Isotopes and Ions

Isotopes Atoms of the same element that have different masses Have the same number of protons and electrons but different numbers of neutrons

How many protons, neutrons, & electrons are in the following? Bromine – 80 Write the hyphen notation for the element that contains 15 electrons and 15 neutrons 13 C 6 35 p, 35 e, 45 n Phosphorus (P) – 30 6 p, 6 e, 7 n

Ions An atom or group of bonded atoms that has a positive or negative charge Positive ions have lost electrons. They have more protons than electrons. Ex: Ca 2+ Negative ions have gained electrons. They have more electrons than protons. Ex: N 3-

How many protons, neutrons, and electrons are in the following: Na + Cl - Mg 2+ O 2- Al p, 12 n, 10 e 17 p, 18 n, 18 e 12 p, 12 n, 10 e 8 p, 8 n, 10 e 13 p, 14 n, 10 e
