How atoms interact with other atoms is largely dependant on the number of electrons on its outermost layer. The electrons on this layer are called valence electrons.

As you might know, atoms have their electrons arranged in layers/shells, starting at k, l m, n etc. Each layer has a maximum number of electrons it can accommodate, with the outermost one being the valence shell. The first layer (k) can accomodate 2 electrons, the second one (l) can accomodate 8, as can the third one (m) etc.

As a rule of thumb, most atoms don't like being alone. These atoms have a valence shell that isn't saturated. This is the case for hydrogen(1), with one free slot in its outter shell.

However, atoms like helium are a bit different. They are inert, and don't need to bond with other atoms. This is because their valence shell is saturated. In this case, helium saturated the k shell with 2 electrons. Helium in this form will not form bonds.

However, hydrogen is still out there looking for buddies. Hydrogen will bind with any other atom with a free electron. Being extremely common, it's likely that said atom will be another hydrogen.

However, another common example would be for 2 hydrogens to bond with one oxygen, forming h2O (oxygen can form 2 bonds)

Conclusion : helium is inert and will not interact with other atoms. Hydrogen is not, and thus needs to bond with other atoms.

The immediate electron acceptor for the majority of the oxidative reactions of the citric acid cycle is.
Anna [14]

NAD serves as the bulk of the oxidative processes in the citric acid cycle's initial electron acceptor.

<h3>What are electron acceptors in citric acid cycle?</h3>
  • In the Krebs cycle, which transfers electrons via the electron transport chain with oxygen as the final acceptor, coenzymes like FAD and NAD+ are reduced.
  • In a single cycle, three NADH+ and one FADH2 are produced, and when the cycle enters the electron transport chain, 10 ATP is produced.
  • The final electron acceptor in the electron transport chain is oxygen. The proton gradient in the intermembrane gap is produced by NADH molecules donating electrons that are then transmitted through a number of different proteins.
<h3>What occurs throughout the citric acid cycle?</h3>

The cycle of citric acid: In the citric acid cycle, a six-carbon citrate molecule is created when an acetyl group from acetyl CoA is joined to a four-carbon oxaloacetate molecule.

Citrate is oxidized over a number of steps, generating two molecules of carbon dioxide for each acetyl group added to the cycle.

If a compound has a molar más of 180g/mol and it’s empirical formula is CH^2O, what is it’s molecular formula?
lesya [120]

C: 12.0107 g/mol ≅ 12.00 g/mol

H: 1.00784 g/mol ≅ 1.008 g/mol

O: 15.999 g/mol ≅ 16.00 g/mol

n(molar mass of CH2O)= 180

n.30=180

n=6

molecular formula: c6h12o6 glucose
