QuestionAnswer
Mis tüüpi side tekib, kui aatomid jagavad elektrone? Kovalentne side
Mis tüüpi side tekib, kui üks aatom annab elektroni teisele? Iooniline side
Mis tüüpi side on metallides? Metalliline side
Mis on molekulaarne aine? Aine, mis koosneb molekulidest
Mis hoiab molekule koos molekulaarses aines? Nõrgad molekulidevahelised jõud
Millised on molekulaarsete ainete omadused sulamistemperatuuri ja keemistemperatuuri järgi? Madalad sulamis- ja keemistemperatuurid
Too näide gaasilisest molekulaarsest ainest. Näiteks O₂, HCl, CH₄
Too näide vedelast molekulaarsest ainest. Näiteks Br₂, etanool (C₂H₅OH)
Too näide tahkest molekulaarsest ainest. Näiteks jood (I₂), väävel (S₈), suhkur
Miks on jood (I₂) tahke, aga kloor (Cl₂) gaas? Joodi molekulid on suuremad, nendevahelised jõud tugevamad
Mis on mittemolekulaarne aine? Aine, mis koosneb aatomitest või ioonidest, mitte molekulidest
Milline kristallvõre on ioonsetel ainetel? Ioonvõre
Too näide ioonsest ainest. NaCl (naatriumkloriid)
Mis tüüpi kristallvõre on metallidel? Metallvõre
Mis on aatomvõre? Võre, mille sõlmpunktides on aatomid, mis on seotud kovalentsete sidemetega
Too näide ainest, millel on aatomvõre. Näiteks teemant, räni, kvarts (SiO₂)
Miks on teemant väga kõva? Sest kõik aatomid on seotud tugeva kovalentse sidemega kolmemõõtmelises võres
Miks on grafiit pehme? Kihtide vahel on vaid nõrgad jõud, seetõttu kihid libisevad kergesti
Mis ühend seob räniaatomeid kvartsis? Hapniku aatomid
Kuidas erinevad molekulaarsed ja mittemolekulaarsed ained elektrijuhtivuse poolest? Molekulaarsed ained tavaliselt ei juhi elektrit, mittemolekulaarsed (nt metallid, ioonained) juhivad

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.
