Description

A substance that increases the hydrogen ion (H+) concentration in a solution
The attraction between different kinds of molecules
A solution in which water is the solvent.
The smallest unit of matter that retains the properties of an element.
The total mass of an atom; also called atomic weight. Given as a whole number, the atomic mass approximately equals the mass number.
The number of protons in each atom of a particular element.
A substance that decreases the hydrogen ion (H+) concentration in a solution.
A chemical substance that resists changes in pH by accepting hydrogen ions from or donating hydrogen ions to solutions.
An attraction between two atoms resulting from a sharing of outer-shell electrons or the presence of opposite charges on the atoms. The bonded atoms gain complete outer electron shells.
The sticking together of molecules of the same kind, often by hydrogen bonds.
A substance containing two or more elements in a fixed ratio. For example, table salt (NaCl) consists of one atom of the element sodium (Na) for every atom of chlorine (Cl).
A type of strong chemical bond in which two atoms share one or more pairs of valence electrons.
A type of weak chemical bond formed when the slightly positive hydrogen atom of a polar covalent bond in one molecule is attracted to the slightly negative atom of a polar covalent bond in another molecule (or in another region of the same molecule).
An atom or group of atoms that has gained or lost one or more electrons, thus acquiring a charge.
A chemical bond resulting from the attraction between oppositely charged ions.
One of several atomic forms of an element, each with the same number of protons but a different number of neutrons.
The sum of the number of protons and neutrons in an atom’s nucleus.
A type of covalent bond in which electrons are shared equally between two atoms of similar electronegativity.
A covalent bond between atoms that differ in electronegativity. The shared electrons are pulled closer to the more electronegative atom, making it slightly negative and the other atom slightly positive.
A molecule containing polar covalent bonds and having an unequal distribution of charges in different regions of the molecule.
A substance that is dissolved in a solution.
The dissolving agent of a solution. Water is the most versatile solvent known.

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.

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.
