Across
- 3. has more electrons than protons, consequently giving it a negative charge. For an anion to form one or more electrons must be gained which is typically pulled away from other atoms that are weaker.the charge of the ion is indicated after the chemical symbol
- 5. a formula giving the number of atoms of each of the elements present in one molecule of a specific compound.
- 8. the elements on the right of the periodic table. Non-metals can be gases, liquids or solids. Non-metals are dull in color. Non-metals don't conduct electricity well because they are insulators.There is one exception it is graphite which is a non-metal which can conduct electricity.
- 9. empirical formula of a chemical compound is the simplest positive integer ratio of atoms present in a compound.
- 12. a chemical solution which is neither acidic nor basic. Neutral particle, a particle without electrical charge.
- 13. the electrostatic bond between two ions formed through the transfer of one or more electrons.
- 14. is an ion that contains more than one atom. which is different from monatomic ions, which contain only one atom.
- 15. a type of chemical element which has a preponderance of properties in between, or that are a mixture of, those of metals and nonmetals.
Down
- 1. A molecule that is composed of just one atom, and lacking any covalent bonds. The noble gases are all monatomic, when most other gases are at least diatomic
- 2. the empirical formula of any ionic or covalent network solid compound used as an independent entity for stoichiometric calculations. It is the lowest whole number ratio of ions represented in an ionic compound.
- 4. is a material that when freshly prepared or polished,shows a lustrous appearance, and conducts electricity and heat very well. Metals are typically malleable or ductile.
- 6. has more protons than electrons giving it a net positive charge. For a cation to form one or more electrons must be typically pulled away by atoms with a stronger affinity for them. the charge of the ion, is indicated after the chemical symbol
- 7. is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, when they share electrons it is known as covalent bonding.
- 10. is an electrically neutral group of two or more atoms held together by chemical bonds. Molecules are distinguished from ions by their lack of electrical charge
- 11. Ionic bonding is a type of chemical bonding that involves the electrostatic attraction between oppositely charged ions, or between two atoms with sharply different electronegativities, and is the primary interaction occurring in ionic compounds.
- 15. a type of chemical bonding that rises from the electrostatic attractive force between conduction electrons and positively charged metal ions. It may be described as the sharing of free electrons among a structure of positively charged ions
