Which of the following was not postulated by Dalton? Group of answer choices A, Atoms of one element differ in properties from atoms of all other elements. B, Atoms can be decomposed into smaller particles protons, neutrons, and electrons. C, An atom is the smallest unit of an element that can participate in a chemical change. D, Atoms are neither created nor destroyed during a chemical change, but are instead rearranged
In 1911, Hans Geiger and Ernest Marsden, working under Ernest Rutherford, conducted an experiment involving alpha particles and gold foil that led to the discovery of the nucleus in atoms. The nucleus of an atom accounts for O most of the size and mass of the atom. O very little of the size and mass of the atom. O most of the atom's size but very little of its mass. O most of the atom's mass but very little of its size. 15 N 4 stv W MacBook Air
May I ask, Why and how does the mass number change in different questions? For example, in the question "An ion with 53 protons, 73 neutrons, and 54 electrons." this I iron's mass number is 126, but in periodic table, it shows I atom's mass number is 126.9 Another example, "An ion with 24 protons, 26 neutrons, and 21 electrons", this Cr ion's mass number is 50 while in periodic table Cr atomic mass is 52. I'm confused about how the mass number is changing, does it also change according to electrons? isn't mass number supposed to be realted to just protons and neutrons? Or the way I am understanding the concepts and their relationships are wrong? Thank you!!
