Chemistry

3. chemical compound whose simplest units are molecules
4. bond in which one pair of electrons is shared between two atoms
5. ability of a substance to be hammered or beaten
8. composed of positive and negative ions that are combined so that the numbers of positive and negative charges are equal
12. double and triple bonds
13. kind, number, Arrangement, and bonds but not the unshared pairs of the atoms in a molecule
15. formulas in which atomic symbols represent nuclei and inner shell electrons. Pairs or dashes between two Atomic symbols represent electron pairs in covalent bonds and. Adjacent to only one atomic symbol represent on shared electrons
17. chemical bonding that results from the attraction between metal atoms and the surrounding sea of electrons
18. energy required to break a chemical bond and form neutral isolated atoms
20. chemical bonding that results from the electrical attraction between cations and anions
23. Charged group of covalently bonded atoms

1. Mutual electrical attraction between the nuclei and valence electrons of different atoms that binds the atoms together
2. indicate relative numbers of atoms of each kind in a chemical compound by using Atomic symbols and numerical subscripts
3. neutral group of atoms that are held together by covalent bonds
6. electron configuration notation in which the valence electrons of an atom of a particular element are shown indicated by dots placed around element symbol
7. ability of a substance to be drawn, pulled, or extruded through a small opening to produce a wire
9. they have an uneven distribution of charge
10. energy released when one mole of an ionic crystalline compound is formed from gaseous ions
11. covalent bond in which the bonded atoms have an unequal attraction for the shared electrons.
14. bonding in molecules or ions that cannot be correctly represented by a single Lewis structure
16. types and numbers of atoms combined in a single molecule of a molecular compound
19. covalent bond in which the bonding electrons are shared equally by the bonded atoms resulted in a balanced distribution of electrical charge
21. results from the sharing of electron pairs between two atoms
22. simplest collection of atoms from which an ionic compounds formula can be written
