How would you explain how to determine the number of neutrons and atom contains if you know its mass and its atomic number?
SHow your work
To find the number of neutrons in an atom you would subtract what?
You would subtract the atomic number from the mass number.
What is the atomic number of an atom contains 40 protons 40 electrons and 51 neutrons?
The atomic number is the number of protons in the nucleus which, for a neutral atom, would be 32.
If an atoms contains 11 protons and 12 neutrons its atomic number is?
The atomic number is determined by the number of Protons. So in this case it would be 11 (Sodium). The mass number is the total of protons and neutrons, so in this case 23. So this isotope of sodium would be 23Na.
What element has atomic mass of 16 and 8 neutrons?
If you had looked in the periodic table, you would have seen that the element Oxygen has an atomic mass of 16 (or more precisely 15.9994) and if you were to take that atomic mass and subtract the atomic number from it (i.e. 8) you would get a difference of 8 which is the number of neutrons it contains. In short, oxygen is that element.
Phosphorus has an atomic mass of 31 and an atomic number of 15 the number of neutrons must be?
Mass number = no. of protons + neutrons Atomic number = no. of protonsThus (mass number - atomic number) gives you no. of neutrons.Therefore for phosphorus, the number of neutrons would be 16.
Sn isotope of oxygen has an atomic number of 8 and an atomic weight of 18. how many neutrons does it have?
The atomic number of an isotope is the number of protons it contains, whereas the mass number is the total mass of the nucleus, which is the combined number of protons and neutrons in the nucleus. To find the number of neutrons, you must therefore subtract the atomic number of the isotope from the mass number of the isotope.In the above example, the atomic number is 8 and the mass number is 18. This isotope is known as O18. The number of neutrons in the isotope is: Mass number - Atomic number = Number of neutrons18 - 8 = 10
How do you find the number of neutrons from the mass number?
Atomic mass is the number of protons in an atom mass number is the number of protons plus neutrons in an atom the number of neutrons would equal the mass number minus the atomic number.
If an atom has an atomic namber of 20 and a mass namber of 53 how many protons and neutrons does that atom have?
uh, for one thing mass and atomic nUmbers. and the other: it has 20 protons and 33 neutrons. The atom would have 20 protons and 33 neutrons. The number of protons is always the same as the atomic number. To find the number of neutrons, you simply subtract the atomic number from the atomic mass. Atomic mass - Atomic number = number of neutrons (53 - 20 = 33) If you add the number of protons and the number of neutrons together, you should get the atomic mass.
What is the atomic number and atomic mass number for an isotope of Lu with 106 neutrons?
The atomic number of an element is the number of protons in the nucleus. For the element Lu (lutetium), the atomic number is 71. The atomic mass number is the sum of the number of protons and neutrons in the nucleus. Therefore, an isotope of Lu with 106 neutrons would have an atomic mass number of 177 (71 protons + 106 neutrons = 177).
How can you find the number of neutrons in the isotope nitrogen-16?
Subtract the number of protons (atomic number) from the mass number 16. The atomic number of nitrogen is 7, therefore its atoms have 7 protons. The number of neutrons in the atoms of the isotope nitrogen-16 is 16 -7 = 9 neutrons.
What would you do if you wanted to know the number of neutrons in an atom of a given element?
Neutrons, like protons are considered to have a mass of about 1. To find the number of neutrons, subtract the atomic number from the atomic mass.
