Sunakshi is completed her science chapter where she wrote some statements on “Periodic Table”. She wants to know whether the statements are correct or not? Sunakshi wants to take help from you:
In Mendeleev’s Periodic Table, gaps were left for the elements to be discovered later. Which of the following elements found a place in the periodic table later?
Consider the following statements and choose the incorrect one:
According to Mendeleev’s Periodic Law, the elements were arranged in the periodic table in the order of
Rahul is writing some statements about “Periodic Table”. Choose the correct one(s):
why did Mendeléev select Oxygen and Hydrogen to test in 10th Science Chapter 5?
Mendeléev selected hydrogen and oxygen to test the chemical properties of elements as they are very reactive and formed compounds with most elements.
What were the limitations of Mendeleev’s Periodic Law as in 10th Science ch. 5?
1. Isotopes of all elements posed a challenge to Mendeleev’s Periodic Law.
2. The atomic masses do not increase in a regular manner in going from one element to the next. So it was not possible to predict how many elements could be discovered between two elements — especially when we consider the heavier elements.
3. No proper place assigned to Hydrogen.
What is modern periodic law according to Class 10 Science Chapter 5?
The modern periodic law states that Properties of elements are a periodic function of their atomic number.
What happen to atomic radius of atoms when we move from left to right in a period in 10th Science?
The atomic radius decreases in moving from left to right along a period. This is due to an increase in nuclear charge which tends to pull the electrons closer to the nucleus and reduces the size of the atom.
