Question

определите число протонов и электронов в атомах изотопов;Mg 26,Pb 210,I129??срочно нужно помогите пожалуйста)

Answer 1

Mg  p=12, e=26-12=14Pb p=82, e=210-82=128  I  p=53, e=129-53=76

Answer 2

Number of Protons and Electrons in Isotopes

Here are the number of protons and electrons in the isotopes you mentioned:

1. Mg-26: The isotope magnesium-26 (Mg-26) has 12 protons and 12 electrons. [[1]] 2. Pb-210: The isotope lead-210 (Pb-210) has 82 protons and 82 electrons. [[2]] 3. I-129: The isotope iodine-129 (I-129) has 53 protons and 53 electrons. [[3]]

I hope this helps! Let me know if you have any other questions.
