Ionization energy is the energy required to remove an electron from an atom while in its stable state of being. Students review what an ion is, and how much energy would be required to remove an electron from elements based on their position in the periodic table. Sal effectively uses a graph that has ionization energy on the vertical axis, and an elements atomic number on the horizontal axis to help illustrate ionization energy.
Describing the various groups of elements within the periodic table is the focus of this video. Sal helps students understand the common characteristics that elements in the same group share. Group names include the Alkaline Metals, The Earth Metals, The Transition Metals, etc. Sal makes it clear that they are grouped together mainly because of the number of electrons they have in their outer shell.
In this periodic table worksheet, students complete a crossword puzzle given 22 clues about elements in the periodic table, periodic law, properties of elements and atomic mass and number. Students also fill in a periodic table to identify solids, liquids and gases, metals and non-metals, metalloids, and groups.
Although the article that launches this lesson is about the history of the Periodic Table, the objective is reading comprehension. Using the eight-page informational text, learners answer five comprehension questions and craft one essay. They utilize text features such as headings and graphics to more efficiently move through the questions, and mark the text as they read to note important facts. This is also a great way to teach vocabulary in context and text features. The reading is not difficult or long.
Students use the electron configurations of elements to determine their positions in the Periodic Table. For this periodic table lesson, students use the handouts provided to determine electron configurations for various elements. They use the electron configurations to organize and find elements in the Periodic Table of the Elements.
Through three separate exercises, chemistry explorers examine common atoms, the periodic table, and atomic structure. They identify the structural features of an atom, read the periodic table of elements, and calculate the atomic weight of an atom, given its atomic number. Plenty of background information is provided. The easiest way to use this resource would be to get learners online to read it and write their answers on a separate piece of paper to turn in.
Young scholars research the elements used to create fireworks. In this periodic table lesson, students discuss common metals, their characteristics, and their places on the periodic table. They work in small groups to research the elements used in fireworks and create a mural relating the elements and the fireworks.
In this trends in the periodic table worksheet, students plot the ionization energy vs. atomic number and they plot atomic radius vs. atomic number of the first 20 elements. Students analyze their graphs and answer questions about the trends in the periodic table of these elements.
One of the more comprehensive of the many periodic table applications, this one comes with a molar mass calculator, graph views, and the ability to arrange elements in the order of your choice of properties. Full of fabulous features, it is well worth the cost!
Students investigate the periodic table, the structure of the atom and the subatomic particles. In this periodic table lesson plan, students complete 5 activities in order to better understand atoms and the periodic table. They use models to represent atomic structure, they compare the mass of pennies minted before and after 1982 to represent atoms with different number of neutrons, they investigate atomic mass and they make an atom model.
High schoolers investigate the properties of elements and periodicity. In this periodicity lesson plan, students observe a bag of 'elements' which are different fruits and classify them in groups and periods, show the periodic relationships and show their similar physical and chemical properties. They use spectrum tubes and diffraction gratings to differentiate between elements, identify their atomic masses and show how the arrangement in the periodic table was determined.
Students discuss transition metals, where they are located on the periodic table, some of the element in the group, and some characteristics of the group. They work in groups to conduct an experiment in which they mix transition metals and water together to create a homemade hand warmer. Groups experience an exothermic reaction and discuss the results of their experiment.
