When an atom gains or loses a valence electron, it forms an ion. Atoms form ions in order to help another to obtain a full octet and to stabilize the valence.

Does the acide or alkaline increase rusting?
Rust formation is accelerated in the presence of acid. One of the byproducts of rust is the formation of hydroxide ions. Acid neutralises these ions allowing more to form.
How would you compare the formation of positive ions with the formation of negative ions in terms of energy changes?
when a negative ion forms electrons are gained and energy is given off and when a positive ion forms electrons are lost and energy is used.
Dissolving an electrolyte in water results in the formation of?
a decrease in the vapor pressure of the liquid
Are ions in a ionic compound in a lattice formation?
At least, one anion and one cation participate in forming a crystalline ionic lattice. Every ionic compound forms a lattice, they do not form molecules.
What is a standard formation reaction?
A standard formation reaction is the reaction of the ions which make up a compound in their standard states. For example, the standard formation reaction of H2SO4 is: 2H+(g) + SO42-(g) --> H2SO4 (l)
Can you explain formation of sodium chloride from sodium and chloride ions?
Sodium ions have positive charge whereas chloride ions have negative charge. They alternatively form electrostatic bonds to create the NaCl lattice which is ionic.
Does the acide or alkaline increase rusting?
Rust formation is accelerated in the presence of acid. One of the byproducts of rust is the formation of hydroxide ions. Acid neutralises these ions allowing more to form.
Is energy required or released in the formation of negative ions?
ergy is released in the formation of negative ion
What is dissociation of water mean?
This is the formation of the ions H+ and OH-.
What is the formation of ions when a solvent acts on a solute?
i think its ionization
Does energy always released during ionization?
During the formation of anions (negatigely charged ions) energy is released. During the formation of cations (positively charged ions) energy is absorbed.
Why formation of ADP from ATP release more energy then formation of AMP from ADP?
20 ions are broken down
What is the importance of ionzation energy in the formation of ions?
The meaning of a high ionization energy is that the formation of an ion is more difficult.
What is the heat of formation of n2O4?
The heat of formation of zinc nitrate is -2304 kJ.
what is the negative ion?
an atom with one or more extra electron(s) in its valence band. There are also molecular ions but they are more complicated to explain than simple atomic ions.
What does the nebular hypothises explain?
the formation of the universe
How many potassium ions are needed to balance the charge of one sulfide ion Explain?
Two. the sulfide ion is S2- so two K+ ions are required to balance the charges
