Across
- 3. /the electrostatic bond between two ions formed through the transfer of one or more electrons.
- 6. /the temperature at which a given solid will melt.
- 8. /Any of several forces, especially the ionic bond, covalent bond, and metallic bond, by which atoms or ions are bound in a molecule or crystal.
- 12. Bond /A type of covalent bond between two atoms in which electrons are shared unequally. Because of this, one end of the molecule has a slightly negative charge and the other a slightly positive charge. See more at covalent bond.
- 13. /a process that involves rearrangement of the molecular or ionic structure of a substance, as opposed to a change in physical form or a nuclear reaction.
- 15. /relating to or denoting chemical bonds formed by the sharing of electrons between atoms.
- 18. /a usually irreversible chemical reaction involving the rearrangement of the atoms of one or more substances and a change in their chemical properties or composition, resulting in the formation of at least one new substance
- 19. /containing no permanently dipolar molecules; lacking a dipole.
Down
- 1. /an atom or molecule with a net electric charge due to the loss or gain of one or more electrons.
- 2. /a chemical process where a solid turns into a gas without going through a liquid stage.
- 4. /a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction.
- 5. /a usually reversible change in the physical properties of a substance, as size or shape
- 7. / also known as a molecular ion, is a charged chemical species composed of two or more atoms covalently bonded or of a metal complex that can be considered to be acting as a single unit.
- 9. /Binary a number assigned to an element in chemical combination that represents the number of electrons lost (or gained, if the number is negative) by an atom of that element in the compound.
- 10. /a representation of a substance using symbols for its constituent elements.
- 11. /a substance that is formed as the result of a chemical reaction.
- 14. /the temperature at which a liquid boils and turns to vapor.
- 16. /a substance that takes part in and undergoes change during a reaction.
- 17. /an ionized gas consisting of positive ions and free electrons in proportions resulting in more or less no overall electric charge, typically at low pressures (as in the upper atmosphere and in fluorescent lamps) or at very high temperatures (as in stars and nuclear fusion reactors).
- 18. /chemical compound composed of only two elements
