A mutual electrical attraction between the nuclei and valence electrons of different atoms that binds the atoms together is called a(n) From here, you can test yourself to see if you know the trends in the periodic table or you might wish to review the types of chemical bonds. If you're ready for another quiz, find out which type of mad scientist you are or you can practice naming ionic compounds . The only way to learn this stuff is to practice. But how you practice matters. First, understand why Lewis structures, molecular shape, and polarity are important – that will enhance your ability to learn. Try the problems first, struggle a bit, and then look at the answers. Struggling means you're learning. Make sure you have the basics.

Shapes of Molecules The shape of a molecule depends on the number of pairs of electrons in the outer most shell surrounding a central atom. Once you find out how many bonding pairs and non-bonding pairs there are the rest is easy molecules must have a different shape. 6. Make a molecule which contains both 90o bond angles and 120o bond angles. 7. Make TWO linear molecules. One with 2 e- domains and one with 5 e- domains. 8. Make the most “stable” molecule of SeCl4.

Construct another of SeCl4 that is not “stable”. (In other words, a different isomer.) 9. The Shape of Molecules. The three dimensional shape or configuration of a molecule is an important characteristic. This shape is dependent on the preferred spatial orientation of covalent bonds to atoms having two or more bonding partners. Three dimensional configurations are best viewed with the aid of models. 2: State and explain the shape of the ammonia molecule, NH 3. 3: Compare the shapes of the H 2 O molecule and the H 3 O + ion, and use this to explain why the bond angle in H 2 O is 104.5º while the bond angle in H 3 O + is 107º. 4: Draw the 3D shape of the following molecules. i) chloromethane, CH 3 Cl. ii) phosphine, PH 3

The consequences of this is that it becomes easy to move individual molecules away from other molecules as the bonding between molecule is weak, hence, it needs little energy to break. Since, temperature is proportional to energy, which means the temperature required to melt the compound is low.
