We know that a neutral atom of bromine (br) is larger than a neutral atom of magnesium (mg) because a.) group numbers tells us how many electrons orbitals surround a nucleus, bromine is in group 7a while magnesium is in group 2a b.)period numbers tells us how many electron orbitals surround a nucleus, bromine is in period 4 while magnesium is in period 3 c.)atoms with many electrons are always larger than atoms with fewer electrons, a neutral atom of bromine has 35 electrons while neutral atom of magnesium has only 12. d.) bromine and magnesium has very different physical and chemical properties.

Juju.01) 5 geologic events a group of students designed an experiment in an ice rink to represent the solar system. the steps of the experiment are listed below. 5: geologic events 1. choose a student to represent the sun. the planets are represented by two tennis balls. 2. ask the student to hold the tennis balls in each palm and spin on the ice with arms stretched out. 3. ask the student to draw in the arms after about 10 spins. 4. observe the student's arms rotate faster when they are closer to the body. 05 geologic events enors) the experiment most likely demonstrates that (2 points) 07 discussion-based sessment/module planets exert gravitational force on the sun the sun exerts gravitational force on the planets 3.07 discussion-based ssessment speed of a planet depends on its distance from the sun new version available!
