Chlorine has seven valence electrons. It can form a bond with two atoms of Magnesium (two valence electrons). Is this an example
Schach [20]

Answer:

The answer to your question is Ionic bonding. Magnesium loses 2 electrons and Chlorine gains 1 electron

Explanation:

An Ionic bond is formed between a metal and a nonmetal and the difference of electronegativity is higher than 1.7. In this type of bond, metals lose electrons and nonmetals gain them.

Covalent bonding is formed between two nonmetals and the difference of electronegativity is between 0 and 1.7. Elements share electrons.

Process

Electronegativity of Mg = 1.31

Electronegativity of Cl = 3.16

Difference = 3.16 - 1.31

                  = 1.85

          1.85 > 1.7 then the bond formed is Ionic

Magnesium loses 2 electrons and Chlorine gains 1 electron

A piece of aluminum has a volume of 12 cm3and a mass of 32 g. What is its density? Do not forget the units.
Contact [7]

Answer:

<h3>The answer is 2.67 g/cm³</h3>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume} \\

From the question

mass of metal = 32 g

volume = 12 cm³

The density is

density =  \frac{32}{12}  =  \frac{8}{3}  \\  = 2.6666666...

We have the final answer as

<h3>2.67 g/cm³</h3>

Hope this helps you
