Across
- 3. Table – A tabular arrangement of elements, organized by increasing atomic number and grouped by similar properties.
- 5. – A process that uses rapid spinning to separate components of a mixture based on their density.
- 10. – Atoms of the same element with the same number of protons but different numbers of neutrons.
- 11. – The outermost electrons in an atom that are involved in forming bonds.
- 13. – The smallest unit of an element, consisting of a nucleus and one or more electrons.
- 14. – A separation process that involves boiling a liquid to create vapor and then condensing the vapor back into liquid to separate components based on boiling points.
Down
- 1. – A technique used to separate solids from liquids or gases using a filter that allows only the fluid to pass through.
- 2. – A region in an atom where there is a high probability of finding electrons.
- 4. Configuration – The arrangement of electrons in the orbitals of an atom.
- 6. Number – The number of protons in the nucleus of an atom, which defines the element and its position in the periodic table.
- 7. – A technique used to separate a substance from a mixture by dissolving it into a solvent. **Sublimation** – A process where a solid changes directly into a gas without passing through the liquid phase.
- 8. – The process of adding or removing electrons from an atom or molecule to create ions.
- 9. Number – The number of neutrons in an atom’s nucleus, which, along with the proton number, determines the isotope of the element.
- 12. – A technique used to separate mixtures into their individual components based on differences in their movement through a medium.
