The Modern Periodic Table
The Modern Periodic Table: Overview
In this topic, we shall study the modern periodic table in detail along with the position of elements in modern periodic table. We will also study about valencies and atomic size in detail.
Important Questions on The Modern Periodic Table
If valence electrons in iron are why is it not in zero group element?
What are the salient featured of modern periodic table.
An atomic number of an element Z is 16. State the formula of the compound between Z and hydrogen.
There are three elements E, F, G with atomic numbers respectively. Classify the elements as metals and non-metals.
Select whether the following statement is true or false:
The elements in the Modern Periodic Table can be classified into four parts- s-block, p-block, d-block and f-block elements.
Select whether the following statement is true or false:
The modern periodic table is used to quickly refer to information about an element, like the atomic number and chemical symbol. The modern periodic table’s arrangement also helps in discerning the trends in the properties of elements, including electronegativity, ionization energy, and atomic radius.
