When sodium chloride is formed from a positively charged sodium atom and a negatively charged chlorine atom, the charge on the salt becomes neutral is true
Explanation
Sodium ion ( positively charged) combine with chloride ion ( negatively charged) to sodium chloride which is neural according to equation below.
Na⁺ + Cl⁻ → NaCl (<em>neutral</em>)
Equal number of positive and negative charges add up to make neutral Nacl therefore the statement above is true.

<u>the Paleozoic Era </u>
The Precambrian era describes a period of time that pre-dates Cambrian. This time typically references the entire period of the history of earth before the formation of rocks containing identifiable fossils occurred. It covers the majority of Earth’s history and is divided into the Hadean, Archean and the Proterozoic era.
Just before the Cambrian eruption, in the Paleozoic Era the environment was oxygenated, culminating in an explosion of new life in the Proteozoic Eon (2500-541 million years ago) in the form of primitive blue-green algae named cyanobacteria and oxygen based species. Multicellular species followed later, along with structure at higher levels, and complex life. Oxygen levels grew gradually over this period of time, from low levels.
