How many protons electrons and neutrons does an atom with an atomic number of 50 and a mass number 125 contain?
Remember: p+ + n = m => n = m - p+ AND e- = p+
- p = number of protons = atomic number
- n = number of neutrons
- m = mass number = (by definition) number of protons + number of neutrons
- e- = electrons, valuable only for (neutral) atomic elements
Answer:
n = m - p+ = 120-50 = 70 neutrons in 50Sn(70), the most common isotope of tin (33%)
e- = p+ = 50 = 50 protons and 50 electrons in 50Sn(70), tin, metal element in group 14.

How many protons electrons and neutrons does an atom with atomic number 20 and a mass number 45 contain?
Atomic number 20 therefore 20 protons and 20 electrons. Mass number 45 therefore 45-20 = 25 neutrons.
What is a mixture of sub atomic particles nuclei and electrons?
An ATOM. The sub-atomic particles are Protons, Neutrons. and Electrons. The protons and neutrons are collectively named 'nucleons, because they form the nucleus of an atom. The electrons are in energy shells around the nucleus.
What is the number of protons electrons and neutrons in n-14?
Nitrogen-14: 7 Protons, 7 Electrons, 7 Neutrons To work this out in the future for other elements: Protons = Atomic Number Electrons = Atomic Number Neutrons = Atomic Mass - Atomic Number Hope this helps!
What is the number of protons neutrons and electrons in the neutral atom bromine-80?
Bromine has the atomic number 35, so it has 35 protons. To find the number of neutrons in Bromine-80, subtract the atomic number from the atomic mass: 80 (atomic mass) - 35 (protons) = 45 neutrons. Since it is a neutral atom, the number of protons and electrons are the same, so there are 35 electrons.
How many electrons protons and neutrons does rubidium have?
Its atomic # is 37 so 37 protrons and electrons as for nuetrons it is 85(atomicmass)- 37(the atomic number)=48
Is it correct that nucleus contains electrons and protons?
The atomic nucleus contain neutrons and protons.
Which particle in atom dose not contain oxygen?
An atomic nucleus contain protons, neutrons and electrons - not oxygen.
How many protons electrons and neutrons does an atom with atomic number 50 and mass 125 contain?
Protons = Atomic Number = 50 Neutrons = Atomic Mass - Atomic Number = 125 - 50 = 75
What particles make up the mass of an atom?
The number of protons
What are the number of protons neutrons and electrons in an element?
Number of protons = Number of electrons = Atomic number Number of neutrons = Atomic number - Number of protons
What are the subatomic particles in atomic structure?
The subatomic particles in an atom are protons, neutrons, and electrons. Protons and neutrons are found in the nucleus of the atom, while electrons orbit around the nucleus in various energy levels or shells.
How many protons neutrons and electrons are found in phosphorous?
Phosphorus has an atomic no. of 15 and its atomic mass is 31.=we know,atomic no.=number of protons==also, atomic mass=no.of protons+no. of neutrons==this implies, 31=15+no. of neutrons= 31-15=no. of neutrons= 16=no. of neutrons==also,no. of protons=no, of electrons=so, total no. of protons=15total no. of electrons=15total no. of neutrons=16
Atomic particles located in the nucleus?
Neutrons and protons.
What is the number of protons in the necleus?
# of protons = # of electrons # of protons/ electrons + # of neutrons = atomic mass
How many protons electrons and neutrons does an atom with atomic number 20 and a mass number 45 contain?
Atomic number 20 therefore 20 protons and 20 electrons. Mass number 45 therefore 45-20 = 25 neutrons.
