Identify any isotopes of the same element: • there are two magnesium atoms in the chart – one has 13 neutrons and one had 12 neutrons so these atoms are isotopes of each other 24. Explain why many of the atoms and ions in the chart above have the same number of electrons, but they have different total electric charges.
Atomic Structure Answer Key . Use a periodic table to help you fill in the chart below. Mass numbers are rounded to the nearest whole number. Remember: Atomic number = number of protons = number of electrons Mass number = number of protons + number of neutrons Element Symbol Atomic Number Mass Number Number of Protons Number of Neutrons Number of
