Also, by electron charge, are you referring to the opposite of elementary charge? The systematic name is monohydrogen carbonate(-1), this tells you the formal charge, as would simply adding the charges using the chemical formula of bicarbonate. [HCO3]-
The bicarbonate ion bonds to monovalent cations like sodium. This means that under normal conditions the bicarbonate ion has one electron available for bonding.
bicarbonate ion is HCO3-. Each oxygen has two non-bonding electron pairs, so there are six in total.
There are eight pairs of bonding electrons - two pairs between carbon and oxygen and one pair between each hydrogen and the carbon.
23 valence electrons

A phosphorus atom has one nonbonding pair of electrons.
1 pair. which means 2 nonbonding electrons.
There are two pairs of nonbonding electrons in a chloroform molecule. Each chlorine atom contributes one nonbonding pair of electrons, resulting in a total of two pairs of nonbonding electrons in the chloroform molecule.
An HCl molecule contains 3 nonbonding pairs..
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.

H2CO. The oxygen will have two pairs of non-bonding electrons
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.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
3 Lone pairs and one unpaired electron
Zero
None; the oxygen has 2 missing "spaces" for electrons. The two hydrogens have 1 missing "space" for an electron each. Through sharing, all of the atoms fulfill the octet rule. (8 e- in outermost orbital)
