When a bond in water molecule H20 breaks it forms H+ and OH-. The extra electron comes from H.
H-O-H ------> H+ + OH-
The extra ATP molecules needed for the Calvin Cycle come from the light-dependent reactions of photosynthesis, specifically from the electron transport chain in the thylakoid membrane. Here, the energy from sunlight is used to generate ATP through the process of photophosphorylation.
When a fluorine atom attracts an extra electron from a lithium atom, the lithium atom loses one electron and becomes positively charged, forming a lithium ion (Li⁺). Meanwhile, the fluorine atom gains the extra electron, becoming negatively charged and forming a fluoride ion (F⁻). This transfer of electrons results in the formation of an ionic bond between the two ions.
The halogen ions are big compared to their normal atoms as they gain one extra electron because of the resultant ionic bond that is formed.
No, Neon does have 10 electrons but it has no charge
Donor atoms are atoms that donate electrons and have an extra pair of electrons in their orbital. Acceptor atoms are atoms that accept electrons and have a empty orbital to accommodate the extra electrons.
The formula for the hydroxide ion is OH-. It has a charge of -1 due to the presence of one extra electron compared to the number of protons in the oxygen atom.
The valency of the aluminate ion ((Al(OH)_4^-)) is -1, as it has one extra electron compared to a neutral aluminum atom. The formula for the aluminate ion is (Al(OH)_4^-).
An atom with one extra electron is called an anion, while an atom with one missing electron is called a cation.
Hydroxide (OH-) has a negative charge because it has gained an extra electron, giving it a net negative charge of -1. This extra electron is acquired when a hydrogen ion (H+) is donated to the hydroxide ion as part of a chemical reaction.
Anion.
The extra ATP molecules needed for the Calvin Cycle come from the light-dependent reactions of photosynthesis, specifically from the electron transport chain in the thylakoid membrane. Here, the energy from sunlight is used to generate ATP through the process of photophosphorylation.
The fluoride ion is larger than the fluoride atom because it has gained an extra electron, resulting in an increase in electron-electron repulsions, which causes the electron cloud to expand. This increase in electron-electron repulsions leads to a larger ionic radius compared to the atomic radius of the fluoride atom.
The hydroxide ion (OH⁻) consists of one oxygen atom and one hydrogen atom. Oxygen has six valence electrons, and hydrogen has one, giving a total of seven. However, since OH⁻ has an extra electron due to the negative charge, it has a total of eight valence electrons.
If a fluorine atom were to attract an extra electron from a lithium atom, the lithium atom would become a positive charge because it loses an electron.
It has a negative charge.
A hydroxide ion (OH-)hydroxide ion
The notation for a hydroxide ion is OH-. It consists of one oxygen atom and one hydrogen atom bonded together with a single covalent bond. The negative charge is due to the extra electron that the oxygen atom brings to the ion.
