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?
An atom with an atomic number of 50 has 50 protons and 50 electrons. To find the number of neutrons, subtract the atomic number from the mass number: 125 (mass number) - 50 (atomic number) = 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?
An atom with an atomic number of 50 contains 50 protons and 50 electrons. The mass number of 125 indicates the total number of protons and neutrons in the nucleus. Therefore, the atom contains 75 neutrons (125 - 50).
How many proton's neutrons and electrons of Pb are present with a mass number of 207 and an atomic number of 82?
In lead (Pb), the atomic number represents the number of protons, so there are 82 protons since the atomic number is 82. Given the mass number (207), which is the sum of protons and neutrons, subtracting the atomic number from the mass number gives the number of neutrons, which is 207 - 82 = 125 neutrons. In a neutral atom, the number of electrons is equal to the number of protons, so there are 82 electrons in a neutral lead atom with an atomic number of 82.
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?
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.
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.
How many proton's neutrons and electrons of Pb are present with a mass number of 207 and an atomic number of 82?
In lead (Pb), the atomic number represents the number of protons, so there are 82 protons since the atomic number is 82. Given the mass number (207), which is the sum of protons and neutrons, subtracting the atomic number from the mass number gives the number of neutrons, which is 207 - 82 = 125 neutrons. In a neutral atom, the number of electrons is equal to the number of protons, so there are 82 electrons in a neutral lead atom with an atomic number of 82.
How many neutrons are in the atom pb?
The number of neutrons in an atom of lead (Pb) can vary depending on the isotope of lead. The most common isotope, lead-208, has 82 neutrons.
How many protons electrons and neutrons does an atom with an atomic number of 50 and mass number of 125?
An atom with an atomic number of 50 has 50 protons and 50 electrons. To find the number of neutrons, subtract the atomic number from the mass number: 125 (mass number) - 50 (atomic number) = 75 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 atom with an atomic number of 50 has 50 protons. Since the mass number is the sum of protons and neutrons, the number of neutrons can be calculated by subtracting the atomic number from the mass number. Therefore, the atom contains 50 protons, 50 electrons (since atoms are electrically neutral), and 70 neutrons (120 - 50 = 70).
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
