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.

Are ions and isotopes charged?
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.
The concentration of hydrogen ions in solution is the pH of the solution the answer has to be either true or false?
False.
True or false two isotopes of carbon are carbon-12 and carbon-14 theese isotopes differ from one another by two ELECTRONS?
False, different isotopes of the same element have different numbers of neutrons.
3 All nuclear radiation consists of charged particles true or false?
False, neutrons are not charged and gamma rays aren't charged particles.
Do proteins prevent ions form crossing cell membranes true or false answer?
True

Is it true or false molecular compounds that dissolve in water do not conduct electricity because no charged ions are present?
That, for the most part, would be true. If the compound is truly molecular, then ions would not form, and it would be a non electrolyte.
A negatively charged atomic particle is called an electron?
It is true that a charged particle is called an ion. Ions that are positively charged are called cations and ions that are negatively charged are called anions.
Ions are randomly arranged in ionic solids true or false?
false
Is an acid a substance that produces hydroxide ions in a water solution?
False
Are radioactive isotopes are used in medicines or power plants and tracers true of false?
true
The atomic number of isotopes is determined by the number of atoms. true or false?
False. Number of neutrons.
True or false unstable atom that decomposes and emits energy is called retroactive?
No, it's called "radioactive." "Retroactive" is something that's active in regards to the past.

False.
