25. which one of the following is not one of the postulates of dalton's atomic theory? a) atoms are composed of protons, neutrons, and electrons. b) all atoms of a given element are identical; the atoms of different elements are different and have different properties. c) atoms of an element are not changed into different types of atoms by chemical reactions: atoms are neither created nor destroyed in chemical reactions. d) compounds are formed when atoms of more than one element combine; a given compound always has the same relative number and kind of atoms. e) each element is composed of extremely small particles called atoms.

Astudent made the lewis dot diagram of a compound as shown. mg is written with two dots shown on its top. an o is written on each side of mg. each o has six dots around it. an arrow is shown from one dot on mg toward the vacant space around the o on the right. another arrow is shown from the other dot on mg toward the vacant space around the o on the left. the title of the art is students lewis dot model. what is the error in the lewis dot diagram? an o atom should transfer all its six electrons to mg because the formula is mgo. both electrons of mg should be transferred to one o atom because the formula is mgo. the electrons should be transferred from each o atom to mg because mg has fewer electrons. the number of dots around mg should be four because it has to transfer two electrons to each o.
