MLO1-7 Evaluate an isotope to determine the atomic number, mass number, the number of electrons, protons or neutrons and charge.
MLO1-8 Identify the forms of radiation and balance nuclear reactions in which these particles are emitted or absorbed
MLO1-9 Describe isotopes and calculate the average atomic mass of an element given the atomic mass and relative abundance each of its naturally occurring isotopes.
MLO1-10 Convert between mass, moles and number of atoms using the relationships between Avogadro’s number, moles, molar mass and grams.
MLO1-11 Identify the symbols and names of common elements on the periodic table.
MLO1-12 Explain the organization of the Periodic Table of Elements in terms of families, groups, periods, metals, semimetals and nonmetals

Tyler DeWitt - Learn how to write atoms in isotope notation! In isotope notation, you can quickly show how many protons, neutrons, and electrons are in an atom. You put the atomic number, mass number, and net charge around the chemical element symbol. Isotope notation is particularly important in nuclear chemistry, because if you're doing fission, fusion, alpha decay, beta decay, positron emission, or electron capture, you want to be able to tell how many neutrons and protons are in the nucleus.

Description
Description
Build an atom out of protons, neutrons, and electrons, and see how the element, charge, and mass change. Then play a game to test your ideas!
Sample Learning Goals
Sample Learning Goals
Use the number of protons, neutrons, and electrons to draw a model of the atom, identify the element, and determine the mass and charge.
Predict how addition or subtraction of a proton, neutron, or electron will change the element, the charge, and the mass.
Use the element name, mass, and charge to determine the number of protons, neutrons, and electrons.
Define proton, neutron, electron, atom, and ion.
Generate an isotopic symbol for an atom, given the number of protons, neutrons, and electrons.

Tyler DeWitt - What is atomic mass? It is a weighed average of the different isotopes of an element. It is sometimes referred to as atomic weight, relative atomic mass, or average atomic mass. We look at how to calculate and determine the weighed average of elements using atomic mass units.
