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.

### To find the number of neutrons is an isotope start with the mass number and what?

The mass number of an isotope is the number of neutrons and protons in the isotope, let this be p +n = (mass number). To find the number of neutrons you need the atomic number (number of protons), let this be p. You then subtract the two: mass number - atomic number = no. of neutrons p + n - p = no. of neutrons = n

### How do you find the ratio of neutrons to protons?

You find the number of neutrons, N You find the number of protons, P Then the ratio is N:P.

### 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 neutrons are there in an atom of 32p?

Phosphorus-31 contains 16 neutrons, 15 protons and it is Stable

### 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 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 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.

### Which element has 30 neutrons and 15 electrons?

There are a variety of isotopes that have 30 neutrons. It isn't the number of neutrons that determines an element, but the number of protons. Electrons generally balance the number of protons.

### 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

### 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)

### Mass number of ununhexium?

Number of neutrons = Atomic mass of a given isotope of Uuh - 116 116 is the number of protons. Mass number = p + n Uuh-290 has 174 neutrons. The mass number is 290. Uuh-291 has 175 neutrons. The mass number is 291. Uuh-292 has 176 neutrons. The mass number is 292. Uuh-293 has 177 neutrons. The mass number is 293.
