Quiz Which element is a good conductor, dull and brittle? Ge because it is the only a. Cu metalloid. Metalloids have b. Ge properties of metals (good conductor) and nonmetals c. Cl (dull and brittle). d. K

How do elements form a complete octet? ? Metals lose electrons to form cations – positively charged ions. Ex: Mg loses 2 electrons and becomes Mg+2 Nonmetals gain electrons to form anions – negatively charged ions. Ex: Cl gains 1 electron and becomes Cl-1 What are the charges of the following groups: 1. Alkali metals 2. Alkaline Earth metals 3. Halogens

Quiz How does sulfur (S) obtain a complete octet? a. Gain 1 electron b. Gain 2 electrons c. Lose 6 electrons S has 6 valence e- so it gains 2 more to make 8. d. Lose 2 electrons

Quiz How does sodium (Na) obtain a complete octet? a. Lose 1 electron b. Lose 2 electrons c. Gain 1 electrons. Na has 1 valence e- so it loses it to make a d. Gain 2 electronscomplete octet.

Quiz What is the charge of bromide (Br)? a. -1 b. -2 c. -17 d. +1

Quiz What is the charge of aluminum (Al)? a. +1 +3 because it loses 3 b. +2 valence ec. +3 d. +4

Quiz Which of the following elements will form a cation? a. Sr b. N c. I d. Ne

Anions are negative because they… Quiz a. Lose electrons. b. Gain electrons. These are all negative.

How do transition metals form a complete octet? ? Transition metals, tin and lead lose electrons to form cations. However, they lose a varying amount of electrons so Roman Numerals must be used to indicate how many electrons were lost. Ex: Copper may lose 1 electron and become Cu+1 or copper may lose 2 electrons and become Cu+2.

Quiz What is the name of Fe+2? a. Iron b. Iron ion The Roman c. Iron (II) ion numeral indicates the charge d. Iron (I) ion

Atomic Radius Atoms become smaller across a period. Atoms become larger down a group.

Quiz Which element is larger? a. K b. Br

Quiz Which element is larger? a. F b. Br

Electronegativity Elements on the top right side attract electrons within chemical bonds. Notice fluorine (F) has the highest value. It strongly attracts electrons. Do Not attract e-. They give theirs away.

Quiz Which element will more strongly attract electrons? a. Sr b. I

Ionization Energy Ionization energy increases across a period. In other words, it is more difficult to remove electrons from elements with higher group numbers. Ionization energy decreases down a group. In other words, it is easier to remove electrons from larger atoms. Lose eeasily – does not take much energy to remove e- Do not lose e- easily 0 – takes lots of energy to remove e-
