|What are Ionic Bonds? What type of atoms bond ionically?||Bonds in which atoms gain or lose e⁻. Between metals and nonmetals.|
|What are covalent bonds? What type of atoms bond covalently?||Bonds in which atoms share e⁻. Between nonmetals.|
|Main difference between writing lewis structures for ionic compounds vs. molecular compounds?|| Ionic: nonmetals and metals. Transfer e⁻. Have positive or negative charges.|
Covalent: nonmetals, share e⁻. Have no charges.
|What is electron configuration?||arrangement of electron in atomic orbitals|
|What is atomic radius?||The distance from the nucleus.|
|What is the trend in atomic size and why does this occur?|| From left to right, atomic radius decreases as increasing number of electrons pull the shell closer to the nucleus. |
Going down columns, radius increases due to the addition of another she..
|What is ionization energy?||energy required to remove an electron from an atom|
|What trends occur for ionization energy and why does this occur?|| Left to right: Increases b/c there are more protons in the nucleus.|
Up & down: decreases b/c of the distance between the nucleus and the valence electrons
|What is electronegativity?||Attraction for electrons|
|What trend occurs for electronegativity and why does this occur?|| Left to right: Increases because the number of charges on nucleus increases. |
Up and down: decreases because bonding pair of electrons ins increasing distant from the attraction of the nucleus.
|What are the three main parts of an atom? Which has the least mass?|| Electron: e⁻ mass, |
