Metals & Non-Metals

Properties of metals

TermDefinition
Physical Properties of Metals strong, malleable, ductile, sonorous, shiny, good conductors of heat & electricity, high mpts and bpts, high density
Why are metals strong? atomic density=stable and close together
Why are metals malleable? layers of metal atoms can be shifted without breaking metallic bonds
Why are metals ductile? layers of metal atoms can be shifted as well
Why are metals sonorous? delocalized electrons sending waves of kinetic energy, little energy lost
Why are metals shiny? vibrating delocalized electrons contact with light
Why are metals good conductors of heat & electricity delocalized electrons able to carry the energy and the flow of charge
Why do metals have mpts and bpts? strong metallic bonds
Why do metals have high density? strong metallic bonds with ‘sea’ of delocalized electrons, closely packed
Chemical Properties of Metals react with oxygen to form oxides (which are bases) which then form salts and water when reacting with acids & when they react, they form positive ions

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
