Chapt. 5-3

Difficult to determine size: small, energy level changes two identical chem. bonded and then / number of protons affecting valence Atomic Radii
Atomic Radii decreases to the right due to increased positive charge in nucleus, pulls in Period Trends
Radius increases as you move down GA smaller due to force moving horizontally Group trends
Electrons can be removed froma n atoms if enough energy is supplied (kicking) A+ energy---> A+ + E A+= ion of elements with a positive charge A+ energy---> Ionization
Element with a single positive charge Ion
energy required to remove an electron from it's neutral state Measurements made in gas phase Larger atomic # = less energy Noble gas config= LOTS Of energy D and f block increase across a period, increase down a group Ionization Energy
Energy change that occurs when an electron is acquired by a neutral atom Most atoms release energy when acquiring, others must be forced to gain by using energy Electron affinity
Adding a second electron to a negative ion is difficult All second electron affinities are positive Adding electrons to negative ions
positive ion decrease of electrons smaller cloud, pulled in cation
negative Ion addition of electrons larger cloud, less pull anion
electrons available to be lost, gained, or shared when forming chemicals compounds determines properties Group #-10 for the number of valence electrons Valence electrons
Measure the ability of an atoms in a chem. compound to attract electrons form another compound atom In relation to F Number below on table Not common because of partially filled s-sublevels Electronegativity
Radii decreases along f-block period F-block properties

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.
