Question
This group of elements sit along a stair step line on the periodic table and have properties of both metals and non-metals:
- Radioactive elements
- Halogens
- Transition metals
- Metalloids
Hint:
Metalloids have properties of both metals and non metals.
The correct answer is: Metalloids
- A radioactive element is one with an unstable nucleus, which radiates alpha, beta or gamma radiation and gets converted to a stable element.
- Halogens are in the 17th group of periodic table chemically related elements.
- Transition metals are mainly d block elements with multiple oxidation states.
- Metalloids are a group of elements sit along a stair step line on the periodic table and have properties of both metals and non-metals.
