Atom Flashcards

Physical Science Atom and Periodic table Flashcards

TermDefinition
metalliods -semiconductors-border the zigzag-1/2 complete set of electrons-propertys of metal and nonmetal-shiny but brittle-good conducter of electricity
metals -most elements-few electrons on butter energy level-solid at room temp=good conductors-shiny-malleable-right of zigzag
nonmetals -left of zigzag-have almost 1/2 complete set of electrons-1/2 are ases at room temp-property are almost opposite of metals-not shiny-poor conductors-not malleable or ductile
transition metals -metals-1 or 2 electrons in outer energy levels-less creative than Alikine earth metals-shiny and good conductors-2 vancle electrons
Alkali metals -metals-1 outter engr. level electrons-very reative-never found uncombined in nature- Most creative metal
Alaline Earth -metals- 2 electrons in outer energy levels-very creative but less creative than Alkali Metals
Halogens -nonmetals-7 electrons in outer energy levels-very reative-most creative nonmetal-never uncombined in nature-poor conductors
noble gases -nonmetal-8 (except helium it has 2) electrons outer energy levels-gases at room temp-full set of electrons-most UNreative nonmetal-electrons don't usually react with other elements
Scientists 1 Demoncritis-end up with a particle that can't be cutDalton- Mae up the atomic theory Thomas-discovered positive and negative charged particles, called protons and electrons. Made the Plums-Pudding Model
Scientists 2 Rutherford- some protons deflected the gold sheet, he found out most atoms are empty space. He discovered the nucleus. Bohr- electrons move around in certain paths or energy level. Heisnburg & Schrodinger- no exact paths, paths can't be pedicted.
Scientists 3 Heisnburg & Schrodinger- no exact paths, paths can't be pedicted. called electron clouds

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.
