. Therefore, carbon-12 would have 6 neutrons.
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 in magnesium?
The "25" is the mass number, which is the sum of the number of neutrons and protons. We don't know how many neutrons there are, but we do know how many protons magnesium has. The atomic number of an element is the same as the number of protons, so locating a Periodic Table, magnesium is number 12, which means 12 protons. If mass number = number of protons + number of neutrons, then number of neutrons = mass number - number of protons (or atomic number). So 25 - 12 = 13 neutrons in 25Mg.
How many neutrons are present in a magnesium atom with a mass number of 24?
A magnesium atom with a mass number of 24 has 12 protons because the atomic number of magnesium is 12. To find the number of neutrons, you subtract the atomic number from the mass number: 24 (mass number) - 12 (atomic number) = 12 neutrons.
What is the mass number of a magnesium atom with 14 neutrons?
The mass number is the sum of protons and neutrons in an atom. Since magnesium has 12 protons, a magnesium atom with 14 neutrons would have a mass number of 26 (12 protons + 14 neutrons = 26 mass number).
How many neutrons are in magnesium 25?
25 is the number of protons and neutrons added together. The atomic number of Mg is 12 which is the number of protons. So 25 - 12 = 13 neutrons.
How many neutrons are in an atom of sodium with mass number 23?
An atom of sodium with mass number 23 has 12 neutrons. This can be calculated by subtracting the atomic number (which is 11 for sodium) from the mass number (which is 23).
How many protons and neutrons does a carbon atom with a mass number of 12 have?
A carbon atom with a mass number of 12 has 6 protons (which is the atomic number of carbon) and 6 neutrons.
How many neutrons are in an atom sodium with mass number 23?
12
What is the mass number of an atom with 11 protons 11 electrons 12 neutrons?
Sodium is a metal element. Mass number of it is 23.
What is the number of neutrons in an atom with atomic number 12 and mass number 22?
Number of neutrons = Mass number - Atomic number = 22 - 12 = 10
How many neutrons are found in an atom of aluminum-27?
Number of neutrons = Mass number - Number of protons = 26 - 12 = 14 neutrons
