Why is the mendeleevs table called the periodic table?
Because the properties of the elements change in a periodic fashion. In the early versions, when fewer elements were known, the chemically similar elements were thought to occur every eight positions.
What is the name of the table of elements?
A Periodic table The Periodic Table of the Elements.
How many elements are you periodic table?
118 elements are in the periodic table of elements; some of them are still unnamed (January 2013).
What is the name of the 50 elements?
There are 118 elements. They are on the Periodic Table.
What are the pure elements on the periodic table?
All the elements from the periodic table can be obtained as pure elements.
Do the relative positions of sucrose in the periodic table agree with the theoretical prediction about the kind of compound these elements should form?
Sucrose is an ionic compound!!
What is the greatest triumph about mendeleev's periodic table?
The greatest triumph of Mendeleev's periodic table was his predictions of the existence of the undiscovered elements.
How do you predict if a covalent compound will be polar or nonpolar based on the elements' positions on the periodic table?
Yes
When was the periodic table created and who by?
The periodic table was created by Dmitri Mendeleev in 1869. He organized the elements based on their chemical properties and their atomic weights, creating a system that arranged the elements into groups and periods. This arrangement allowed for the prediction of missing elements and became the basis for the modern periodic table.
What is medeleev's prediction?
It's probably Mendeleev you're after. He came up with the first version of a Periodic Table of the elements, and used this to predict the properties of elements that hadn't been discovered at that time.
What properties of these elements are indicated by their positions in the periodic table?
For example metal or nonmetal character, radioactivty, atomic weight, reactivity.
How are the elements arranged?
atomic number

How do chemists organize information about elements?
By grouping the elements on the Periodic Table.
Multiple choice questions on periodic table of element?
- the rational arrangement of chemical elements - elements in groups - elements in periods - atomic number - prediction of chemical and physical properties of elements
What is a chart that lists all the known elements?
It is called the Periodic Table of Elements.
