Bicarbonate, also known as HCO3, is a byproduct of your body’s metabolism.

Sodium bicarbonate is formed by mixing carbon, sodium, hydrogen and oxygen molecules. This mixture, also known as baking soda, is actually a type of salt.

Carbonate Ion is a polyatomic ion with formula of CO3(2-). NCI Thesaurus (NCIt) Carbonate is a carbon oxoanion.

Carbonates (CO3–) are actually weak bases. Carbonic Acid (H2CO3) breaks apart to form H+ and HCO3- or to make two H+’s and CO3–.

The substance with the chemical formula CO3 goes by the name carbonate. Carbonate is made of 1 atom of carbon and 3 atoms of oxygen and has an electric charge of −2. This negative charge means that a single ion of carbonate has 2 more electrons than protons.

Sulfur trioxide, a chemical compound of sulfur. Sulfite, a chemical ion composed of sulfur and oxygen with a 2− charge.

-2

⇒ Sulphate Ion Formula: SO42- Sulphate is basically a chemical compound that is composed of sulphur and oxygen atoms.

Sulfate Formula The molecular formula for sulfate is SO42-. Four bonds, two single and two double, are shared between the sulfur and oxygen atoms. The -2 you see on the sulfate ion reminds you that this molecule is charged. This negative charge comes from the oxygen atoms that surround the sulfur atom.

In the lewis structure of PO43-, three is a double bond between phosphorous atom and one oxygen atom. Between other oxygen atoms, there are only single bonds with phosphorous atom. Also, each oxygen atom has a -1 charge.

Phosphate

There are three violations to the octet rule: odd-electron molecules, electron-deficient molecules, and expanded valence shell molecules.

BCl3 do not obey octet rule.It is a electron deficient molecule.As it share only three electron with chlorine atom . After forming a molecule boron has only six electrons I.e three from chlorine atom and three of its own. Nitrogen molecule will be achieving octet by sharing three electrons.

From the structure “Se” have four bonds. And central atom “ Se” surrounded by eight bonding electrons and one pair of nonbonding electrons . Hence ,SeF4 does not obey the octet rule.

Period 3

Answer. Answer: Explanation: only N2O3 molecule follow octet rule.

Oxygen has no empty orbitals with it . It only possess orbitals upto 2p which contains 4 electrons. So it cannot expand its octet by exiting it’s electrons.

Atoms come together to form molecules because of their electrons. Electrons can join (or bond) atoms together in two main ways. When two atoms share electrons between them, they are locked together (bonded) by that sharing. Bonds like this are in oxygen gas, nitrogen gas, and hydrogen gas.

In the sense that living organisms reproduce, no, atoms do not reproduce. Some atoms are radioactive and decay into other atoms. Some emit “alpha” particles when they decay. An alpha particle is two protons and two neutrons stuck together.

When an atom has an equal number of electrons and protons, it has an equal number of negative electric charges (the electrons) and positive electric charges (the protons). The total electric charge of the atom is therefore zero and the atom is said to be neutral.

A molecule is formed when two or more atoms join together chemically. If atoms combine that are of two or more different elements, we call that a compound.

neutron: A subatomic particle forming part of the nucleus of an atom. It has no charge. It is equal in mass to a proton or it weighs 1 amu.
