Introduction to Metals N5 Lesson 1

When metals form ions, they ...

• lose electrons and become positively charged

• lose electrons and become negatively charged

• gain electrons and become positively charged

• gain electrons and become negatively charged

Metals are found

• below the dark line of the periodic table

• above the dark line of the periodic table

• in group 1, 2 and the transition metal area only

• both above and below the dark line of the periodic table

Which of these is NOT a property of metals?

• Ductile

• Strong

• Conductor of Electricity

• Insulator of Heat

Metals are held together by

• ionic bonds

• covalent bonds

• intermolecular bonds

• metallic bonds

A metallic bond is

• electrostatic attraction between positive and negative ions

• electrostatic attraction between negative ions and positively charged charged delocalised electrons

• electrostatic attraction between positive ions and negatively charged delocalised electrons

• shared pair of electrons between 2 positive nuclei

Because metals are held together by strong metallic bonds they ...

• conduct electricity

• do not conduct electricity

• have high melting and boiling points

• have high melting points but low boiling points

Metals conduct electricity because

• they have free moving (delocalised) electrons that can carry current)

• the crystal lattice is broken and the ions are free to move

• because they are held together by strong metallic bonds

• they are shiny
