True. Isotopes are defined by the amount of neutral neutrons which have no effect on the polarity of the atom. ions are defined by a differing amount of protons and electrons, therefore charging them.
Not necessarily no, not strictly speaking, but it can be. An Ion is a charged particle. As an example SO42- is an ion. It is not a charged atom. It is a charged species formed from 5 atoms. A lone proton (H+ ) is a charged atom of hydrogen after it has been stripped of one electron. Cl- is an ion and in this case yes - it is a charged atom.
True. Metals typically form cations by losing electrons to achieve a stable electron configuration. This results in a positively charged ion that is attracted to negatively charged species, such as nonmetals or other negative ions.
False. In a neutral atom, the number of electrons is equal to the number of protons. This balance between positively charged protons and negatively charged electrons is what keeps the atom electrically neutral.
A substance that forms hydroxide ions in a water solutoin is a base -- TRUE -- apex:)
Protons are positively charged but found in the NUCLEUS (so false). Electrons are found in the orbitals (but are negatively charged)
False. Ions are formed from the loss or gain of electrons by atoms, resulting in a charged particle. Covalent bonding involves the sharing of electrons between atoms.

True. In ionic compounds, atoms transfer electrons to achieve a more stable electron configuration. This results in the formation of positively charged ions (cations) and negatively charged ions (anions), but the total charge of the compound remains neutral.
true
False. Number of neutrons.
True. Molecular compounds that dissolve in water do not conduct electricity because they do not dissociate into charged ions when dissolved. Since they do not produce free ions that can carry an electric current, they are unable to conduct electricity in aqueous solutions.
False. In a neutral atom, the number of electrons is equal to the number of protons. This balance between positively charged protons and negatively charged electrons is what keeps the atom electrically neutral.
True. Binary ionic compounds consist of a positively charged metal ion and a negatively charged nonmetal ion. These ions usually come from opposite sides of the periodic table.
No, it's called "radioactive." "Retroactive" is something that's active in regards to the past.
