What is an atom?
100
Atoms of the same element that have different numbers of neutrons
What is an isotope?
100
A table that shows the elements, their atomic number, symbol, and average atomic mass; elements with similar chemical properties are grouped together.
What is the periodic table?
100
Elements that are good conductors of heat and electric current.
What is a metal?
100
Elements that are poor conductors of heat and electric current. Most are gases, dull & brittle
What is a non-metal?
200
Proton Neutron Electron
