What describes the current model of the atom? select one: a. that electrons and protons move randomly around a nucleus. b. electrons travel as waves in the electron cloud that surrounds the nucleus. c. electrons orbit the nucleus like planets orbit the sun. d. protons orbit the nucleus like planets orbit the sun.

In which of these cases are the two wave points considered to be in phase with each other?

Both josef loschmidt and amedeo avogadro contributed to our understanding of basic molecular numbers, sizes, and reaction ratios. neither scientist discovered “avogadro’s number” in the form we use it today (6.02 x 10 23). still, there’s a controversy over the name. research the contributions from these two scientists and read about how avogadro’s number got its name. briefly state what you think this number should be called, providing key details of each scientist’s contributions to this concept and a solid rationale for your case in naming the number.

Three alkali metals in group 1 are a. calcium, strontium, barium b. boron, aluminum, gallium c. sodium, potassium, rubidium d. fluorine, iodine, chlorine
