What is the sum of protons and neutrons in an atom?
Mass number!:)
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)
What does the number of neutrons determine?
The number of neutrons in an atom determines the isotope of the element. Isotopes of an element have the same number of protons but differing numbers of neutrons. This affects the stability and nuclear properties of the atom.
What is the mass number of 10 protons and 10 neutrons?
20. the mass of an atom is determined by the sum of the number of neutrons and protons the atom has.
The mass number of an atom indicates the number of what?
The mass number is the sum of protons + neutrons.
What is the mass number of an lead atom that has 80 neutrons?
The mass number of an atom is equal to the sum of the number of protons and neutrons in its nucleus. Since lead has an atomic number of 82 (number of protons), if the lead atom has 80 neutrons, then the mass number would be 82 (protons) + 80 (neutrons) = 162.
How many neutrons are in a normal number of led?
Lead has 125 Neutrons in each normal atom that is not an isotope.
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.
What is the mass number of lead that has 127 neutrons?
The mass number of an atom is the sum of its protons and neutrons. Lead (Pb) has an atomic number of 82, so it has 82 protons. If it has 127 neutrons, the mass number would be 82 (protons) + 127 (neutrons) = 209.
How many neutrons are in one atom?
The number of neutrons in one atom can vary depending on the element. Neutrons are one of the three main subatomic particles found in an atom, along with protons and electrons. The number of neutrons in an atom is calculated by subtracting the number of protons (atomic number) from the atomic mass of the atom.
What is the number of neutrons in an atom affects the atomic what?
The number of neutrons in an atom can affect the atomic mass of an atom.
What is the sum of protons and neutrons in an atom?
Mass number!:)
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 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)
What is the number of neutrons in an atom called?
The number of neutrons in an atom is called the neutron number.
What does the number of neutrons determine?
The number of neutrons in an atom determines the isotope of the element. Isotopes of an element have the same number of protons but differing numbers of neutrons. This affects the stability and nuclear properties of the atom.
What is the total amount of protons and neutrons in an atom?
The total amount of protons and neutrons in an atom is its mass number.
