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)
What else can I help you with?
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 If there are 128 neutrons in Pb 210 how many neutrons are found in the nucleus of Pb 206?
Lead-210 has 82 protons, so 128 - 82 = 46 neutrons in Pb-210. Lead-206 has 82 protons, so since it's a different isotope, the number of neutrons will differ. Lead-206 has 206 - 82 = 124 neutrons.
How many protons neutrons and electrons are in Pb 208?
Lead, (Pb) has an Atomic number of 82 (you can look this up on a periodic table).This means it has 82 Protons and a neutral atom also has 82 electrons.To find the number of Neutrons you subtract the Atomic Number (82) from the Atomic Mass (208).Therefore the number of Neutrons in this isotope of Lead is 208-82 = 126
How many number neutrons magnesium?
A stable magnesium atom has 12, 13 or 14 neutrons. The atom with 12 neutrons is the most common one.
How many proyons and neutrons does a oxygen atom have?
An oxygen atom typically has 8 protons and 8 neutrons in its nucleus.
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 protons are in lead Pb's atom?
Pb, Lead, has 82 protons.
How many neutrons are in an atom I?
A typical atom of iodine contains 74 neutrons.
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 in a selenium atom?
45 neutrons
What If there are 128 neutrons in Pb 210 how many neutrons are found in the nucleus of Pb 206?
Lead-210 has 82 protons, so 128 - 82 = 46 neutrons in Pb-210. Lead-206 has 82 protons, so since it's a different isotope, the number of neutrons will differ. Lead-206 has 206 - 82 = 124 neutrons.
How many protons neutrons and electrons are in Pb 208?
Lead, (Pb) has an Atomic number of 82 (you can look this up on a periodic table).This means it has 82 Protons and a neutral atom also has 82 electrons.To find the number of Neutrons you subtract the Atomic Number (82) from the Atomic Mass (208).Therefore the number of Neutrons in this isotope of Lead is 208-82 = 126
How many neutrons does a stable atom of Zn have?
A stable atom of Zinc (Zn) typically has 34 neutrons.
How do you calculate how many neutrons there are in a atom?
The atomic weight minus the number of protons = the atom's neutrons.
How many neutrons are in the center of a atom of niobium?
52 neutrons.
What is lead is made from?
Lead is an atom consisting of 82 protons and 82 electrons. The number of neutrons depends on the isotope of lead. Pb-207 isotope has 125 neutrons (207 - 82 = 125)
How many neutrons are in an atom of I?
A typical atom of iodine contains 74 neutrons.
