Which is/are true about the atomic particles? [mark all correct answers] a. electrons are negative and repel protons. b. protons are positive and found inside the nucleus. c. neutrons are neutral and reside in the nucleus. d. neutrons and electrons have similar masses. e. protons are bound together by the strong nuclear force. f. electrons are attracted to protons but don't descend into the nucleus. g. electrons are smaller than protons and neutrons. h. a neutral atom has equal numbers of protons and neutrons?

a:

by the combination of an unlimited number of elements

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
