the amount of energy required to remove an electron from an atom
tendency to attract an electron in a chemical bond
s and p blocks
groups 3-12 and d block
electrons on the outermost energy level of an atom
a negatively charged ion
a positively charged ion
column on the periodic table, elements with similar properties, also called a family
row on the periodic table, elements with the same valence ENERGY level
The periodic table is grouped by increasing atomic number and similar chemical/physical properties
2 atoms or ions that share the same electron configuration(same number of electrons)
increasing atomic mass

mendeleev left several holes in his first published periodic table. He felt the reason for these holes was.....
the number of principla energy is always reduced
why is the radius of a positive ion always less than the radius of its neutral atom
repulsion between electrons increases
why is the radius of a negative ion always greater than the radius o fits neutral atom?
