How many protons does an atom with the atomic number 50 and mass number of 125 contain?
An atom with atomic number 50 contains 50 protons. The mass number of 125 indicates the total number of protons and neutrons combined, so subtracting the number of protons (50) from the mass number gives 75 neutrons.
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.
If an element has a mass number of 208 and an atomic number of 83 how many neutrons does the element have?
To determine the number of neutrons, subtract the atomic number from the mass number. In this case, 208 - 83 = 125 neutrons.
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 numbern = number of neutronsm = mass number = (by definition) number of protons + number of neutronse- = electrons, valuable only for (neutral) atomic elementsAnswer: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 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 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.

What is the mass number of this lead atom?
... that each atom of lead contains 82 protons in its nucleus.
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.
What is the atomic mass for 125 pounds?
The atomic mass is a property that refers to the average mass of an atom of an element. It is measured in atomic mass units (amu) or grams per mole. The atomic mass is not directly related to pounds, which is a unit of weight in the imperial system.
What is the total number of neutrons in an atom of 207 82 PB?
The atomic number of lead (Pb) is 82, which represents the number of protons. To find the total number of neutrons, subtract the atomic number from the mass number. For lead-207 (207Pb), the mass number is 207. Therefore, the total number of neutrons in an atom of 207 82 Pb is 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.
