Description

angles made by the lines joining the nuclei of the atoms in the molecule
a region where electrons are found; negatively charged and therefore repel one another; the best arrangement of a given number of electron domains is the one that minimizes the repulsions among them
electrons that defines a region in which the electrons are most likely to be found
defines an electron domain that is located principally on one atom
the arrangement of electron domains about the central atom or ion
the arrangement of only the atoms in a molecule or ion
the dipole moment due to the two atoms of a covalent bond.
a model of chemical bonding in which an electron-pair bond is formed between two atoms by the overlap of orbitals on the two atoms.
the extent to which atomic orbitals on different atoms share the same region of space. When the overlap between two orbitals is large, a stong bond may be formed.
orbitals that result from the micing of different kinds of atomic orbitals on the same atom. For example, an sp^3 hybrid results from the mixing. or hybridizing, of one s orbital and three p orbitals.
the mixing of different types of atomic orbitals to produce a set of equivalent hybrid orbitals.
a covalent bond in which electron density is concentrated along the internuclear axis.
a covalent bond in which electron density is concentrated above and below the line joining the bonded atoms.
electrons that are spread over a number od atoms in a molecule rather than localized between a pair or atoms
a theory that accounts for the allowed states for electrons in molecules.
an allowed state for an electron in a molecule.
a molecular orbital that centers the electron density about an imaginary line passing through two nuclei.
a diagram that shows the energies of molecular orbitals relative to the atomic orbitals from which they are derived. Also called molecular orbital diagram.
the number of bonding electron pairs shared between two atoms, less the number of antibonding electron pairs.
a molecular orbital that concentrates the electron density on opposite sides of a line that passes through the nuclei.
a property that a substance possesses if it contains one or more unpaired electrons. a paramagnetic substance is drawn into a magnetic field.
a type of magnetism that causes a substance with no unpaired electrons to be weakly repelled from a magnetic field.

Frequently Asked Questions

What is a crossword?

Crossword puzzles have been published in newspapers and other publications since 1873. They consist of a grid of squares where the player aims to write words both horizontally and vertically.

Next to the crossword will be a series of questions or clues, which relate to the various rows or lines of boxes in the crossword. The player reads the question or clue, and tries to find a word that answers the question in the same amount of letters as there are boxes in the related crossword row or line.

Some of the words will share letters, so will need to match up with each other. The words can vary in length and complexity, as can the clues.

Who is a crossword suitable for?

The fantastic thing about crosswords is, they are completely flexible for whatever age or reading level you need. You can use many words to create a complex crossword for adults, or just a couple of words for younger children.

Crosswords can use any word you like, big or small, so there are literally countless combinations that you can create for templates. It is easy to customise the template to the age or learning level of your students.

How do I choose the clues for my crossword?

Once you’ve picked a theme, choose clues that match your students current difficulty level. For younger children, this may be as simple as a question of “What color is the sky?” with an answer of “blue”.

Are crosswords good for students?

Crosswords are a great exercise for students' problem solving and cognitive abilities. Not only do they need to solve a clue and think of the correct answer, but they also have to consider all of the other words in the crossword to make sure the words fit together.

Crosswords are great for building and using vocabulary.

If this is your first time using a crossword with your students, you could create a crossword FAQ template for them to give them the basic instructions.

Can I print my crossword template?

All of our templates can be exported into Microsoft Word to easily print, or you can save your work as a PDF to print for the entire class. Your puzzles get saved into your account for easy access and printing in the future, so you don’t need to worry about saving them at work or at home!

Can I create crosswords in other languages?

Crosswords are a fantastic resource for students learning a foreign language as they test their reading, comprehension and writing all at the same time. When learning a new language, this type of test using multiple different skills is great to solidify students' learning.

We have full support for crossword templates in languages such as Spanish, French and Japanese with diacritics including over 100,000 images, so you can create an entire crossword in your target language including all of the titles, and clues.
