Front (Question)

What is the structure of metallic bonding?

Back (Answer)

• lattice of positive metal ions • sea of delocalised electrons

Front (Question)

Define metallic bonding

Back (Answer)

electrostatic attraction between positive metal ions and negative delocalised electrons

Front (Question)

Why do metals have high melting points?

Back (Answer)

• metallic bonding is very strong • lots of energy needed to break

Front (Question)

How are metals able to conduct electricity?

Back (Answer)

• delocalized electrons are free to move

Front (Question)

Why are metals so malleable?

Back (Answer)

• layers of metal ions that can slide over each other

Front (Question)

What are the properties of metals?

Back (Answer)

high melting points malleable conduct electricity

Front (Question)

What is thermal decomposition?

Back (Answer)

heat energy used to break down a substance

Front (Question)

What is metal carbonate decomposition?

Back (Answer)

when metal carbonate thermally decomposes to form - metal oxide - carbon dioxide

Front (Question)

What does metal carbonate decomposition form?

Back (Answer)

metal oxide carbon dioxide

#10

Front (Question)

What is downward delivery?

Back (Answer)

carbon dioxide sinks to the bottom of tube and remains there bc it is denser than air

#19

Front (Question)

What are the observations of metal + water reactions?

Back (Answer)

effervescence solid disappears

#20

Front (Question)

Why does effervescence occur in metal + water reactions?

Back (Answer)

hydrogen gas produced

#21

Front (Question)

Why does the solid disappear in metal + water reactions?

Back (Answer)

used up in the reaction

#22

Front (Question)

What forms when the metal + water reaction has happened?

Back (Answer)

an alkali hydroxide is donated to water

#23

Front (Question)

What is different when Group 1 metals react with water?

Back (Answer)

very violent

Back (Answer)

solid floats effervescence solid moves solid disappears
