Ionic and Covalent Bonds
Across
- 2. atoms tend to gain, lose, or share electrons to achieve a stable electron configuration with eight valence electrons
- 4. they have a fully occupied outer shell
- 9. an ionic compound capable of conducting electricity as it is dissolved in a polar solvent
- 10. Elements on the right side of the periodic table that typically gain electrons in ionic bonding
- 12. covalent compound formed by the sharing of valence electrons between 1 carbon atom and 4 Hydrogen atoms (CH4)
- 15. this ionic compound has the chemical formula KBr
- 18. The outermost electrons of an atom; they are involved in bonding
- 19. group of two or more atoms held together by covalent bonds that has an overall electric charge
Down
- 1. An exception to the rule, this non-metal appears with the metals on the periodic table
- 3. The _______________ diagram shows an element's outer shells electrons
- 5. In a covalent bond, atoms _______ electrons to achieve the octet rule
- 6. when an ionic compound is formed, the charges of the individual ions add up to ___________.
- 7. chemical bond formed by the sharing of one or more pairs of electrons between two atoms
- 8. Elements found on the left side of the periodic table that typically lose electrons
- 11. ion with a negative charge that occurs when the number of electrons is greater than the number of protons
- 13. In an ionic bond, a metal ___________ electrons to a non-metal achieve the octet rule
- 14. ion with a positive charge that occurs when the number of protons is greater than the number of electrons
- 16. atom or molecule with a net electrical charge due to an imbalance between the number of protons and electrons
- 17. chemical bond formed by the losing/gaining of one or more electrons between a metal and a non-metal respectively.
