Do ions posses charges?
Yes, ions are charged molecules by definition. There are two types cations (with positive charges) and anions (with negative charges).
What kind of solution do all the molecules of an acid break apart in water?
When an acid dissolves in water, the molecules of the acid break apart into ions. Specifically, the acid molecules donate protons (H+ ions) to the water molecules, resulting in the formation of hydronium ions (H3O+) and negatively charged ions from the acid. This process is called ionization or dissociation.
Why do acids or bases dissociate?
polar water molecules pull apart the acid or base by pulling on the charged ions.
What are positively and negativity charged ions?
Ions are molecules which have gained (negative) or lost (positive) an electron. Positive Charge are called Cations. Negative Charge are called Anions.
Charged atoms are called?
Charged atoms are called ions.
Do giant covalent structures contain charged ions?
yes
Why do ionic compounds behave somewhat like polar molecules in a solution?
Because they dissociate into charged ions. Because they dissociate into charged ions.
When atoms gain or lose electrons the charged particles that result are called molecules?
NO, they are called ions.
What form of atoms or molecules form ionic bonds?
Ions, charged atoms
How do water molecules interact with charged material?
Water molecules are polar. Charged particles such as ions attract water molecules. Positive ions often have a "shell" of water molecules around them, pointing their negative O atoms at the central ion, both in solution and in the solid forms (hydrates)
What are atoms called that hsve the same number of protons but different numbers of electrons?
Ions. They are charged molecules or charged atoms.
Particles formed from covalent bonding is?
They are molecules.No they are generally called molecules. However there are polyatomic ions that are charged molecules, such as SO42-
Why there are no molecules in ionic compound?
Ionic compounds contain ions, there are no neutral molecules. These are often charged atoms as in NaCl but may be polyatomic ions such as NH4+ which contains covalent bonds
Do ions posses charges?
Yes, ions are charged molecules by definition. There are two types cations (with positive charges) and anions (with negative charges).
What does electrolysis use to separate molecules in a chemical change?
The electrolysis ionize the particles/ molecules present in the particles and charged the positive and negative ions. Positive ions collected on negative electrode and Negative ions collected on positive electrodes.
What kind of solution do all the molecules of an acid break apart in water?
When an acid dissolves in water, the molecules of the acid break apart into ions. Specifically, the acid molecules donate protons (H+ ions) to the water molecules, resulting in the formation of hydronium ions (H3O+) and negatively charged ions from the acid. This process is called ionization or dissociation.
What are the substances that the cell membrane does not allows to pass?
Usually Ions and charged molecules (salts dissolved in water), large polar molecules (glucose), and macromolecules.
