Atomic Mass.
Probable you think to the periodic table of Mendeleev.
You think probable to Dimitri Mendeleev.
A reacted element is called Reactant. It is present on left side of chemical equation.
The periodic table organizes all of the elements by their physical and chemical properties, so elements with similar properties go in the same vertical column, or group or family, i.e. the Alkali earth metals are the first column of the periodic table, all of the elements in that group are highly reactive with water, and will either fizzle or explode when dropped in water. Therefore, scientists can use the other elements in a group to predict the properties of another element in the group that they do not know about. Also, there are periodic trends in the horizontal rows of the table, called periods. For instance, the atomic radius of the elements is the biggest on the left, and gradually gets smaller as you move to the right. Hope this helps! :)
Atomic Mass.
Atomic mass in a 'periodic' way Hope this helps :p
i think it is a earth have spoilt.
A substance that has properties different from the chemical elements in it is a chemical compound. A chemical compound is built from chemical elements that are chemically bonded together. And the "finished product" will have chemical properties that are unique to that compound, and different from the properties of the substances that make it up.
Groups 3-12 have elements with the most diverse set of properties in the periodic table. They are transition elements.
I suppose that you think to chemical elements, not to compounds. Dimitri Mendeleev is credited for the creation of the periodic table of elements.
Probable you think to the periodic table of Mendeleev.
At that time, scientists knew some of the properties of more than 60 elements. However, no one had organized the elements according to these properties; making it harder for scientists to understand how elements interact with each other.
You think probable to a chemical compound.
I think you just have to learn them, although elements in the same group or period could share properties.
turtles i think
