The Periodic Table- Metals Flashcards
Metals are found in the ______ as well as to the ____ and ______ of the periodic table.
Metals are found in the centre as well as to the left and bottom of the periodic table.
The atoms in metals are _______ packed together in _______ layers
The atoms in metals are closely packed together in regular layers
The electrons in the outer shells of metals are ____________ and are free to move throughout the ________ _______. This creates ______ metallic bonding.
The electrons in the outer shells of metals are delocalised and are free to move throughout the metallic lattice. This creates strong metallic bonding.
Most metals have ____ melting and boiling points.
Most metals have high melting and boiling points.
Metals can be bent and shaped as the ______ of atoms can _____ over each other.
Metals can be bent and shaped as the layers of atoms can slide over each other.
Alloys are ________ of a metal with other elements.
Alloys are mixtures of a metal with other elements.
Alloys are ______ than pure metals as the layers are _________ and cannot slide.
Alloys are harder than pure metals as the layers are distorted and cannot slide.
Metals are ____ conductors of electricity because the ___________ __________ move through the structure.
Metals are good conductors of electricity because the delocalised electrons move through the structure.
Metals are ____ conductors of heat as the _____________ _________ can transfer the _______ energy.
Metals are good conductors of heat as the delocalised electrons can transfer the thermal energy.
Transition metals have ______ melting points than group 1 metals and are also ________, ______ and more _____.
Transition metals have higher melting points than group 1 metals and are also stronger, harder and more dense.
Transition metals are less ________ than group 1 metals.
Transition metals are less reactive than group 1 metals.
Transition metal elements have ____ with different charges, form ________ compounds and are useful as ___________.
Transition metal elements have ions with different charges, form coloured compounds and are useful as catalysts.
metals react to form ________ ions
metals react to form positive ions
