Study Notes
Chemical Properties of Elements
- Nitrogen and Phosphorus share similar chemical and physical properties.
- Elements found in the same group or column of the periodic table tend to have similar chemical properties.
- The more electrons an element has, the greater its electron count.
- Elements located on the left side of the periodic table tend to lose electrons, forming cations.
- Elements located on the right side of the periodic table tend to gain electrons, forming anions.
Ionic Bonding and Ion Formation
- Anions possess a negative charge.
- Alkali metals typically form ions with a +1 charge.
- Calcium forms ions with a +2 charge.
- Nitrogen forms ions with a -3 charge.
- Ionic compounds consist of a metal and a nonmetal forming a neutral compound with opposite charges.
- Compounds with a metal and a nonmetal are likely to be ionic.
Predicting Ion Charges
- Cadmium (Cd) forms +2 charged ions, reflecting its placement on the periodic table.
- Selenium (Se) is likely to have a -2 charge, aligning with its periodic table position.
- Elements within the same group on the periodic table exhibit similar charge tendencies.
Iso-Electronic Elements
- Isoelectronic ions, such as Al3+ and Ne, have the same electron configuration as Argon.
Periodic Trends and Properties
- Oxygen and Sulfur share similar chemical and physical properties, being in the same periodic group.
- Elements in the same periodic group exhibit strong similarities in both physical and chemical properties.
Identifying Anions
- The sulfide ion is represented by the chemical formula S2-.
Classifying Metal and Nonmetal Properties
- Carbon is a nonmetal, and Sodium is a metal.
- Metals lose electrons to form cations, while nonmetals gain electrons to form anions.
Ion Formation and Charge
- Chlorine forms ions with a -1 charge.
- Aluminum forms ions with a +3 charge.
Predicting Ionic Compounds
- Aluminum oxide, Al2O3, is an example of an ionic compound.
- Compounds formed between an alkali metal (like potassium) and a nonmetal are likely ionic.
Recognizing Ionic Compounds
- PCl5, a compound consisting of phosphorus (nonmetal) and chlorine (nonmetal), is not an ionic compound.
- Ionic compounds typically involve metals and nonmetals.
Formulas and Names of Ionic Compounds
- The formula for the compound formed between magnesium (Mg) and oxygen (O) is MgO.
- The correct name for CaCl2 is calcium chloride.
- The salt formed from Sr2+ and PO43- ions has the formula Sr3(PO4)2.
- The formula Fe2O3 represents iron(III) oxide.
- The correct name for Mg(NO2)2 is magnesium nitrite.
- Mg(NO3)2 is correctly named magnesium nitrate.
Recognizing Specific Compounds
- Lead (IV) oxide has the formula PbO2.
- The name SnF2 correctly describes tin (II) fluoride.

- CuSO4 is properly named copper (II) sulfate.
Predicting Compounds with Polyatomic Ions
- If calcium forms CaX with a polyatomic ion, the formula with potassium will be KX.
- The charge of the polyatomic ion is constant.
Determining Compound Ionicity
- Compounds with a greater electronegativity difference between the elements are more ionic.
- Less electronegativity difference usually results in a compound with less ionic character.
