Across
- 2. A type of bond in which positively charged metal ions are surrounded by a "sea" of delocalized electrons.
- 4. A solid composed of ions held together by strong ionic bonds, often forming a repeating crystal lattice.
- 7. A positively charged ion formed when an atom loses one or more electrons.
- 8. Network A solid in which atoms are bonded together in a continuous network through covalent bonds, resulting in high melting points and hardness.
- 9. Electrons The electrons in the outermost energy level (shell) of an atom; they play a crucial role in chemical bonding.
- 11. Theory Valence Shell Electron Pair Repulsion theory, which predicts the three-dimensional shape of molecules based on the repulsion between electron pairs.
- 12. A group of atoms bonded together, representing the smallest unit of a compound that retains its chemical properties.
Down
- 1. Rule The tendency of atoms to gain, lose, or share electrons in order to achieve a stable electron configuration with a full valence shell of eight electrons.
- 3. A negatively charged ion formed when an atom gains one or more electrons.
- 5. A type of covalent bond in which electrons are shared equally between atoms due to similar electronegativities.
- 6. Covalent Bond: A type of covalent bond in which electrons are not shared equally between atoms due to differences in electronegativity.
- 10. A measure of an atom's ability to attract electrons in a chemical bond.
- 13. Dot Structure A representation of an atom's valence electrons using dots around the atomic symbol.
