There are three known forms of hydrogen. these forms are called a. isotopes, b. copies, c. ions, of each other. each of these forms will have the same number of a. protons, b. neutrons, c. electron, but different numbers of a. protons, b. neutrons, c. electrons, in their nuclei.

Me i dont know what to do! the table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 10 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of the two atoms? both are unreactive. both are highly reactive. a is unreactive and d is reactive. a is reactive and d is unreactive.
