The periodic law states that
no two electrons with the same spin can be found in the same place in an atom.
the physical and chemical properties of the elements are functions of their atomic numbers.
electrons exhibit properties of both particles and waves.
the chemical properties of elements can be grouped according to periodicity but physical properties cannot.
Mendeleev predicted that the spaces in his periodic table represented
permanent gaps.
undiscovered elements.
radioactive elements.
isotopes.
What characteristic do atoms in the same group of elements share?
They have the same atomic mass.

lose an electron
gain an electron
Choose more than one: Which of these are non metals
dull
conductive
Non conductive
lose an electron
gain an electron
Choose more than one: Which of these are metalloids
dull
shiny

lose an electron
gain an electron
Why do the halogens become more reactive as you go up whereas metal become more reactive as you go down?
Electron shielding remove electrons and halogens want to gain electrons
Atomic radius increase and cause the electrons to be gained
Electronegativity is higher for the metals than the nonmetals
What goes up must come down
Nuclear charge is caused by
the attraction of the electron to the neutrons
the attraction of the electron to the nucleus
the attraction of the protons to the nucleus
