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
which one dissociates ionic or covalent compound?
ionic
which is hydrophilic and hydrophobic covalent or ionic
ionic- hydrophilic
covalent- hydrophobic
which type of compound melts easily ionic or covalent
ionic- do not melt easily
covalent- melt easily
which type of compound is brittle ionic or covalent
ionic
which type of compound conducts electricity when dissolved in water ionic or covalent?
ionic
