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
8
A phosphorus atom has one nonbonding pair of electrons.
1 pair. which means 2 nonbonding electrons.
An HCl molecule contains 3 nonbonding pairs..
H2CO. The oxygen will have two pairs of non-bonding electrons
The carbon is in the middle; this is a tetrahedral shape, and there are zero lone pairs.

H2CO. The oxygen will have two pairs of non-bonding electrons
The carbon is in the middle; this is a tetrahedral shape, and there are zero lone pairs.
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)
