Arrange the following elements in order of increasing first ionization energy.

Mg, Al, Si, P, S

The answer to your question is  Al, Mg, Si, S, P

Explanation:

First ionization energy is the energy necessary to remove an electron from an atom in a gaseous form.

Element           First ionization energy (kJ/mol)

Magnesium              737.7  

Aluminum                 577.5

Silicium                    786.5

Phosphorus              1011.8

Sulfur                        999.6

Order:   Al, Mg, Si, S, P

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates

b.

the accuracy of the data.
