Who is the founder of current periodic table system?
Dmitri Mendeleev
Antonie Lavoisier

Which element has the highest electronegativity?
Metallic character is based on...
how shiny something is.
the density of a material.
an atom's ability to lose electrons.
the ability to conduct electricity.
This results in decreased attraction of electrons for the nucleus of an atom due to inner electrons blocking the attraction of valence electrons.
