• Hydrogen is often given as an example of isotopes. Note that the three stable isotopes of Hydrogen are given special names. No other isotopes have special names. Protium is the only isotope that exists without any neutrons. It has one proton and one electron.
• Naturally occurring europium (Eu) consists of two isotopes with a mass of 151 g and 153 g. Europium-151 has an abundance of 48.03% and Europium-153 has an abundance of 51.97%. What is the atomic mass of europium? Show all work. 151(0.4803) + 153(0.5197) = 152.0394

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
