Answer:
Cl
Explanation:
Electronegativity increases as you move up and to the right of the periodic table. For example, Florine is the most electronegative element.
The answer would be a mixture. A mixture is when two or more substances are combined to create heterogeneous mix, where the substances do not combine with each other in an equal or even state, but just sit together.
Physical change is a change that occurs in a substance that does not change the identity of the substance. It does not alter the chemical structure of the molecules ehile chemical change involves the breaking of the bonds in the substance forming new substance. To identify a metal physically, we can use properties like their boiling and melting points. We can determine at what temperatures these metals melt or boil then from literature we compare the values. Another properties that can be looked upon to are hardness, color and density. For chemical methods, we can allow it to react with substances, that will produce precipitates containing the metal in question. Also, we can use other methods like titration method. All chemical methods involves the use of chemical reactions.
