Answer:
Noble gases
Explanation:
The noble gases are non-metals that requires the highest amount of energy to remove an electron from their shells.
The reason for this difficult is that their electronic configuration confers a stable configuration them.
- The ionization energy is the energy required to remove the most loosely held electrons in an atom.
- Due to the special stability of noble gases, it is very difficult to remove electrons from an atom of noble gases.
Answer:
Explanation:
Volume is defined as the space occupied by an object or substance irrespective of its state of matter.The conversion used from millimeter to liter is:
1 milliiliter = 0.001 L
Therefore, we can convert the volume of sample from 2.5 ml in liters as follows.
2.5 ml in liters = 2.5ml x 0.001 L/1ml
= 0.0025 L
Thus, we can conclude that the volume of given sample in liter is 0.0025 L
Hope this helps! :)
Answer:
Among Na ,K , Pb , Li , The atom which does not react with water is :
<u>Pb</u>
Explanation:
Li : Reacts slowly with water
Na ,K : Reacts vigorously with water
Pb : It does not reacts with water because :- Pb oxidize in presence of atmospheric oxygen to form lead oxide (PbO) . this PbO form a layer over the surface of Pb and make it inert to water.
I would say the answer is liquids
The rows are called Periods.
