Group 18/ 8A elements | Noble gases |
first periodic table arranged elements by ____________ | increasing atomic mass |
Shatters when hammered | brittle |
number of protons | atomic number |
current periodic table arranges elements by _________ | increasing atomic number |
change in number of electrons | ion |
change in number of protons | a different element |
