Electron dot structure

a depiction of valence electrons around the symbol of an element


ionic compound
compound of cations and anions



valence electrons
an electron in the highest occupied energy level of an atom


ionic bond
the force of attraction binding oppositely charged ions


chemical formula
shows the kinds and numbers of atoms in the smallest representative unit of a substance


alloy
a mixture of two or more elements, at least one of which is a metal


octet rule
atoms in most compounds tend to achieve the electron configuration of a noble gas


formula unit
lowest whole-number ratio of ions in an ionic compound


metallic bond
the attraction of valence electrons for positive metal ions.


number of valence electrons in Group 6A
6


the charge on the resulting ion when an aluminum atom loses its valence electrons
3+


Metals are good conductors of electricity
they contain mobile valence elctrons



ionic compound
electrically neutral, held together by ionic bonds, composed of anions and cations.


not a characteristic of most ionic compounds
has a low melting point


metallic bond
bond between valence electrons and positively charged metal ions


chlorine and lithium
form an ionic compound


cation
any atom or group of atoms with a positive charge


chemical properties of an element are determined by the number of valence electrons the element has
Always true


Fluorine and chlorine each have one valence electron
