The given statement “hydrogen is most stable when it has a full octet of electrons” is .
Further explanation:
<u>Chemical bond: </u>
The attraction between atoms, molecules or ions that is responsible for the formation of chemical compounds is known as a chemical bond. It is formed either due to electrostatic forces or by the sharing of electrons. There are many strong bonds such as ionic bonds, covalent bonds, and metallic bonds while some weak bonds like dipole-dipole interactions, London dispersion forces, and hydrogen bonding also exist.
<u>Octet rule: </u>
According to this rule, the elements have the tendency to bond with other elements in order to acquire eight electrons in their valence shells. This results in achieving a stable noble gas configuration. Generally, all elements obey octet rule but there are some exceptions to this rule. For example, Be and B do not follow the octet rule.
The atomic number of hydrogen is 1 so its electronic configuration is . The maximum number of electrons that can be accommodated in the s orbital is two. So hydrogen can form one single bond with any other element and occupy two electrons in its valence shell. Therefore duplet of hydrogen is filled. But octet rule states that there should be eight electrons in the valence shell of the atom in order to acquire stability. Hydrogen is an exception to the octet rule. Therefore the given statement is false.

The chemical formula of malonic acid is CH2(COOH)2. Malonates include the ionized form of malonic acid as well as its esters and salts. For instance, the diethyl ester of malonic acid is called diethyl malonate.
Polyester and polymers both employ malonic acid as a precursor. Both the scent business and the flavoring sector utilize it. It is employed to regulate acidity. Malonic acid contributes to the production of fatty acids in people. Malonic acid has been found in a number of foods outside of the human body, including red beets, corn, scarlet beans, common beets, and cow milks, although its presence has not been defined. The group of organic substances known as dicarboxylic acids and derivatives includes malonic acid, also known as malonate or H2MALO.
