A compound is a substance consisting of atoms or ions of two or more different elements in definite proportions joined by chemical bonds into a molecule. The elements can not be separated by physical means. Water, for example, is a compound having two hydrogen atoms and one oxygen atom per molecule. An element is a substance consisting of atoms which all have the same number of protons - i.e the same atomic number. Elements can not be broken down using chemical methods.

Elements:
1. Magnesium (Mg)
2. Calcium (Ca)

Compounds:
1. Sodium chloride (NaCl)
2. Hydrogen chloride (HCl)

Andrej [43]

<em>If a drop of dishwashing detergent is added near it, the paperclip most likely will;</em>

Soap is a surfactant that disrupts the intermolecular forces of water making the paperclip sink.

<u>The paperclip is able to float on the surface of water due to its surface tension.  </u>

<u>When soap is added to water, it reduces the surface tension. Soap disrupts the intermolecular forces that hold the molecules on the surface tightly like a film. </u>

<u>Thus, the paperclip sinks into the water.</u>

The sum of all percent abundances for magnesium is equal to 100. explain why this is reasonable.
kow [346]
Elements occur naturally in different forms called isotopes. These are the same atoms with the same number of protons but has different number of neutrons. Almost all elements exist in nature as such. The amounts of these isotopes are expressed in terms of percent abundances and since it is in a percentage units, the sum of all the abundances should equate to 100 percent or else the calculation is wrong. This is not true onlt for magnesiun but with all of the elements. The atomic mass of these elements also depends on the percent abundances of the isotopes since it is a weighted average value of the individual masses of the isotopes.
