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!

The first step in creating a Lewis structure for a molecule is to determine the total number of valence electrons in the atoms that make up the molecule.

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 for k?
The Lewis dot structure for K (potassium) has one dot representing its valence electron. It is in the first group of the periodic table, so it has one valence electron.
How do you write a Lewis Dot structure of nicotine?
To draw the Lewis dot structure of nicotine, first determine the total number of valence electrons in the molecule. Then, arrange the atoms symmetrically with the central atom (usually nitrogen in the case of nicotine) in the center. Finally, place the valence electrons around the atoms to satisfy the octet rule, remembering that hydrogen atoms only need two electrons to fill their outer shell.
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.
Lewis dot structure of N3?
The Lewis dot structure of N3 (nitrogen trihydride) consists of three nitrogen atoms bonded together by covalent bonds, with each nitrogen atom having a lone pair of electrons. The structure appears as Nā”N-N with a total of 10 valence electrons.
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.
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
