The Periodic Table

The Periodic Table. Jedediah Mephistophles Soltmann. Dmitri Mendeleev. Studied the properties of elements and organized the elements by similar properties (families) and by increasing atomic mass. He left blanks for elements he knew had to exist, such as:. Ekaaluminum (gallium).

Chapter 6 The Periodic Table and Periodic Law

Chapter 6 The Periodic Table and Periodic Law. The elements, which make up all living and non-living matter, fit into a orderly table. When interpreted properly, the table describes much of the elements physical and chemical properties. What is the Periodic Law and how was it formulated?.

Atomic trends

Atomic trends. Mr.Yeung. How would you find the radius of these?. Atomic Radii. The atomic radius is the distance between two nuclei when two like atoms are bonded together. In the figure above, the distance between the two nuclei in the molecule is 50 pm (1 pm = x 10 ?12 m).

Reading the Periodic Table

Reading the Periodic Table. A way of organizing & classifying elements according to their PROPERTIES. Arranged in rows and columns. Columns. The vertical (up and down) columns of the periodic table (there are 18) are called groups or families .

Periodic Trends

Periodic Trends. Reactivity of Active Metals. Active metals become more reactive as you go down a group. Ionization Energy. Energy required to remove the most loosely held electron from an atom The greater the ionization energy, the more strongly the atom holds onto its electrons

Ionization Energy

Ionization Energy. UDZ, Raji v (who has a question) Ja mes An kit. cool brain. Ionization Energy. Ionization Energy is energy required to remove an electron from the atom To separate electrons from atoms, a sufficient amount of energy is needed to overcome the attraction of nuclear charge
