nomenclature
zinc iodide
ZnI₂
Iron(II) acetate
Fe(C2H3O2)2
how do you find hybridization
How do you find D hybridization?
start with sp3, subtract P for every pi bond
(do you know when to add d?)
trend of electronegativity on the periodic table
what is the most electronegative element?
increases up the column and across the row
Flourine!
chlorous acid
HClO2
tin (II) permanganate
Sn (MnO4)2
what are sigma and pi bonds
Sigma bonds (σ) are the first type of covalent bond, formed by overlap of atomic orbitals head-to-head. They are found in single, double, and triple bonds. Pi bonds (π) are the second and third types of covalent bonds, formed by overlap of p orbitals side-to-side. They only exist in double and triple bonds.
increases across rows and up columns
what is the difference between sulfate and sulfite?
(these are polyatomic ions!)
the number of oxygen atoms and the oxidation state of the sulphur present
sulfate- SO4
sulfite- SO3
note:(both have a -2 charge)
CuBr
copper (I) bromide
what type of bond is formed with a metal and a nonmetal?
what bond is formed with two or more nonmetals
ionic- m and nm
covalent- nm and nm
trend of atomic radius
increases down the rows and decreases across columns
lithium hypochlorite
LiClO
titanium (IV) chloride
TiCl4
what is crystal lattice structure
the symmetrical three-dimensional structural arrangements of atoms, ions or molecules (constituent particle) inside a crystalline solid as points
how do you know is a molecule is polar or nonpolar
remember the electronegativity and which atom is pulling the electrons
nonpolar- symmetrical pulling
polar- non symmetrical, the more electronegative element is pulling the electrons.
(what direction does the dipole go?)
Sr(HCO3)2
strontium hydrogen carbonate
Iron(III) carbonate
Fe2(CO3)3
the electron and molecular geometry of H2O
electron geometry is tetrahedral
molecular geometry is bent
