Describe how boiling point and melting point vary with respect to atomic number.

As atomic number increases, boiling point/K increases due to there being more electrons, which create a larger strength of negative charge around the nucleus of the atom.

120,630,890

step-by-step explanation:

110+10=120,620+10=630,880+10=890

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
