How many protons does an atom with the atomic number 50 and mass number of 125 contain?
This would contain 50 protons.
How many proton's neutrons and electrons of Pb are present with a mass number of 207 and an atomic number of 82?
atomic mass equal to number of protons and neutrons. If Pb has a mass of 207 and an atomic number of 82, that means that there are 82 protons in Pb, which also means there should be 82 electrons. That leaves neutrons, which would be 207-82=125 neutrons.
How many neutrons are in the atom pb?
You take the atomic mass (the small number in the upper left corner of the square in the periodic table) and subtract the atomic number from it (the big bold number on the periodic table)
How many protons electrons and neutrons does an atom with an atomic number of 50 and mass number of 125?
If its a neutral atom, there will be the same number of protons as electrons. The atomic number will tell you how many protons there are, so there are 50 protons and 50 electrons.The mass number is the sum of the number of protons (or electrons in a neutral atom) and the number of neutrons. Since we know there are 50 protons, we subtract 125 with 50 to get 75 neutrons.
How many electrons protons and neutrons are in lead?
Lead, atom number 82, has 4 natural occurring isotopes Pb-204, 206, 207 and 208.They all have 82 protons and 82 electrons.The neutron number varies from 122, 124, 125 and 126 respectively.(Remember: atom number = p+ = e- and mass number = p+ + n0 )Pb-207 has 82 protons, 82 electrons and 125 neutrons
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
How many neutrons are in the average atom having an atomic mass of 207.2 grams per mole?
Look on the periodic table for the element with the closest atomic mass to that number. It's lead (Pb, #82.) Now, for the neutron count, you round that atomic mass to the nearest whole number, which is 207, then subtract the atomic number of 82 from it. 207-82=125. So 125 neutrons.
How many protons does an atom with the atomic number 50 and mass number of 125 contain?
This would contain 50 protons.
What is the atomic mass for 125 pounds?
125 lbs. = 3.414e+28 amu
How many proton's neutrons and electrons of Pb are present with a mass number of 207 and an atomic number of 82?
atomic mass equal to number of protons and neutrons. If Pb has a mass of 207 and an atomic number of 82, that means that there are 82 protons in Pb, which also means there should be 82 electrons. That leaves neutrons, which would be 207-82=125 neutrons.

How many electrons are in lead outer shell?
82. Lead is an element with symbol Pb and atomic number 82. The atomic number relates to the amount of electrons of the element
What is the atomic number for isotope magnesium-125?
We can find Magnesium as a metal element. Atomic number of it is 12.
How many electrons protons and neutrons are in lead?
Lead, atom number 82, has 4 natural occurring isotopes Pb-204, 206, 207 and 208.They all have 82 protons and 82 electrons.The neutron number varies from 122, 124, 125 and 126 respectively.(Remember: atom number = p+ = e- and mass number = p+ + n0 )Pb-207 has 82 protons, 82 electrons and 125 neutrons
How many protons electrons and neutrons does an atom with an atomic number of 50 and a mass number 120 contain?
The atomic number 50 corresponds to the element tin, or Sn.The atomic number tells you the number of protons, which is 50 protons.The mass number is equal to the number of protons + the number of neutrons.So 55 - 50 = 5 neutronsAnd a neutral atom has exactly the same number of protons as electrons, so it has 50 electrons.
How do yo find the neutrons of an atom?
Refer to the periodic table of elements the number above the letter (atomic #) refers to the number of protons in the nucleus NOTE: in a neutral atom, we know that #protons = #electrons the number below the letter(atomic mass) refers to the number of protons + neutrons therefore if we take ATOMIC MASS - ATOMIC # = # NEUTRONS
