What do you notice with the number of valence electrons?
The number of valence electrons determine the chemical properties of a particular element. For example, elements in group 1 tend to donate its valence electron away to produce its stable +1 ion. It also explains the formation of -1 ions from group 17 elements (halogens).
What explains their solutions properties?
This depends on the nature of solvent and solute, concentration of solute, temperature, etc.
What best explains the role of a catalyst in a chemical reaction?
The phenomenon which best explains the role of catalyst in a reaction is that the catalyst lowers the Energy of Activation :)
What is the chemical property that explains how readily one form of matter turns into another form of matter?
You think probable to chemical reactivity.
What are the advantages of modern periodic law?
1. The classification of elements is based on the atomic number, which is a more fundamental property. 2. The reason for placing isotopes at one place is justified as the classification is on the basis of atomic number. 3. It explains the periodicity of the properties of the elements and relates them to their electronic configurations. 5. The position of the elements that were misfits on the basis of mass number (anomalous pairs like argon and potassium) could be justified on the basis of atomic number. 6. The lanthanides and actinides are placed separately at the bottom of the periodic table. 7. The table is simple, systematic and easy way for remembering the properties of various elements as it is based on the electronic configuration.
What was the problem with Dobereiner's periodic table?
Dobereiner is remembered for what were called "Dobereiner's Triads" which are groups of three elements having similar chemical properties. This is a forerunner of the periodic table, but it is not actually a table, and it does not offer any explanation for the chemical similarities observed within the triads. Mendeleev's Periodic Table of the Elements shows the relationship of every element to every other element, and explains why they all have the chemical properties that they have.
What unites and explains a range of observation?
A theory unites and explains a range of observations.

Why is the periodical table used?
So you can classify the elements into groups.
What law explains relationships between different chemical compounds that contain only the elements carbon and oxygen?
This is the law of definite proportions.
Why did Mendeleev set up the periodic table the way he did?
Because he was creating a book called the Principle of Chemistry and he noticed the pattern in every elment. So he made a table or (chart) called Periodic Table of Elements.
Why would something be a law and not an observation?
A law explains what is observed.
What is a testable statement that explains a series of observation called?
hypothesis
What explains the properties explains metals?
The electrons they contain, which have the ability to move freely
The big bang hypothesis explains?
Hubble's red shift observation.
Which best explains the term observation?
Information gathered through the five senses
Is it true that a scientific hypothesis best explains certain observation facts?
no its theory
