An atom that has fewer neutrons than protons and more electrons than protons is a(n) ion.

A negative ion... electrons have a negative charge, and protons have a positive charge. As can be seen, if there is more negative electrons, there is a negative ion!

There is no graph to look at on here, but i shall explain them to you. a line graph is just in its title it’s a graph with a line running through the dots to show an increase or decrease. a bar graph is used to show how much or how little something is so a comparison. a scatter plot is used to graph points to tell the data. and i don’t know what a histogram is.
