a chemical bond in which one atom loses an electron to form a positive ion and the other atom gains to electron to form a negative ion
a chemical bond in which electrons are shared over many nuclei and electronic conduction occurs
a mixture containing two or more metallic elements or metallic and nonmetallic elements usually fused together or dissolving into each other when molten
atoms of a different element "fill in gaps" in between the original metal atoms.
the energy released when one mole of an ionic crystalline compound is formed from gaseous ions
electron sea model
proposes that all metal atoms in a metallic solid contribute their valence electrons to form a "sea" of electrons, and can explain properties of metallic solids such as malleability, conduction, and ductility
properties of metals
shiny, ductile, good conductor of electric current, malleable, good conductor of thermal energy
a bond formed when two atomic orbitals combine to form a molecular orbital that is symmetrical around the axis connecting the two atomic nuclei
A covalent bond in which the bonding electrons are most likely to be found in sausage-shaped regions above and below the bond axis of the bonded atoms
Lewis structures that have the same arrangement of atoms in a molecule but differ in the distribution of electrons among the atoms.
(genetics) the act of mixing different species or varieties of animals or plants and thus to produce hybrids
States that atoms lose, gain or share electrons in order to acquire a full set of eight valence electrons
consists of the symbol of an element and one dot for each valance electron in an atom of an element
polar covalent bond
A covalent bond between atoms that differ in electronegativity. The shared electrons are pulled closer to the more electronegative atom, making it slightly negative and the other atom slightly positive.
an arrangement of atoms in the VSEPR model where the three pairs of electrons are placed 120 degrees apart on a flat plane.
net ionic equation
includes only those compounds and ions that undergo a chemical change in a reaction in an aqueous solution
a representation of a chemical reaction that uses symbols to show the relationship between the reactants and the products
a chemical reaction in which one element replaces another in a compound, or when two elements in different compounds trade places
the SI base unit used to measure the amount of a substance whose number of particles is the same as the number of atoms of carbon in exactly 12 g of carbon-12
compound that has water chemically attached to its ions and written into its chemical formula
