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 can affect the atomic mass of an atom.
How many neutrons are there in iodine?
Number of neutrons = Mass number - Number of protons = 127 - 53 = 74
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 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).
An isotope of an unknown element has 17 neutrons and a mass number of 32. What is the symbol of this isotope?
To find the symbol of the isotope, we first determine the number of protons by subtracting the number of neutrons from the mass number. Since the mass number is 32 and there are 17 neutrons, the number of protons is 32 - 17 = 15. The element with 15 protons is phosphorus (P). Therefore, the symbol for this isotope is ( \text{P} ) with a mass number of 32, written as ( \text{P-32} ).
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?
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 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 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 in ca?
For Ca isotope 40 it is 20 neutrons and 20 protons, but there are 5 other naturally occurring (>2%) Ca-isotopes with mass numbers ranging from 42 - 48. Remember: p + n = mass number, so n = m - p
