What is the first step in creating a Lewis structure for a molecule?

You need to know how many valence electrons the molecule has. Then determine the number of bonding pairs, and place them in their order. Remember that all molecules strive to reach the octet rule! which means they all wants to have a full eight electrons for their outer energy level. good luck!

What is the hybridization of the central sulfur atom in SF4?
It should be sp3d. first draw the Lewis structure. then you can see the central S atom has 4 bonding pair and 1 lone pair. then draw molecular orbital. Distribute electron according the bonding and lone pair. the paired electron represent lone pair in Lewis structure. and the other unpaired electron distribute in the molecular orbital represent the number of bonding pair in Lewis structure
What is the Lewis dot structure of H2O?
since the molecule is actually H30+, the number of electrons total in the molecule is (3(1)+6)-1=8 so the structure is oxygen as the center atom and the three hydrogens attached to the oxygen with a lone pair on the oxygen as well. this gives 3(6)+2 which is 8 electrons total.
Is NH4 linear?
No. First of all, NH2- is an ion, not a molecule. Second, it has a bent geometry, similar to that of a water molecule.
Lewis theory of acids and bases?
Lewis acid is an electron acceptor / Lewis base is an electron donor. It is helpful to use this definition of acid and base in (1) organic chemistry (2) also when there are no Hydrogens present in the molecule. BF3 is a Lewis acid it seeks out and can accept electrons.
Why do water molecules form a lattice structure?
Water is H2O. The hydrogen molecule has 1 electron and it needs to fill the first shell. Oxygen has a complete first shell and six electrons in the second. The second shell needs eight to be complete. So a bond of two hydrogen atoms and one oxygen molecule is very stable. The way the two elements combine has the oxygen molecule in the middle and the two hydrogen atoms in a tetrahedral pattern.
What is the first thing you should do if you want to determine if a molecule is polar or not?
Draw the Lewis Structure
How to know if a substance is a polar or not?
First of all you have to draw the Lewis dot structure of the molecule. If the molecule is symmetrical, it's non-polar. If the molecule is non-symmetrical or asymmetrical, then the molecule is polar.
Which Lewis structure represent an atom x in period 4 with the highest first ionisation energy?

Who offered the model of DNA molecule structure?
The helical nature was discovered by Rosalind Franklin and Watson and Crick first built the model of it.

Is sil4 polar or non polar and why?
Silica is polar.This is because of two things: first of all, each individual bond in the molecule is polar, due to the high electronegativity difference between silicon and oxygen. Secondly, the structure of silica is similar to that of water, creating two distinct sides of different charges and therefore a strong dipole.
What is the Lewis dot structure of H2O?
since the molecule is actually H30+, the number of electrons total in the molecule is (3(1)+6)-1=8 so the structure is oxygen as the center atom and the three hydrogens attached to the oxygen with a lone pair on the oxygen as well. this gives 3(6)+2 which is 8 electrons total.
Which step happens first in DNA replications?
The first thing that happens is a replication structure binds to the DNA molecule. This is usually a signalling molecule or some type of protein. Next, this replication structure attracts DNA helicase enzymes which "unzip" the double stranded helix.
What is the first name of Inspector Lewis?
Inspector Lewis' first name is Robert.
This is the structure of DNA as first published by James Watson and Francis Crick in 1953.?
That DNA molecule is a double helix-two strands twisted around each other, like a winding staircase
What is the correct Lewis structure for an Nitrogen atom?
Two electrons in the first shell (closest to the nucleus), then five on the next shell out, usually shown as a pair and 3 singles.
What are isovalent hyperconjugation structures?
(physical chemistry) An arrangement of bonds in a hyperconjugated molecule such that the number of bonds is the same in the two resonance structures but the second structure is energetically less favorable than the first structure; examples are H3CC+H2 and H3CCH2.
