reactivity series Flashcards
what are the physical properties
- malleable
*ductile
*High melting and boiling point - High density
- good conductor of heat
- good conductor of electricity
*lustrous (shiny)
what is the meaning of malleable
malleable is to form different shapes
what is ductile
can be pulled into long wires
what is the arrangements of atoms is pure metals
the atoms in metals are packed together very closely , there is little empty space for atoms
and
when a force is applied, the layers of atoms in a metal can slide over each other easily
why do atoms in pure metal contain high density
the atoms in metals are packed together very closely , there is little empty space for atoms
why are atoms in pure metals are malleable and ductile
when a force is applied, the layers of atoms in a metal can slide over each other easily
what is the definition of alloys
alloys are a mixture of one or a few other metallic or non-metallic elements
what are pure metals
compromises of identical atoms of the same element, atoms have the same size
how are pure metals arranged
atoms are in ordinary and regular arrangements
what happens if a force is applied to pure metals
if a force is applied, layers of atoms, slide over each other easily
what are the properties of a pure metal
pure metals can be bent or beaten can be bent or beaten into shapes
what is the arrangement of alloy atoms
alloy atom are in disorderly & irregular arrangement
what happens if force is applied to an alloy
when a force is applied on to an alloy, layers of atom wont slide over each other easily
what happens if you try to bend an alloy
alloys cant be bent as they are harder and more difficult to bend than pure metals
what example of alloys
brass
stainless steel
pewter
solder
