Given below are two statements : Statement (I) : Both metal and non-metal exist in p and d-block elements. Statement (II) : Non-metals have higher ionisation enthalpy and higher electronegativity than the metals. In the light of the above statements, choose the most appropriate answer from the option given below:
Options
- ABoth Statement I and Statement II are false
- BStatement I is false but Statement II is true
- CStatement I is true but Statement II is false
- DBoth Statement I and Statement II are true
Correct answer
B. Statement I is false but Statement II is true
Step-by-step solution
I. In p-Block both metals and non metals are present but in d-Block only metals are present p-block elements: The elements which are present in group 13 - 18 . The elements in p-blocks are of all kind metals and non-metals. Transition elements: Those elements which are in groups from three to twelve. They are called a transition because they are in between the s- block elements and p-block elements. For example, scandium, iron, zinc, etc. Transition elements are also known as d-block elements. II. EN and IE of non-
