Elements may be classified as metals, nonmetals, or metalloids. Elements with some characteristics of metals and some of nonmetals are metalloids. Metals are on the left side of the periodic table. Nonmetals are on the right side of the table. Metalloids occur in zig-zag line on the table, separating metals and nonmetals. Here is a look at the difference between metals and nonmetals.

Properties of Acids and Bases
1. Properties of Acids
Acids are corrosive in nature.
They are good conductors of electricity.
Their pH values are always less than 7.
When reacted with metals, these substances produce hydrogen gas.
Acids are sour in taste.
Examples: Sulfuric acid [H2SO4],
2. Properties of Bases
Some properties, like a bitter taste, are owned by all bases. The bases feel slippery, too. Dream on what slippery soap looks like. And this is a foundation. Furthermore, when immersed in water, bases conduct electricity because they consist of charged particles in the solution.
They are found to have a soapy texture when touched.
These substances release hydroxide ions (OH– ions) when dissolved in water.
In their aqueous solutions, bases act as good conductors of electricity.
The pH values corresponding to bases are always greater than 7.
Bases are bitter-tasting substances which have the ability to turn red litmus paper blue.
Examples: Sodium hydroxide [NaOH],

What is a Solution in Chemistry?
A solution is much more than an answer to a complicated math problem. It is also a chemistry term! Learn what solutions are, how to identify them, and examples of common solutions!
Types of Solutions
Solutions can be classified by the states of matter of the solute and solvent. Below is a list of the possible combinations of solute in a solvent that form solutions.
Gas in gas
Gas in liquid
Liquid in liquid
Solid in liquid
Liquid in solid
Gas in solid
Solid in solid
