Why can a hydrogen atom form a covalent bond without fulfilling the octet rule?

2 answers:

8 0

Bromine forms covalent bonds because it has seven valence electrons, but neon has eight valence electrons and already fulfills the octet rule. The compound cyanogen (CN)2 has covalent bonds shown in this diagram.

The answer is: Hydrogen's valence shell can hold only up to two electrons.

Hydrogen (symbol: H) is a chemical element with atomic number 1, which means it has one proton and one electron.

Electron configuration of hydrogen atom: ₁H 1s¹.

In s orbital maximum number of electrons is two.

Hydrogen form bonds with electrons as closest noble gas helium (He).

Explain how there can be more heat energy in an iceburg than in a pot of boiling water

vlada-n [284]

Heat energy is the amount of heat there is in a substance. This may be cold heat or warm heat. Temperature is how hot or cold a substance is. So because there is a higher volume of heat in the iceberg, we say it has more heat energy.

When NAD becomes NADH, it is being reduced and gaining chemical energy.

Nicotinamide adenine dinucleotide (NAD), a coenzyme, can exist in two forms, NAD⁺ (oxidized) and NADH (reduced form).

Electrons and protons released in catabolism reactions are attached to NAD⁺. The conversion of NAD⁺ to NADH is important reaction for production of ATP during the cellular respiration.

Reduction is lowering oxidation number because element, ion or compound gain electrons.

Chemical equation for reaction of reduction of NAD⁺ (see picture below):

NAD⁺ + 2e⁻ + H⁺ → NADH

Nicotinamide adenine dinucleotide (NAD) is made of two nucleosides joined by pyrophosphate.
