What are the properties based on modern periodic table?
Properties of elements are periodic function of atomic number. Elements with same chemical properties are grouped together.
Why there is a group of elements in periodic table?
There is a group of elements in the periodic table as the elements with same properties are clubbed together.
What are elements on the periodic table are grouped based on?
Group are based on similar properties. The elements having same chemical properties are grouped together.
What causes the propertiesof elements in a group to be simalar?
Same number of valence electrons cause same properties. The elements with same properties are grouped together. For example- the alkali metals are placed in group-1
What method did Dmitri used organize the elements?
According to Dmitri, properties of elements are periodic function of their atomic masses. He placed elements possessing same chemical properties together.
Are elements molecules?
No!!! Elements are a group of atoms of all the same type. e.g. Carbon is an element because all the atoms in carbon are carbon atoms. They all contain 6 protons, 6 neutrons and 6 electrons. Whilst one cannot pick up and hold an atom, too small, one can hold an element because it is a much larger group of atoms. e.g. one can hold the element carbon ; it is a black dust ( soot) or its allotrope a diamond. A molecule is a group of atoms chemically combined together e.g. water (H2O) , carbon dioxide (CO2). There are millions more different molecules.
Are the properties of a compound the same of the properties of its elements?
the properties of a compound are not the same as the elements that form them.
How can the periodic table identify the properties of chemical families?
Periodic table group elements with same properties together. Hence their properties can be identified.
Why it was needed to develop the periodic table?
The elements with same properties need to be grouped together. So that it is easier to study the elements
What two properties are the modern periodic table based on?
Properties of elements are periodic function of atomic number. Elements with same chemical properties are grouped together.
Do not have the same properties as the elements that formed them?
True. Compounds do not have the same properties as the elements that form them.
Do compounds not have the same properties as the elements that formed them?
True. Compounds do not have the same properties as the elements that form them.
