experimental conditions? Your answer : a. Na+ will be maximally transported. Predict Question 2: Do you think the addition of glucose carriers will affect the transport of sodium or potassium? Your answer : a. Yes‚ it will affect the transport of both ions. Stop & Think Questions: Why did the sodium transport stop before the transport was completed? You correctly answered: c. The ATP was depleted. Why was the equilibrium for the solutes reached earlier? Your answer : a. There was more ATP available.

Electrons max. * Orbit 3 = 8 Electrons max. * Must fill inner orbits before moving to next level * The electrons in the outer most energy orbit are called valence electrons * Valance shell contains the valence electrons Ion: * An ion is simply a regular atom that is charged * It gets charged when electrons are gained or loss * During a reaction‚ atoms prefer to look like their closest Noble Gas atom in their valence shell * The ionic charge is the charge of the

not only easier to understand and unambiguous‚ but it is also usually shorter than the common way. The IUPAC system’s uses include naming binary compounds between a metal and nonmetal‚ naming binary compounds between two nonmetals‚ naming polyatomic ions‚ and naming acids and bases. To name binary compounds between a metal and a nonmetal‚ there are two different methods the IUPAC system uses. Type one is used for naming metals that form only one cation. In this method‚ the cation is named first

6 Pages 192-195 Compound • A Pure Substance composed of two or more elements in a FIXED RATIO Ionic Compound • A compound made up of one or more positive metal ions (cations) and one or more negative non-metal ions (anions) Ionic Bond • The simultaneous strong attraction of positive and negative ions in an ionic compound. As noted‚ ionic bonding occurs between metals and non-metals. Yet‚ “why and how” does this type of bonding occur? Figure 1 shows the element Neon.

conducted to work out the concentration of the chloride ions in the school swimming pool water and to see if it fits in the required range of concentration of chloride ions in the swimming pool water. This was done by titrating a small sample of the school swimming pool water with silver nitrate‚ which would form a white precipitate of silver chloride. The equation of this process is: The end point of the titration (when all of the chloride ions have been precipitated) was determined by the formation
