What two properties are the modern periodic table based upon?
Mendeleev created the first periodic table based on atomic weight. He observed that many elements had similar properties, and that they occur periodically, hence the name, periodictable. From this, he made the periodic law.
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.
What are the genernal properties of the elements in the first two groups on the left side of the modern periodic table?
they are gasses
How many examples of the Periodic table can you find?
I can find only two types The Mendeleves Periodic table based on Atomic weight of elements and The Modern Periodic table based on Atomic number of elements.
How does the periodic table allow us to predict the properties of a bond between two atoms?
Periodic table determine chemical properties. It later helps in predicting the bonds formed by elements.
How could modern periodic law remove various anomalies of mendeleevs periodic table?
1.) The atomic mass in Mendeleev's periodic table does not increase regularly. therefore, it was impossible to predict the number of elements between two elements.The Modern periodic table has been made according to the increasing atomic number (Modern Periodic Law states that 'The properties of an element are the periodic function of its atomic number). The atomic number gives us the number of protons in the nucleus of an atom. the atomic number increases by one as we go from one element to the next. thus, this makes it easy to ascertain how many undiscovered elements may be there between two known elements.2.) Mendeleev's periodic table was made according to increasing atomic masses. we know that of an element have same chemical properties and atomic number, but different atomic masses. So, the concept of isotopes can not be satisfied.The Modern periodic table is according to increasing atomic numbers. Therefore, the problem of isotopes is easily dealt with.
What are the general properties of the first two groups of the modern periodic table?
they're metals, to be precise gr1 alkaline gr2 alkaline earth. Both have metallic properties: conduct heat and electricity; malleable/ductile etc. Gr1 metals are soft and very reactive.
What periodic table group has similar chemical properties but different physical properties?
Group 17, the halogens have similar chemical properties. However, at standart temperature and pressure, two are gases, one is a liquid and two are solids.
What are the two uses of alkali metals?
all family of periodic table thier properties and uses
Where does the periodic table become wider?
In the modern day periodic table, the periodic table gets wider in periods two, four, and six.
In the periodic table which two properties of an element are usually given as numbers?
proton number and atomic mass
What are two properties the metal family share in the periodic table?
they produce extreme heat when mixed with water
