प्रश्न
What are transition metals? Give four examples.
उत्तर
- Transition metal is an element whose atom has an incomplete d sub shell or which can give rise to cations with an incomplete d sub shell.
- They occupy the central position of the periodic table, between s-block and p-block elements.
- Their properties are transitional between highly reactive metals of s-block and elements of p-block which are mostly non-metals.
- Example: Iron, Copper, Tungsten, Titanium.
