Reaction Rate is the rate at which a substance undergoes a chemical change.
Answer:
True
Explanation:
Atomic radius can be defined as a measure of the size (distance) of the atom of a chemical element such as hydrogen, oxygen, carbon, nitrogen etc, typically from the nucleus to the valence electrons. The atomic radius of a chemical element decreases across the periodic table, typically from alkali metals (group one elements such as hydrogen, lithium and sodium) to noble gases (group eight elements such as argon, helium and neon). Also, the atomic radius of a chemical element increases down each group of the periodic table, typically from top to bottom (column).
<em>Hence, the atomic radius of phosphorus is smaller than the atomic radius of magnesium. Basically, the atomic radius of phosphorus is 98 pm while the atomic radius of magnesium is 145 pm.</em>

A shows the physical features of the land
Explanation:
A topographic map is a map that shows the physical features of the land area. Rivers, streams, mountains, valleys, hills and other physical features.
- A topographic map is made up of series of contour lines.
- The contour lines are lines that joins places of equal elevation.
- All places on the contour lines have the same elevation.
- Using the contour lines, we can understand the landforms in an area.
- Other map keys are used to delineate settlement patterns, streams, churches, dams and the like.
- Most topographic maps are used as base maps for making other maps.
