Chemistry Bonding
Across
- 2. structures/ formulas in which atomic symbols represent nuclei and inner-shell electrons, dot-pairs or dashes between two atomic symbols represent electron paris in covalent bonds, and dots adjacent to only one atomic symbol represent unshared electrons
- 3. covalent bond/ a bond formed by sharing three pairs of electrons
- 5. bonding/ the chemical bonding that results from the attraction between metal atoms and the surrounding sea of electrons
- 6. numbers/ Shows how many electrons can be shared, lost or gained to become stable; you cancel out the valence numbers to make the compound
- 7. ions/ They consist of a single atom with a positive or negative charge resulting from the loss or gain of electrons.
- 10. compound/ a compound that consists of positive and negative ions
- 12. polarity/ the uneven distribution of molecular charge
- 13. formula/ a representation of a substance using symbols for its constituent elements
- 17. covalent bond/ a covalent bond in which the bonding electrons are shared equally by the bonded atoms, resulting in a balanced distribution of electrical charge
- 18. bonding/ the intermolecular force in which a hydrogen atom that is bonded to a highly electronegative atom is attracted to an unshared pair of electrons of an electronegative atom in a nearby molecule
- 20. covalent bond/ a bond in which two atoms share two pairs of electrons
Down
- 1. covalent bond/ a covalent bond in which electrons are not shared equally
- 4. ions/ ions that are made of more than one atom
- 8. the simplest structural unit of an element or compound
- 9. formula/ a chemical formula showing the ratio of elements in a compound rather than the total number of atoms
- 11. covalent bond/ a bond formed when two atoms share a pair of electrons
- 13. bonding/ results from the sharing of electron pairs between two atoms
- 14. valence/ atoms gain more than 8 valence electrons
- 15. molecular compounds/ Non metal and a non metal has charges in the name
- 16. unit/ the simplest collection of atoms from which an ionic compound's formula can be established
- 19. energy/ the energy required to break a chemical bond and form neutral isolated atoms
