| Answer | Question |
|---|---|
| invovles the sharing or transfer of electrons to attain stable electron configurations for the bonding atoms | What is a chemical Bond? |
| the number of protons an atom posses controls the size of the positive charge in the nucleus | What is attractive force |
| electrons exert a force on one another | What is the force of repulsion |
| down a column | Atomic raduis increases with |
| from left to right | atomic radius decreases |
| Group 1A and VII are opposite | affect on chemical reactivity |
| the electons transferred | What happens during an Ionic Bond |
| When the electrons are shared | What happens during a covelant Bond |
| When two electrons paris are shared between two atoms | What is a double Bond |
| Are shorter and stronger than double bonds | What is a Triple Bond |
| the product of different types of valence electron interaction | What are chemical Bonds between atoms and ions |
| ionic species with a positive charge. | what is a cation |
| atom or group of atoms carrying a negative charge. The charge results because there are more electrons than protons in the anion. | what is an anion |
| set of quantum numbers associated with the energy states of the atom | what is the principle quantum number |
| Within each energy level there are n subshells, described by the azimuthal quantum number l. l can have a value from 0 to (n-1). The value of l determines the shape of the subshell that the atom is in. | what are the subshells |
| Describe the probable location of an electron | what are quantum numbers |
| hat atoms tend to gain, lose or share electrons so as to have eight electrons in their outer electron shell. | What is the octlet Rule |
| every orbital in a subshell is singly occupied with one electron before any one orbital is doubly occupied, and all electrons in singly occupied orbitals have the same spin | What is the Hunds Rule |
| forces that act between stable molecules or between functional groups of macromolecules. | What is intermolecular force of Attraction |
| as you move across a period or row to the right | Ionic Energy Increases |
| As you move down a column | Ionic Energy Decreases |
| As you move across a period or a row to the right | Metallic Charecter Decreases |
| As you move down a collumn or a family | Metallic Charecter Increases |
| Involve the shareing of Single pair of electrons | Single Bonds |
| Involve the sharing of two pair of electrons | Double Bonds |
| Involve the sharing of three pair of electrons | Triple Bonds |
| the measure of the ability of an atom within a molecule to attract bonding electrons | Electrongativity |
| Rapidly as you move up the periodic table | Electronegrativity increases |
| slowly as you move from left to right across a row | Electronegativity generally Decreases |
| where the bonding electron pair has a higher probability of being found near one atom than the other | polar covelant bonds are |
