periodic table and trends Flashcards
what are the properties of metals?
shiny dense high melting points Ductile and malleable Good conductors or electricity
what are the properties of non metals?
dull
Low melting points
Brittle
Poor conductors of electricity
what are the properties of metalloids?
Shiny or dull
Electricity and heat can travel through them (semi conductor)
when are electrons most happy?
when valence shell is full

top right
when is the atomic radius the biggest?
bottom left
what is ionization energy?
the amount of energy required to remove an electron .
what is electron affinity
the amount of energy released when an electron is attached to a neutral atom or molecule
what is the formula that shows the relationship between force, electric charge, and distance.
force = charge/distance^2
what is Electronegativity?
the ability to attract/steal electrons
where on the periodic table is electronegativity the strongest?
right
what are the properties of oxides?
chemical compound that contains at least one oxygen atom and one other element in its chemical formula
what are the 3 types of bonding?
ionic, covalent, and metallic
