Question
There is no p - block elements in the first period of the periodic table.Question 19Answera.Trueb.False
Solution
The statement "There is no p-block elements in the first period of the periodic table" is true.
Here's why:
The first period of the periodic table only contains two elements: hydrogen and helium. Hydrogen is in the s-block of the periodic table, and helium, although it is in the s-block in some versions of the periodic table, is often placed in the p-block due to its similar properties to the noble gases (which are p-block elements). However, helium itself does not have any p electrons; its electron configuration is 1s².
The p-block starts from the second period with the elements boron (B) and carbon (C).
So, the correct answer is a. True.
