For each atom, determine how many dots should be drawn around the element symbol in the Lewis structure for a lone, neutral atom. The Lewis structure of an oxygen atom should have dots drawn around the symbol O.
The Lewis structure of a calcium atom should have dots drawn around the symbol Ca.
The Lewis structure of a nitrogen atom should have dots drawn around the symbol N.
The Lewis structure of an aluminum atom should have dots drawn around the symbol Al.
The Lewis structure of a fluorine atom should have dots drawn around the symbol F.
Identify each term as a description of an electron geometry or a molecular geometry.
Trigonal pyramidal for NF3
Arrangement of bonding and non-bonding electron domains
Tetrahedral for NF3
Arrangement of only the atoms in a molecule
When drawing the Lewis structure of the HCCI: molecule, the structure should represent a total of 26 valence electrons. What is the best description of the complete Lewis structure of the molecule?
A. A H atom should be in the center with single bonds to each Ci atom and a double bond to the Catom.
B. A C atom should be in the center with a double bond to the H atom and double bonds to each Cl atom.
C. A C atom should be in the center with single bonds to each Ci atom and a single bond to the H atom.
D. A CI atom should be in the center with a single bond to the Catom and a single bond to the H atom
