The atom is the basic unit in chemistry. an atom contains neutrons, protons, and electrons. neutrons are neutral, protons have a positive charge, and electrons have a negative charge. most of the time, atoms are neutrally charged, meaning that they have the same number of protons and electrons. sometimes, though, atoms lose or gain one or more electrons, and become positively or negatively charged. a positively or negatively charged atom is called an ion. an ion with more protons than electrons is positively charged. an ion with more electrons than protons is negatively charged. one common ion is a sodium ion, which has a charge of +1.

which of the following statements is true?

the ion has more protons than electrons.

the ion has the same number of protons and electrons.

the ion has more electrons than protons.

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!
