... that each atom of lead contains 82 protons in its nucleus.
the atomic number of lead is 82 and the symbol is Pb
Lead is a metal element. Mass number of it is 207.
The atomic # is 82, symbol Pb.
207.2 a.m.u.
the mass number is number of protons in an atom, plus the number of neutrons.
mass no - atomic no = number of neutrons in an atom.
It has 8 protons. The atomic number of an atom = the number of protons. The mass number is not needed in this problem. The mass number is the number of protons + number of neutrons.
the mass number of an atom is used to calculate the number of neutrons and protons in the nucleus of an atom
NEUTRONS AND PROTONS are counted in an atom to determine it's mass number.

The lead atom is way heavier than the helium atom. We know this by referring to the Periodic Table of Elements. The atomic mass of lead (Pb) is 207, while that of helium (He) is 4. Therefore, we can estimate that an atom of lead is about 50 times heavier than an atom of helium.
Yes, because each hydrogen atom has less mass than each lead atom.Yes, because each hydrogen atom has less mass than each lead atom.Yes, because each hydrogen atom has less mass than each lead atom.Yes, because each hydrogen atom has less mass than each lead atom.
the mass number is number of protons in an atom, plus the number of neutrons.
You can't change the mass number of an atom because the mass number is the number of protons which is the atom's atomic number I hope this helped :)
The number of neutrons in an atom can affect the atomic mass of an atom.
Atomic number is the number of protons in the atom; atom mass is the total mass of the atom (usually neglecting the mass of the electrons because they have so little).
Lead is a non element. Atomic mass of it is 12.
The mass number tells us the number (the sum) of protons and neutrons in the nucleus of an atom.
mass no - atomic no = number of neutrons in an atom.
atomic mass is the number of protons in an atom mass number is the number of protons plus neutrons in an atom
The mass number of an atom is equal to the sum of its number of protons and neutrons, simply, nucleons.
