Classification of element

Back

Define proton, neutron, electron, atom, and ion.

•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.
