P or Phosphorous occurs naturally as 31P and has 16 neutrons. There are two synthetic isotopes which are 32P and 33P which have 17 and 18 neutrons, respectively, but both do not occur naturally in nature and have half-lives of around half a month to a month.

The number of neutrons in an atom of an element can be calculated by subtracting the atomic number (number of protons) from the mass number. For example, in phosphorus (P), which has an atomic number of 15 and a mass number of around 31 (most common isotope), the number of neutrons would be around 31 - 15 = 16 neutrons.

How many neutrons does U-235 have?
Uranium 235 has 92 protons and 92 electrons. To find the number of neutrons, follow this equation: Mass # - Atomic # = # of neutrons. Since the mass number of uranium 235 is 235 and has an atomic number of 92, the number of neutrons is 143.
Titanium 48 has how many neutrons?
Number of neutrons is 48 (mass number) minus 21 (proton number) = 27 (neutron number)
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 the number of neutrons in an atom affects the atomic what?
The number of neutrons in an atom affects the atomic mass of an element. Neutrons contribute to the overall mass of the atom but do not affect its chemical properties.
How many neutrons are there in iodine?
There are varying isotopes of iodine, but typically an iodine atom has 74 neutrons.
To find the number of neutrons is an isotope start with the mass number and what?
To find the number of neutrons in an isotope, subtract the atomic number (number of protons) from the mass number (sum of protons and neutrons). The difference will give you the number of neutrons in the nucleus.
The mass of a Cr is 52 amu its atomic number is 24 how many neutrons are in its nucleus?
Since n + p = m, it follows that neutrons = 54 - 24 = 30,because number of protons (p) is the atomic number (34)! That's how the periodic table is organized.
How do you find the atomic number of an element by looking at it's isotopes?
The mass of one specific isotope, called the mass number, is the total number of protons plus neutrons. M = P + NTherefore, for atomic number P, you would take the mass number minus the neutrons: P = M - N.
The mass number minus the atomic number is?
The number of neutrons in the nucleus is not the answer its wrong trust me Mass number = neutrons + protons. Atomic number = protons. Trust yourself to work out the difference.
How many neutrons does a phosphorus-32 atom have?
how many neutrons there are in a phosphorus atom? The normal isotope of phosphorus is P - 31, which has 15 protons and 16 neutrons. Unstable isotopes are P-32 and P-33 which have 17 and 18 neutrons respectively.
How do the mass number and the atomic number of an element different?
Atomic number equals the number of protons, the (atomic) mass number equals the sum of (the number of) protons and neutrons of the same element.The answer is: they're differing in the number of neutrons(Mathematically: Where A = p and M = p + n, the difference in A and M is n)
How do you find the ratio of neutrons to protons?
The ratio of neutrons to protons in an atom can be calculated by subtracting the atomic number (number of protons) from the atomic mass (sum of protons and neutrons) of the atom. Mathematically, ratio of neutrons to protons = (Atomic mass - Atomic number).
What is the average number of neutrons found in the atom gold?
Substract the atomic number (= number of protons) of Au (element) from the average atomic mass (= total number of protons and neutrons) of Au (mixture of isotopes, as been found in nature). This will give you a good approximation of what you asked. So: -79 (p) + 197,0 (n + p) = 108 neutrons
Which element has 30 neutrons and 15 electrons?
The element with 30 neutrons and 15 electrons is phosphorus. The number of neutrons in an element is determined by subtracting the atomic number from the atomic mass. Since phosphorus has an atomic number of 15 and an atomic mass of approximately 31, it has 30 neutrons.
How do the mass numbers and the atomic numbers of an element differ?
Atomic number equals the number of protons, the (atomic) mass number equals the sum of (the number of) protons and neutrons of the same element.The answer is: they're differing in the number of neutrons(Mathematically: Where A = p and M = p + n, the difference in A and M is n)
What is the number of neutrons for Li?
Subtract number of protons (=atomic number) 3 from the total number of protons AND neutrons ( p+n = mass number) 7, leaves the number of neutrons 47-3=4
How many protons and neutrons are in the nucleus of isotope with mass of 70.925 amu?
p,n =31,38 P=31 (from Periodic Table) N= 68.926-31=37.926
