Cl has 7 electrons. If you draw Cl^-, there are 8 electrons and a minus 1 charge. What do you want to draw? And what do you mean by "odd" electrons?
Valence electrons are used to draw Lewis structures of molecules and atoms. These electrons are the outermost electrons of an atom that participate in bonding.
To draw a Lewis structure of a molecule or atom, you would typically use symbols to represent the atoms and lines to represent the bonds between atoms. The number of valence electrons for each atom is also considered to determine how the atoms are connected in the structure. Additionally, lone pairs of electrons on atoms are shown to complete their octets and achieve stability.
To draw a Lewis structure for Be2+, start by writing the symbol for beryllium. Since Be2+ has a 2+ charge, it has lost two electrons. Place the two electrons as individual dots around the beryllium symbol, as there is no other atom bonded to it. The Lewis structure for Be2+ is simply Be with two dots around it.
:CO draw 2 of the electrons to the left of carbon then 2 to the right and then draw 2 electrons of oxygen to its left and then the other 4 around the other sides of oxygen and draw a circle around the 2 electrons shared with carbon and the 6 existing electrons of oxygen then draw a circle around the 4 electrons carbon has and the 2 it shares with oxygen and after you've done all that, draw a bracket around the molecule and write -2 in superscript signifying that its net charge is -2
O(CH2)4NH you have to draw the O at the top of the ring with its two lone pairs, then on both sides is a C with two branching Hs and then continued around the hexagone like structure until you get to the bottom where you put an N with two lone pairs and a H branching off of it. Cant really draw it on here, but hope that helps!

The Lewis structure for HClO consists of one hydrogen atom bonded to one chlorine atom and one oxygen atom. The chlorine atom has two lone pairs of electrons and the oxygen atom has one lone pair. The oxygen atom is double bonded to the chlorine atom.

The answer is 12. If you draw the lewis dot structure for formaldehyde, you have to remember to draw the non-bonding pairs on the oxygen atom, and when you count all the electrons, remember that the lines used to represent bonds are counted as 2.
The Lewis structure for a nitric oxide ion (NO) has a nitrogen atom in the center with a single bond to an oxygen atom and a positive charge on the nitrogen atom.
To draw the Lewis dot structure for a molecule, first determine the total number of valence electrons for all atoms in the molecule. Then, arrange the atoms in the molecule, placing the least electronegative atom in the center. Next, connect the atoms with single bonds and distribute the remaining electrons as lone pairs to satisfy the octet rule for each atom. Finally, check that each atom has a full valence shell and adjust the structure if needed.

In the Lewis structure of CH2Br2, carbon is the central atom with hydrogen atoms on one side and two bromine atoms on the other. There are no nonbonding electrons on the central carbon atom. Each hydrogen atom contributes 1 nonbonding electron, and each bromine atom contributes 3 nonbonding electrons, resulting in a total of 8 nonbonding electrons in the molecule.
The Lewis structure for NH3 shows nitrogen in the center with three hydrogen atoms bonded around it. Each hydrogen atom is connected to the nitrogen atom by a single bond.
