A period on the periodic table is a horizontal row. The atoms in this row show a trend in their width, and in the amount of work needed to make them an ion, among the fe â¦ w other similarities.
A coordinate grid has two perpendicular lines, or axes, labeled like number lines. The horizontal axis is called the x-axis. The vertical axis is called the y-axis. The point where the x-axis and y-axis intersect is called the origin. The numbers on a coordinate grid are used to locate points. Each point can be identified by an ordered pair of numbers; that is, a number on the x-axis called an x-coordinate, and a number on the y-axis called a y-coordinate. Ordered pairs are written in parentheses (x-coordinate, y-coordinate).
Axis limits, specified as a vector of four, six, or eight elements. For Cartesian axes, specify the limits in one of these forms: [xmin xmax ymin ymax] â Set the x-axis limits to range from xmin to xmax. Set the y-axis limits to range from ymin to ymax.
