Although the directions say to view a PowerPoint, it is not necessary in order to complete this assignment. Six fill in the blank questions survey the periodic table of elements. A chart follows in which, given the element symbol, young...

As an atomic structure reference and review tool, this handout fits the bill. The first page provides definitions and tables of orbitals, electrons, and energy levels. The second page is an opportunity to practice determining numbers of...

Here is a top-notch handout to supply your chemistry class with. It covers valence electrons, Lewis diagrams, the octet rule, and more! Technically it is less of a worksheet than a detailed explanation of these chemical bonding concepts....

In this atom worksheet, chemists learn how to determine the number of protons, neutrons and electrons in an atom using the atomic mass and atomic number. They complete a chart of the subatomic particles and use marbles to represent...

In this electron dot structures handout, new chemists read about electron arrangement and how to draw electron dot diagrams. They complete a chart with the mass number, atomic number, isotope notation, number of neutrons, and Bohr...

After drawing the valence electron distribution of 13 basic elements, there are spaces to draw 18 more complicated molecules.  For each molecule, there is space for a Dot structure and Lewis structure that best describes the...

A short paragraph helps explain how covalent bonds are formed, and then your class will complete the Electron/Dot and Structural diagrams for the molecules given.  The valence diagrams will reinforce understanding. This activity...

In this drawing Lewis structures worksheet, students read about the 5 steps taken to draw Lewis structures for atoms and molecules. These include identifying the valence electrons, placing pairs of electrons between atoms to be bonded,...

In this electron activity, students read about how atoms lose and gain electrons and how they become ions. They are given a table with nine elements and they give the electron configuration, the number of electrons, the number of protons...

In this electron configuration and periodicity worksheet, students answer fifteen questions about periodic trends and they analyze orbital diagrams indicating location of electrons.

In this location of electrons worksheet, students read about the quantum mechanical model of the atom and the location of electrons. They complete a table given eleven elements with the sublevel notation, the Bohr notation and the...

In this electron worksheet students find values for the given letters including their subshells and in which orbital it occurs. 

Thorough explanations of the trends in the periodic table of elements make up the majority of this handout. Atomic and ionic size, ionization energy, electron affinity, and electronegativity are presented before giving chemistry...

In this periodic table worksheet, learners fill in a portion of the periodic table with the atomic number of the element, the electron configuration of the element, the number of shells and the number of outer shell electrons. They...

In this molecular shapes instructional activity, students read about how to predict molecular shapes in molecules based on the number of electron pairs and the VSEPR theory. Students are given twelve molecules, they draw the Lewis...

In this bonding worksheet, students read about the attraction of electrons to the protons in other atoms to gain, lose or share electrons in bonds. Students answer eight questions about bonding using the reading and their knowledge of...

After a short introduction, chemistry aces get right into drawing electron dot diagrams for covalent bonds. There are only three questions to answer, so this is not a comprehensive worksheet. It can be used when introducing your class to...

In this elements worksheet, students write the electron configurations for given elements. Students describe ionization energy and electron affinity and the periodic trends for both. This worksheet has 20 short answer questions.

In this chemistry activity, students complete the chart for each of the given elements by naming the number of protons, electrons, Valence electrons, and the electrons used to fill the outer shell. Then they complete each covalent bond...

In this Lewis structures learning exercise, students identify and describe what Lewis structures or dot diagrams are and how they illustrate the valence electrons in an outer shell. Then they use a periodic table to determine the numbers...

In this chemistry activity, students use the clues given at the bottom of the sheet to solve the crossword puzzle on the Periodic Table. They describe the number of protons and electrons some elements posses, as well as identify their...

For this making atoms science worksheet, students read about the atomic number of protons, finding the number of neurons, and how electrons function before they complete the atom board graphic organizer and respond to 4 short answer...

In this periodic trends worksheet, students fill out a portion of a periodic table with the atomic number, the atomic radius, the number of shells and the number of outer shell electrons for each element shown. They answer six questions...

In this chemistry, students draw the Lewis structures of 20 covalent compounds. They demonstrate how the lone pairs are distributed in the molecule.
