LEWIS DOT SYMBOL Flashcards
electrons located at the outermost ( highest principal energy level
valence electrons
electrons located between the valence electrons and the nucleus
core electrons
designates the valence electrons
-by Gilbert lewis
lewis dot diagram
what is the maximum no. of valence electrons
8
what sub shells corresponds to the valence electrons?
the ones with the highest whole number
what group has a complete number of valence electrons
noble gasses
why do elements form a chemical bond?
to become stable and unreactive and to complete the 8 valence electrons
when two reactive elements combine to complete your valence electrons, force that holds two or more atoms together
chemical bonding
product of a chemical bonding?
compound
two types of ions:
cation (positive)
anion (negative)
what are the types of bonding
Ionic bonding
- metal + non meta
electrolyte
-dissociates
conductive
Covalent bonding
- nm + nm
- non-electrolyte
- non-conductive
metallic bondig
- m + m
electrolyte
-conductive
visualize the periodic table that is classified as non metals, metals, metalloid
what are the requirements of a substance or mixture to conduct electricity
- must contain charged particles
-charged particles must be free to migrate or move
type of bond due to the attractive electrons force between cations (+metals) and anions (-nonmetals)
ionic bond
type of bond due to the sharing of electrons of two or more nonmetal atoms
covalent bond
