Question | Answer |
What is the Lewis Structure? | a combination of Lewis Symbols that represent either the transfer or the sharing of electrons in chemical bonds. |
what is a valence structure? | the electrons in the outermost shell. |
what is a valence shell? | outermost shell of electrons |
what is the octet rule? | that only 8 electrons can be in a outershell(valence shell/level) of an atom- except for H and He who have one shell containing maximum number of electrons of 2 electrons |
what is ionic bonding? | chemical bond formed from the transfer of electrons between two or more atoms. |
what is an ionic compound? | a compound that has ionic bonds |
what is an ion? | an atom with either a negative charge or a positive charge which is due to the gaining or losing of electrons |
what is the name of a positive ion? | cation |
what is the name of a negative ion? | anion |
what is a oxidation number? | it is a subscript that represent the charge if a ion. |
what is a binary compound? | a compound where 2 elements( a metal and a nonmetal) are present |
what is the correct way to form a binary compound? | the oxidation number of the atoms must equal 0 |
what is a ionization energy? | energy required to remove the most loosely held electron from the outer shell of an atom. |
How can you tell which atoms have higher ionization energy by looking at the periodic table? | ionization energy increases as one goes up and to the right of the periodic table. Fl has the highest ionization energy |
