Which element has the atomic mass of 207.20?
Lead, with symbol Pb.
Which atomic mass is smaller cobalt or lead?
Cobalt (Co) has a smaller atomic mass than Lead (Pb). Cobalt's atomic mass is only 58.9332 while lead's is 207.2.
What element has an atomic mass of 166 with 82 protons?
An isotope of Lead, Pb.
How many grams of lead are there in 0.0275 moles of lead?
For this you need the atomic mass of Pb. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel..0015 moles Pb × (207.2 grams) = .311 grams Pb
What element is a very dense metal with an atomic mass of 207.2?
That is Lead (Pb) plumbium.
What is the lead mass?
Lead (Pb) has the atomic number 82 with an Atomic Mass of 207.2 amu.
Which element has the atomic mass of 207.20?
Lead, with symbol Pb.
Which atomic mass is smaller cobalt or lead?
Cobalt (Co) has a smaller atomic mass than Lead (Pb). Cobalt's atomic mass is only 58.9332 while lead's is 207.2.
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 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 element has an atomic mass of 166 with 82 protons?
An isotope of Lead, Pb.
How many grams of lead are there in 0.0275 moles of lead?
For this you need the atomic mass of Pb. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel..0015 moles Pb × (207.2 grams) = .311 grams Pb
What element is a very dense metal with an atomic mass of 207.2?
That is Lead (Pb) plumbium.
What element is a very dense metal with an atomic mass of 207.2 amu?
Pb, Lead
What is the mass number of this element Pb 82 207.19?
Lead is a metal element. Atomic Mass number of it is 207.
What is the mass number of this lead atom?
... that each atom of lead contains 82 protons in its nucleus.
Does cobalt or lead have a less atomic number of mass?
On the periodic table, lead (Pb) has an atomic weight of 207.2, and cobalt (Co) has an atomic weight of 58.93320.
