Electronic configuration and the periodic table

what is electronic configuration

arrangement of electrons

how are electrons arranged in an atom

arranged by filling up electron shells

from inner most to outermost

max. number of electrons in one shell b4 moving to the next

Max electrons in each shell

2,8,8

what is noble gas?

elements in group 18

what are noble gas characteristics

monatomic gases ( indi atoms )

atoms have fully filled outermost shell of electrons

periodic table arrangement

column > group

row > period

what are the similarities between elements in same group

same number of electrons in outermost shell

valence electron

electrons in the outermost shell

how is position on table related to electronic structure

group number > valence electrons

period number > no. of electron shells
