What is the hyphen notation for an atom with 82 protons, 125 neutrons and 82 electrons?<\/p>\n\n\n\n

The Correct Answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n

The hyphen notation for an atom with 82 protons, 125 neutrons, and 82 electrons is Lead-207<\/strong> (Pb-207).<\/p>\n\n\n\n

Explanation:<\/h3>\n\n\n\n

The hyphen notation is a way of representing an isotope of an element. It is written as the element symbol, followed by a hyphen, and the mass number of the isotope. The mass number is the sum of protons and neutrons in the nucleus of an atom.<\/p>\n\n\n\n

Step-by-step breakdown:<\/h4>\n\n\n\n
    \n
  1. Protons<\/strong>: The number of protons in an atom determines the element. In this case, the atom has 82 protons<\/strong>, which corresponds to lead (Pb)<\/strong> on the periodic table. The atomic number of lead is 82, meaning that all atoms with 82 protons are lead atoms.<\/li>\n\n\n\n
  2. Neutrons<\/strong>: The number of neutrons is not fixed for an element; different isotopes of the same element can have different numbers of neutrons. This particular atom has 125 neutrons<\/strong>.<\/li>\n\n\n\n
  3. Mass Number<\/strong>: The mass number is the total of protons and neutrons. For this atom, the mass number is calculated as: [
    \\text{Mass number} = \\text{Protons} + \\text{Neutrons} = 82 + 125 = 207
    ] So, the mass number is 207<\/strong>.<\/li>\n\n\n\n
  4. Electrons<\/strong>: Since the atom is neutral (it has an equal number of protons and electrons), the number of electrons is also 82<\/strong>. The number of electrons is not needed for the hyphen notation, as the notation focuses on the atomic composition (protons and neutrons).<\/li>\n<\/ol>\n\n\n\n

    Conclusion:<\/h3>\n\n\n\n

    The atom is a lead isotope<\/strong> with 82 protons and 125 neutrons, and its hyphen notation is Pb-207<\/strong>, where “Pb” is the symbol for lead and “207” is the mass number. This isotope is known as Lead-207<\/strong>, and it is stable and naturally occurring in trace amounts in the Earth’s crust.<\/p>\n","protected":false},"excerpt":{"rendered":"
