Chapter Three

Chapter Three

0. Chapter Three. Atoms and the Periodic Table. 0. Atomic Theory. All matter is composed of atoms Atoms of each element are unique Atoms are composed of subatomic particles (protons, neutrons and electrons) Atoms combine to form compounds in definite proportions

ELEMENT CLASSES

ELEMENT CLASSES

ELEMENT CLASSES. CA Standards. Students know how to use the periodic table to identify alkali metals, alkaline earth metals, transition metals, metals , semimetals (metalloids), nonmetals, halogens and noble gases. Alkali Metals. All alkali metals have 1 valence electron

Nonmetals, Nobel Gases, and Metalloids

Nonmetals, Nobel Gases, and Metalloids

Nonmetals, Nobel Gases, and Metalloids. Life on Earth depends on certain nonmetal elements. The air you and other animals breathe contains several nonmetals, including oxygen. And all living organisms are made from compounds of the nonmetal carbon.

Ionization Energy

Ionization Energy

Ionization Energy. What is “ionization energy”? Answer: the energy required to remove an electron from a gaseous atom This means that energy is required to form positive ions. Energy is released when a negative ion is formed. . Ionization Energy (continued). Examples:

Periodic Trends

Periodic Trends

Periodic Trends. OBJECTIVES: Interpret group trends in atomic radii, ionic radii, ionization energies, m.p., b.p., electronegativity and chemical properties. Trends in Atomic Size. First problem: Where do you start measuring from? The electron cloud doesn’t have a definite edge.

Elements are arranged:

Elements are arranged:

Vertically into Groups. Horizontally Into Periods. Elements are arranged:. Why?. If you looked at one atom of every element in a group you would see…. Each atom has the same number of electrons in it’s outermost shell. An example….
