Ch 2-Basic Chemistry

key terms

QuestionAnswer
Isotope One of several atomic forms of an element, each with the same number of protons but a different number of neutrons, thus different in atomic mass. Ex) Carbon
Potential Energy The energy that matter possesses as a result of its location or spatial arrangement(structure)
Kinetic Energy The energy associated with the relative motion of objects. Moving matter can perform work by imparting motion to other matter.
Covalent Bond A type of strong chemical bond in which two atoms share one or more pairs of valence electrons.
Ionic Bond A chemical bond resulting from the attraction between oppositely charged ions.
Structural Formula A type of molecule notation in which the constituent atoms are joined by lines representing covalent bonds.
Molecular Formula A type of molecular notation representing the quantity of constituent atoms, but not the nature of the bonds that join them.
Nonpolar Bond A type of covalent bond in which electrons are shared equally between two atoms of similar electronegativity.
Polar Bond A covalent bond between atoms that differ in electronegativity. The shared electrons are pulled closer to the more electronegative atom, making it slightly negative and the other atom slightly positive.
Hydrogen Bond A type of weak chemical bond that is formed when the slightly positive hydrogen atom of a polar covalent bond in one molecule is attracted to the slightly negative atom of a polar covalent bond in another molecule.
Electronegativity The attraction of a given atom for the electrons of a covalent bond.

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.
